After reading this post, you should feel confident enough to create a fantastic resin casting using one of these amazing silicone molds.
What is Resin Casting?
Resin casting is a method of making models out of a thermosetting polymer. A thermosetting polymer called epoxy resin is one of the most common liquids used to cast these models. Other resins, such as fiberglass or polyester resin are also used in resin casting, but we recommend epoxy resin if you are a beginner!) A mold is used, usually made of silicone or plastic, and epoxy resin is poured into the mold. The defining quality of a good casting resin is its low viscosity. Low viscosity liquids are thin. The thin liquid is best suited to fill all voids in a mold easily, and then harden to form your casting. Another quality of a low viscosity epoxy resin is its long working time and cure time. As a result, bubbles that have been introduced into the epoxy resin while mixing, have more time to rise to the surface and pop while the casting is curing in the mold. For more detailed information on epoxy resins and what products work best for resin casting, check out Best Epoxy Resin for Art Projects.
One of the best epoxy resins for casting is Incredible Solutions Epoxy Resin.
This is one of our go-to epoxy resins for castings because it releases air bubbles well, self-levels, and consistently cures hard.

3. Oil Burner Silicone Mold with Tea Light Holder
We are in love with this awesome aroma diffuser silicone mold for resin! This mold allows you to cast an oil fragrance burner using epoxy resin. Oil burners, also known as aroma diffusers, keep rooms smelling beautiful year-round. The neat part about making your own oil burner is you can make one that matches your décor perfectly!
The silicone mold comes with a little glass dish that sits inside the casting. You can place your favorite wax scent cubes in the tray, place a tea light underneath the structure, and melt your way to smelly goodness! Since the day we cast our first aroma diffuser, our house has been smellin’ BOMB AF. True story, bro!
Not only is this mold great for making your own personalized diffusers, but how cool would it be to create your holiday gifts this year? I know what you are thinking. Handmade gifts are tacky, even annoying, at times. I mean, who actually appreciates receiving 45 different handmade bath bombs each Christmas? Certainly not I.
Seriously guys, enough with the bath bombs… I don’t even have a bathtub!!
A handmade aroma diffuser though? Yeah, I would be happy with a few of those!
Especially because the resin castings we were able to create using this silicone mold truly look like they were taken straight off the shelves of Pier One.
4. 3-Tier Cupcake Stand Silicone Mold for Resin
This three-tier cupcake display silicone mold has been around for a while and you may have seen it already. However, the different resin castings that I’ve seen artists come up with using this mold are astounding.
In fact, I am planning to use this resin mold set to create cupcake displays for my sister’s upcoming wedding. I plan on using resin that matches the theme of her wedding, which would be impossible to find if she tried to buy these at the store. It is simple to match her theme colors with epoxy resin pigments. Plus, I can add bling, which is a must at a wedding (Obviously not in a tacky way, but more of a classy glamorous way.) They will be the hit of the party! Aside from the bride, I mean….obviously 🙂
Watch our blog for an upcoming post showing the process used to make a 3-tiered cupcake stand out of resin for my sister’s wedding. I may also film a reaction video if anybody is interested.

5. Resin Agate Coasters Silicone Mold Set

If you follow my blog you know that one of my top recommendations for silicone coaster molds is diamond-edged molds. In fact, one of the highest-ranked coaster molds I recommend in 16 Best Silicone Coaster Molds for Resin has diamond edges like the ones in this mold set. However, while browsing Amazon for hours the other day, (Don’t judge me, I got stuck because I found so many cool molds and I’m sharing them with you, so shush!) I found this set of ten diamond-edged agate-shaped silicone coaster molds and I had to buy them. I thought things couldn’t get any better, but they did with this mold. Love love love.
