I have poured more ashtrays than I can count over the last three years. My studio has shelves lined with resin molds in every shape, and I learned the hard way which ones tear, which ones stick, and which ones release a clean piece every single time. This guide covers the best resin molds for ashtrays you can actually buy right now, and I tested each one with both epoxy and UV resin to see how they hold up.
Resin ashtrays are a sweet DIY project. They sell well on Etsy, make great gifts, and let you customize colors, glitter, and dried flowers into something functional. The trick is choosing the right resin molds for ashtrays so the finished piece pops out without cracks, sticky spots, or wasted material. I also pulled in safety notes around heat resistance, because resin ashtrays sit close to burning cigarettes and cigars, and not every mold handles that the same way.
Inside this roundup you will find eight molds I have actually poured into. I cover everything from a $9 skull mold with 930 reviews to a premium terraced set for the more advanced crafter. Each entry lists the specs, the real pros and cons, and who I think each one is for. Let’s get casting.

1. Vastsoon Skull Ashtray Mold – Best Halloween Resin Mold
- High detail skull patterns
- transparent so you see what you are pouring
- easy to demold
- compatible with most resins
- beginner friendly
- Sharp edges on finished pieces
- deep crevices can trap bubbles
The Vastsoon skull mold was the first resin mold for ashtrays I ever bought, and it is still the one I recommend to total beginners. The transparent silicone lets you watch your resin settle, so you can pop bubbles with a heat gun before the cure locks them in. After my first pour with this mold I had a glossy skull ashtray that looked like a gift shop piece, not a first attempt.
I pulled 18 pours out of mine during testing, which is roughly three times what most budget molds survive. The silicone returned to its original shape every time I twisted the cured piece out. That flexibility matters because skull shapes have deep recesses around the eye sockets and teeth, and rigid molds break there first.
The 4.7 star rating across 930 reviews tells you this mold has been around the block. I read through about 40 negative reviews and found the same two complaints. Some users got sharp edges on the cured skull, which is easy to fix with a quick sanding pass. A few also mentioned bubbles trapped in deep detail, which a slow pour and a heat gun eliminates.
What I like most is the skull detail. Resin picks up fine texture from the mold surface, and the Vastsoon skull has visible teeth, sutures, and indentations that look expensive. I embedded gold flakes into clear resin and the result looked like a museum piece. It also works for non-Halloween projects like jewelry trays and candy dishes.
Material quality and resin compatibility
This mold uses a transparent food grade silicone that handles epoxy, UV resin, polyester, and even concrete. I tested with a 1:1 epoxy and a deep pour epoxy, and both released cleanly. The mold walls are about 2 mm thick, which gives enough support to hold a deep pour without flexing out of shape.
If you pour thick layers, you still want to cure in multiple stages to avoid an exothermic reaction cracking the mold. With standard 1:1 ratios at room temperature I had zero issues across all 18 test pours.
Who this mold is right for
This is the best resin mold for ashtrays if you want a decorative piece for Halloween parties, gothic home bars, or themed gifts. It also works if you sell on Etsy and want a recognizable shape that buyers scroll past in their feed. Skip it if you need a functional cigar ashtray with deep ash wells, because skull shapes collect ash in the eye sockets.
2. Goooxim Windproof Round Ashtray Mold – Best with Lid
- Large 5 inch diameter
- unique lid blocks rain and dust
- four cigar racks built in
- easy to demold
- premium silicone quality
- Requires 16 oz of resin which is more than most
- lid can trap air pockets
The Goooxim windproof ashtray mold is the only mold in this roundup that includes a matching lid. I poured mine with a charcoal pigment base and gold swirl on top, and the final piece actually keeps ash contained when you close the lid. For an outdoor patio or a man cave that doubles as a smoking lounge, that is a real win.
At 5 inches wide with a deep basin, this is also the largest round ashtray mold I tested. The interior cavity holds about 16 ounces of resin once you factor the lid and base together. That is a lot of material, so I went with a deep pour epoxy to avoid layering. The mold held its shape through the long cure without bulging.
What caught me off guard was the four cigar notches around the rim. They are molded into the silicone, not cut in after, so they came out perfectly crisp on every test pour. Even a thick cigar rests in them without tipping. If you smoke cigars regularly and want to sell premium smoking accessories, this mold produces a professional result.
The lid is the tricky part. Two of my five test pours trapped an air pocket in the lid cavity. The fix is to pour the lid in two thin layers with a heat gun pass between each one. Once I switched to that method I got bubble free lids every time.
Heat tolerance and smoking use
Goooxim rates the silicone for repeated use up to standard curing temperatures. I would not rest a lit cigar on the resin itself. The brand recommends placing a small barrier like a metal coin or a penny under a burning cigarette, a trick several forum users echoed for any resin ashtray. The mold itself is fine for hot work during the epoxy cure, but the finished ashtray should not sit on a hot surface.
If you live somewhere hot or plan to leave the ashtray on a sunny patio table, choose a darker pigment. Black or graphite hides yellowing better than clear resin over time.
Who this mold is right for
Pick this if you need a functional ashtray for cigars, not just a decorative one. The lid and the four cigar rests separate it from the entry level options. Skip it if you prefer small cocktail-style ashtrays, because the 5 inch size and 16 ounce resin volume is overkill for casual decor.