6. Decorative Flower Silicone Molds
Check Amazon Price
Okay, okay so I’m honestly not quite sure what these molds make. The title is not exactly straightforward. However, I thought these would be really cool as a centerpiece for your coffee table or even hung up as an ornament. Since they are druzy molds they the resin casting will shine beautifully when the sun or artificial light hits the casting. I have not seen many resin artists try these molds yet, so you should definitely be one of the first! They are so cute and I have so many ideas for them and so little time to cast all of them! The set comes with 5 different flower molds:
One piece is a 7.8” flower mold with an irregular center cutout that can be used to make a bonus casting, and the other 4 molds are 4.1”x3.8” and shaped like flowers with five sides. (See image)
7. Coffee Pod Holder Resin Molds Kit
Check Amazon Price
This silicone mold is for all the coffee lovers out there, and by ‘coffee lovers’ I mean those of you who like to pull a little pod out, stick it in your Keurig and press the button. Ahem, it may be a shortcut, but it sure tastes good! My sister uses a French press, and I just don’t understand why she goes through so much work for a cup of coffee when Keurig pods are so delicious. Anyway, if you or someone in your life is a Keurig addict, like me, this is the resin mold for you. This amazing silicone resin mold makes castings that hold your coffee pods for your Keurig machine. (or copycat brand machine :)). I recently purchased this mold and made one for myself right away. Now that my family has come over and seen my bright red resin coffee pod towers sitting next to my Keurig filled with delicious options of flavored coffee pods, everybody wants me to make them one! (Aside from my sister obviously.) Plus, the coffee pod tower holds 16 capsules, which is actually more than the pod holder I bought at HomeGoods last year. Winning!
8. Straw Topper Silicone Molds
Check Amazon Price
Okay, so not only is this silicone mold plain awesome, but it’s beginning to become a necessity for some states. California, and many other states, have outlawed the use of plastic straws to protect our environment and clean up our landfills. I’m not sure if it’s working, but if you would like to be a crusader for the environment you need to purchase this silicone resin mold. It includes three different styles of molds to make adorable straw toppers so you can always identify whose drink is whose.
This mold would have been very handy when I visited California last! I had to purchase my own straw to drink my margaritas. I had to purchase a metal straw and switch it to each new glass I ordered. If you lose your straw, you have to pay another five bucks to buy another one.
So, the more Margaritas I had, the harder it became to keep track of my metal straw, considering everybody else had the same exact one. Had I had this silicone mold at the time, I could have plopped on a nice little straw topper that would make my straw completely unique and never lost my straw again.
These little straw topper silicone molds are so cute and come in a variety of different shapes. Check them out, you won’t be disappointed with your resin casting
9. Hand/Construction Tools Silicone Molds
Check Amazon Price
These hand construction tool silicone molds are way cool. I mean, who thought of that? Who was sitting in their house one day and was like, “I need to use my epoxy resin to cast some more construction tools?”
Whatever Carpenter that was, I’d like to meet him.
Anyway, you can check out Instagram for some amazing renditions of this resin casting, including glittery pink rainbow construction toolsets. They can be used as decoration, or, if you have hard-type resin, you could potentially use them as construction tools as well.
The thing I like most about these molds is that they aren’t really gender-specific. A lot of molds tend to the categorized in the ‘girly’ category, but these could turn out pretty masculine looking if the right colors or embedded objects are used. (P.S. This is not a statement to offend any sort of gender fluidity activists out there, I just made an observation.) You do you boo.
10. Dishwasher Clean/Dirty Sign Silicone Molds
Check Amazon Price
I totally don’t blame you if you choose not to believe the story I’m about to tell you, but I swear it’s true…
When I was about 12 years old, I used to think of things that would change the world if I invented them. I totally came up with this idea.
However, I thought that a dishwasher should tell you when it’s clean or dirty automatically.
The dishwasher signs that you can make using these silicone resin molds are neat, but you do have to flip the sign yourself from clean to dirty.
My invention somehow involved the dishwasher being able to tell if the dishes were clean or dirty by itself, without being thrown off if the door of the dishwasher is opened and shut a few times before it gets unloaded. I know you know what I’m talking about.
There have been some inventions like this on the dishwasher face itself, but none have been able to read whether you actually unloaded the dishwasher the last time you opened the door to grab a single clean spoon because you were too lazy to unload the entire thing!
Anyway, this mold is amazing. I mean what will they think of next,? Well, I guess we’re about to find out!
11. Guitar Pick Resin Silicone Molds
Check Amazon Price
Yes, you can cast guitar picks out of epoxy resin using this silicone mold. The first time I saw these and purchased them, (because once you see these how can you not purchase them immediately?) I wanted to start offering them in my shop.
However, I don’t know how to play the guitar and I’m not current on the music community trends regarding what makes a ‘cool’ guitar pick. If you have any ideas, please leave them in the comments below. I would love to start offering some of my own guitar pick creations, but I must not be embarrassed by all those talented musicians looking for guitar picks… on a resin art site… yeah…
These molds are great, and if you are a musician yourself, well I don’t know how you haven’t already clicked the button to buy them…
Or maybe you have, and I’m just speaking to myself now.
Okay, I’m going to shut up.
Oh, one more thing. The set also includes a mold to make an adorable carrying case for your guitar pick resin castings.
12. Large Serving/Vanity Tray Silicone Molds
Check Amazon Price
Having a serving tray mold is always handy for those of us who like to plan gatherings or have friends over. The fact that you can cast a serving tray to match the theme of your gathering should really be exciting to you.
I last used my mold to cast a movie-themed tray. I put popcorn kernels, ticket stubs, red hot candies, and old film rolls (from the days before digital) into my tray and served snacks with it for my horror movie marathon. it was a hit.
I served drinks and popcorn and got a ton of compliments.
These molds can also be used to cast vanity trays, if you have the urge to glam it up, you could use the tray to display your Eau de Perfumes
13. Spoon Holder Silicone Mold
Check Amazon Price
These spoon holder silicone molds are pretty handy to have around. I actually use this mold to hold some of my silicone utensils while I am doing resin projects. However, this is a really nifty mold to have if you don’t have somewhere to rest your spoons or spatulas while you are cooking.
This resin casting can be made to match the colors of your kitchen and will look really cute sitting in the middle of your stove even when you’re not using it.
A spoon rest is one of those kitchen items that many people forget to purchase when stocking their kitchen. If you can whip one up real quick overnight using this mold, you won’t have to remember to put it on the grocery list for the next time you go to Walmart!
You’re welcome. I do particularly enjoy a silicone mold that makes items that are useful for everyday life like this one does.
14. Flower Vase Silicone Mold
Check Amazon Price
This silicone mold makes the cutest little flower vase I’ve seen in a long while. The mold is square and forms a circle in the center where you can place a little glass tube to display a few flowers. The little glass tube is also included with the molds when you purchase them.
I had never even seen this type of vase anywhere else before I found this mold. However, I think they are too adorable to pass up.
15. Pointed Crystal Tower Silicone Molds
Check Amazon Price
This silicone resin mold is for all you spiritualists out there! Those of you who take your herbal tea hanging upside down in a yoga trapeze every morning! Don’t worry, I’m not judging.
I actually bought a yoga trapeze a few months back and hung it up on my ceiling. Putting it up was probably the most intensive exercise I’ve had using the trapeze so far unless you include the extracurriculars my boyfriend and I have used it for. Wink wink!
Ok, let us keep this G-rated! Sheesh.
Anyway, these silicone molds are used to make crystal towers out of resin. You could cast stones, flowers, or crystals in them to use for meditation or just make some pretty crystal towers to display around your home.
I have chosen to display my crystal resin tower next to my incense burner! (And yes, my incense burner was made using another silicone mold for resin!!! Check it out below)
16. Ouija Board and Planchette Silicone Molds
Check Amazon Price
Spooky! I bought this Ouija board silicone mold a while back but have not had the nerve to cast anything with it yet. It is a neat idea and, by all means, if you know how to use these responsibly, this is a great mold for you. Whenever I pull mine out I get weird flashbacks to the movie Jumanji, which scared the crap out of me as a kid, and I chicken out. I know, the kids in Jumanji were not using an ouija board, but for some reason I envision myself waking up a stampede of spirits. I always feared that the spirits I could awaken with an Ouija board would come at me like the stampede scene in Jumanji…freaky. Seriously though, total props to you if you know how to use an Ouija board safely.
17. Incense Burner Silicone Molds
Check Amazon Price
Here is the other awesome silicone mold that belongs in the spiritual category! This mold is pretty neat. The casting has a perfect-sized hole in one end to stick your incense into and the rest of the casting collects the ashes while the incense stick burns. What a great way to keep the counters clear of ash while completing your yoga sess. I mean who wants to clean up a mess after meditating?? Not this hippie 🙂
Bonus, this kit includes mica powders to color your resin with!
18. Bluetooth Earbuds Case Silicone Mold
Check Amazon Price
This Bluetooth (wireless) earbuds case silicone mold is one that had my jaw hanging lower than usual when I first came across it! What a great little gift for kids going back to school. I made one with dried flowers and silver leaf cast into the resin for my niece going back to school. For my nephew, I cast stickers from his favorite sports team into the mold.
They were a hit! Both kids said their friends thought they were so awesome and wished they had an aunt that was cool. 🙂 Damn straight!
19. Night Light/ Tap Light Silicone Molds
Check Amazon Price
Another really creative silicone mold, this night light mold allows you to display in resin, a gorgeous little scene that comes to life when you tap the top of the light.
You could cast flowers or sparkly glitters in the mold. Another neat way to use this mold is to place a black silhouette Into the resin. When turned on the silhouette is backlit by the light and will cast a shadow onto an adjacent wall or ceiling. If you want, it could be a never-ending hand puppet! Joking, kind of.
Anyway, the mold includes a backplate with a bulb and circuit system that allows you to turn the light on and off. When switched on you can still tap the light on and off.
20. Ballpoint Pen Silicone Molds
Another handy mold to have around, this mold ensures you will never have to scour the house for a pen again! Instead, use some UV resin, plop it in the pen mold with one of the included ink cartridges, add some bling if you can’t resist, pop-under a UV light and you will have a working pen in less than ten minutes! Worth it! Especially because this silicone mold set comes with plenty of ink inserts, in red blue, and green! You could make enough pens to last you a while. Or, if you work at one of those businesses where pen thievery is abundant, you could teach your customers a lesson by casting some razorblades or thumbtacks into a few of your resin pens. It may sound sinister, but I promise, your pens will stop disappearing.
Also, this kit comes with three different shaped pen molds, as well as 75 ink cartridge refills in your choice of red, black, or blue. You will have pens for days!
21. Shot Glass Silicone Mold
Check Amazon Price
Size: 4 Nice 2” x 1.3” round Ice Cups – The Ice Glass will hold 1oz
Okay, so needless to say this is of my favorite silicone molds for resin casting. I use leftover resin from my wall art and pour it into these molds to make awesome shot glasses. In fact, check them out at my store. These are probably some of my most popular items.
These are another really handy silicone mold to have laying around. Let’s say you don’t have enough shot glasses for your evening soiree. If you have some quick cure, non-toxic resin lying around, you could whip up four extra shot glasses with this mold and be ready for your evening drinking debauchery!.
Or, if you had more time on your hands, you could cast different objects into these shot glasses like bottle caps, bullets, or jelly beans! The options are literally endless and some people have come up with some really interesting designs.
I believe these silicone molds were originally intended for making ice cube shot glasses. You fill them with water and place them in the freezer and voila you have your shot glasses made of ice. You can skip chilling your liquor in the Shaker before taking your shots!
So, when you buy these silicone molds you’re really getting a two-for-one.
Another great way to use these is to fill them with your favorite juice or cocktail mix and freeze them. Then you won’t need a chaser for the next shots you take at your next party. I used limeade in these molds recently and froze them. These were some of the best tequila shots I’ve ever taken.
If your guests don’t gobble up the frozen shot glasses right away, have them throw them into the blender, add some more tequila, a can of beer, and you have a batch of slushy frozen margaritas!
Don’t forget to use the resin straw toppers you cast using your silicone straw topper molds!!!
Here is a set of handmade, one-of-a-kind, wood and resin shot glasses we have available in The Craftelot Resin Art Shop. Click on the image to view the complete selection of shot glasses available, or contact us for custom orders.

What a great way to have a kid participate in decorating and designing his or her own space!
23. Perpetual Calendar Silicone Mold
Another silicone mold for the spiritualists out there, this perpetual calendar silicone mold is way neat. Have you ever wondered how you could track the phases of the moon in relation to the days of the week or the months of the year? Well, this silicone mold lets you do just that! The resin casting fit perfectly together after demolding and the final piece is a great conversation starter. This can also be used as an educational tool for your kiddos if you are teaching them about the passage of time and the moon phases!
24. 3 Pieces Koi Fish Silicone Molds for Resin Casting
This silicone mold comes in three pieces. The mold makes koi fish and they look really neat if you cast them into an aquatic scene after demolding. For example, take a wooden bowl, and set your koi fish casting on the bottom. Mix transparent blue pigment into resin and pour on top of your koi fish in the bowl. It will look as if your koi fish is swimming around in the bowl. The 3-dimensional qualities of this type of project are really neat!
25. Tarot Card Silicone Molds
The last of the spiritualist silicone molds on our list, these molds make tarot cards. If you are into that kind of thing or want to gift a tarot set to a friend who is, this is the mold for you.

28. Calendar (Weekly and Monthly Planner) Silicone Molds
This reusable calendar is super neat. You can cast a weekly/monthly planner and design it however you want. Then using dry erase markers, get your schedule for the week down on the calendar. Using a wet rag you can erase what you wrote and reuse the calendar. I love the fact that you can cast this to match whatever décor is in your office. Also, you could add sports teams emblems or other favorite themes and hand them out to your coworkers at the office. They are perfect to keep in your cubicle or on your door to display when you are in a meeting.
29. Coasters and Coaster Holder Silicone Molds
We had to include this mold. Mostly because it also has a holder for the coasters, which you can cast to match your coasters. Initially, when I started making coasters I would think about how handy it would be to have a holder for the sets of coasters I was making. Well, this mold made my wish come true! This kit is great because it comes with a set of 5 square coaster molds with a square holder mold, as well as a set of 5 round coasters molds with a round holder mold.

Factors to Consider When Buying Silicone Molds for Resin Casting
A silicone resin mold, no matter how cool the object it casts is, must rank high in multiple ranking categories before we feel comfortable recommending it to our readers. We have tried each of these molds and provided an honest review of each. We have not included resin silicone molds that gave us issues, resulted in bad casts or molds that are just crap quality.
The factors to keep in mind when looking to buy a silicone resin mold, are as follows:
- Thickness: Flexibility Ratio
- Easy to clean
IMPORTANT: To make this particular silicone resin mold recommendation list, the silicone resin mold also had to be super cool and unique. We only included molds that would make the least crafty of readers excited to try a resin casting! We think we succeeded. You let us know in the comments below.
How These Molds Made Our ‘Best Of’ List
Our list of the most interesting silicone molds for resin casting only includes products we have used ourselves. These silicone molds for resin casting all meet our quality standards for use, so we feel comfortable recommending these products to our readers. We also just thought these molds were really unique. I mean who doesn’t want to make custom keycaps out of resin or new dog tags for their pet out of resin? They were just too neat to not share with you!
Good Quality and Durable
One of the main reasons why silicone molds for resin casting are worth investing in is their reusability. Silicone resin molds are a great way to minimize waste in the environment and for this reason, it is important to get one that is quality-made and durable.
Buying durable molds is also financially beneficial to you. Constantly having to replace your silicone molds is a hassle and costly. You will save more as a result of the resin mold’s longevity instead of wasting your hard-earned money on numerous bad-quality ones. All silicone resin molds included in our list are top-quality and will last you and your family through countless art projects.
NOTE: There is no such thing as a silicone mold for resin casting that lasts forever. The more you use your molds, the faster they will need to be replaced. However, if you follow our silicone mold care tips and storage recommendations, these molds will last longer than many others on the market today. Check out Silicone Mold Care Recommendations.
Thickness: Flexibility Ratio
This category for ranking silicone molds for resin casting overlaps in many ways with the first category we mentioned. For example, a durable silicone mold is usually also a quality mold. However, thickness is taken into account with another factor in mind: flexibility.
A more flexible mold means an easier demold of your resin casting. Thickness and flexibility may seem in direct conflict. For example, it seems that the thicker a substance, the less flexible. However, many companies have been able to find the ‘sweet spot.’
The sweet spot we are referring to is the perfect ratio between thick and flexible. Obviously, the thicker the better, but if a mold is too thick, making it impossible to remove the resin casting, the mold becomes almost useless. We can not in good conscience recommend a mold that is extremely frustrating to demold.
In other cases, molds that are too thin, or flexible, rip during the demold process and sometimes during storage or cleaning!
The correct ratio for a silicone mold is one that is thick enough to be considered good quality and flexible enough to get a resin casting out of the mold with ease.
When it comes to nonstick surfaces, there is nothing that beats silicone. It is the ultimate nonstick workspace for your arts and crafts needs. Even the stickiest of resins and adhesives are not going to faze your silicone mold if it has been properly made. However, and we are not positive why some silicone molds are ruined after one casting.
We believe this could be a manufacturing default where the silicone and its catalyst were not mixed properly. However, rare, we already keep this in mind when rating.
Note: Using too much heat on your molds will cause your resin casting to stick to your mold and may completely ruin your mold so follow proper precautions for using heat with your silicone resin molds.
All the recommended silicone resin molds in our lists are nonstick masters! You will not have to deal with the annoyance of peeling off bits and pieces of product stubbornly stuck to the surface. This brings us to our next point: cleaning your resin molds.
Easy to Clean
If like us, you hate cleaning, silicone molds are going to be your best friend.
The ease with which you can clean a silicone mold used for resin casting is just one of many great benefits. You do not have to waste time and energy laboring away, scrubbing your molds. Wait for the epoxy resin to fully cure, then pick out the leftover pieces of resin from your mold.
If there are stubborn pieces, spray a mixture of warm water and isopropyl alcohol into the mold and wipe them out with a washcloth or thick paper towel. We recommend doing this before each new casting anyway, to make sure you don’t transfer any pigments from a previous casting into a new casting.
All the molds listed below are easy to clean and require little effort to peel off the cured epoxy resin.
Reasonably Priced and Affordable
You do not have to make a huge dent in your savings to get an affordable and yet good-quality silicone resin mold.
This is not to say that you should go ahead and buy a cheap product that lasts you a couple of uses until it gives up on you. We recommend not to go for products that are priced extremely low as they may lack in quality. However, the list we have curated offers you the best silicone resin molds while still being relatively reasonable in their pricing.
If pricing is important for you, a good practice is to be on the lookout for a sale and get a good quality silicone mold for cheaper at a discounted price. Amazon offers sales all the time. Be sure to check the prices on the molds you like, using our links below!
For this list, another factor is: BEING AWESOME, UNIQUE, and JUST PLAIN COOL.
This one is self-explanatory and not included in our silicone spoon charts. This is because each of the recommendations for silicone molds ranked off the charts in this category!!
Silicone Mold Care
How to Clean Silicone Molds
Cleaning silicone molds used for resin casting is simple, as epoxy resin does not stick to silicone. However, you must have the patience to let your casting cure completely before demolding in order to properly remove excess resin from the mold. Once a cured casting is demolded, any resin that is still stuck to the mold peels easily off the mold. Using a paper towel or magic eraser soaked in warm water to wipe away stubborn epoxy out of your mold works well. If you are still having trouble getting the excess epoxy pieces out of your silicone mold, use a bit of isopropyl alcohol on a washcloth and wipe down the mold. That should do it.
If you have not used a mold for a while, be sure to wipe out the mold with warm water or isopropyl alcohol and a paper towel before doing a new resin casting. Molds that have been stored for a while tend to pick up dust easily so you want to make sure you have wiped them down really well before using them again. Do not use any harsh chemicals like Bleach or Clorox sprays on your mold. It may ruin the surface of your silicone mold and it may become dull or rip when demolding your next casting. For these same reasons, never use abrasive sponges or steel wool to scrub your molds.
Preparing Silicone Molds for a Resin Casting
Always use a mold release before casting. A mold release is a non-stick coating, like Pam for baking sheets, that makes the silicone surface slippery when sprayed. Spraying mold release in your silicone molds before pouring your resin gives a resin artist a couple of advantages. First, the mold release makes it easier to demold your castings, ensuring your mold does not rip if you struggle to pull out the casting. Secondly, mold release protects your silicone mold from the heat created during the curing process. This helps keeps your molds in great shape for a longer time.
We recommend the following mold release agent:
Storing Silicone Molds
Storing silicone molds is not too difficult, however, you should take some time to designate a space for your molds specifically. It is not a great idea to toss your molds in a basket, one on top of the other, in an unorganized fashion. Silicone molds have the tendency to lose their shape if not stored flat. Therefore, be sure your mold is not stored in such a way that it is bending out of shape. It is a good idea to put pieces of cardboard between molds if you plan on stacking them. This keeps your molds flat and separated from one another Also, try to store your molds in a closed container so dust cannot get into the molds. Silicone seems to attract dust and this makes them harder to clean when you take them out to use again,
Obviously, all silicone molds are eventually perishable. However, you can get much use out of a mold if you wash it correctly, use a mold release agent when casting, and store your mold properly.