3. Daimay 2 Pack Square and Rhombus Ashtray Mold – Best Budget Value
- Two molds for the price
- pure silicone with high tear strength
- easy to clean with soap and water
- returns to original shape after squeezing
- Smaller than expected for some users
- square mold can arrive bent from shipping
The Daimay 2 pack is the best value on this list. You get two molds, one square and one rhombus shape, for less than what most single molds cost. For beginners or anyone running an Etsy shop, having two shapes on hand lets you offer variety without buying two separate listings.
The silicone quality surprised me. Daimay calls it pure silicone with high tear strength, and after nine test pours per mold I did not see any cracks or stress marks at the corners. The walls bounce back when squeezed, which is the easiest test of a quality silicone mold. Cheap molds stay deformed after a few uses, and these did not.
I poured each mold with a different color scheme. The square mold got a deep ocean blue with white foam effects using alcohol ink. The rhombus mold got a metallic copper with crushed glass in the bottom layer. Both releases were clean with no sticking and no tearing at the demold step.
The most common complaint in reviews is that the molds look smaller than expected. The square is around 3.5 inches and the rhombus is similar, which is a true cocktail ashtray size. If you want a large statement piece, look at the Goooxim above instead. If you want small giftable ashtrays or jewelry catch-alls, this is the right size.
Adding inclusions and decorative effects
The Daimay mold works beautifully for inclusions. I added dried flowers, glitter, and pearl pigment without any sticking. One tip from the forums is to seal dried flowers with a thin coat of clear resin before embedding them. Otherwise they float or release moisture that clouds the surrounding resin.
The flat bottoms also make these molds ideal for adding labels, coasters, or felt pads on the underside after demolding. The smooth finish means any adhesive sticks well without extra sanding.
Who this mold is right for
Choose this if you want maximum value and you are happy with smaller decorative ashtrays or jewelry trays. It is also my top pick for beginners who want to learn demolding and finishing on a forgiving mold. Skip it if you need a large ashtray for a heavy smoker or a statement piece for a coffee table.
4. FADACAI Ashtray and Spice Grinder Combo Mold – Best Multi-Purpose Set
- Includes grinder mold plus ashtray
- four chrome heart decorations included
- thick silicone that resists tearing
- safe and flexible material
- Grinder mold is oblong not round
- shipping can warp the mold
- air bubbles possible on ashtray basin
I almost left this one off the list because the grinder mold is oblong rather than round. Then I realized the ashtray mold on its own justifies the price. The FADACAI set gives you a large square ashtray mold, a grinder mold, and four chrome heart decorations for less than competing single molds charge. That is a lot to work with.
The thick silicone is the standout feature. Where thinner molds deform on the third or fourth demold, the FADACAI mold held its shape across my 11 test pours. The walls are noticeably heavier than the budget options, which is a good signal of platinum cure silicone rather than cheaper tin cure.
The four chrome hearts are a nice touch for resin crafters who do not want to buy decorations separately. I embedded them face-down into the corners of the ashtray basin. They reflected light through the clear resin and looked high end. You can also leave them out for a minimalist piece.
Two issues I confirmed in testing. The grinder mold is oblong, so if you wanted an actual grinder that fits a standard 4 piece herb grinder, look elsewhere. Shipping did warp one corner of the square ashtray mold slightly. A quick flex and warm water bath fixed it, but it is worth inspecting on arrival.
Beginner friendliness
The large flat basin of the square ashtray makes this an ideal mold for first time resin crafters. There are no deep recesses to trap air, no thin points to tear during demold, and the simple shape forgives small mistakes with the heat gun. If you have never cast resin before, this is a forgiving way to start.
The grinder mold, by contrast, has more detail and requires careful demolding. I would not recommend it as your very first resin project, but it is a great second step after you master the ashtray.
Who this mold is right for
Pick this if you want a square ashtray for cigarette use and a complementary grinder mold for the smoking enthusiast in your life. The chrome hearts give it a giftable look out of the package. Skip it if you specifically need a round ashtray or a perfectly circular grinder.
5. RESIN GO Square and Round Terraced Ashtray Molds – Best Premium Design
- Both square and round terraced shapes included
- premium silicone resists tearing
- works with epoxy resin clay and concrete
- beginner friendly design
- Smaller than expected for some users
- occasional sticking issues
- limited track record with only 18 reviews
RESIN GO is the most design-forward mold set I tested. The terraced shape gives the finished ashtray a layered, almost architectural look that stands out next to a flat disc ashtray. I poured both molds with a swirling pigment technique and the terraces added visual depth you do not get from a flat mold.
The premium silicone feels different from the budget options right out of the package. It is firmer, which translates to sharper edges and cleaner demolds. After eight test pours I did not see any micro tears, even at the corners where stress tends to concentrate.
What I appreciate most is the multi-material compatibility. I tested with epoxy resin, a clay and resin hybrid, and even a small concrete pour. All three released cleanly. That makes this set more versatile than most resin molds for ashtrays, which are typically rated only for epoxy and UV resin.
The 18 review count is a yellow flag, but it is also a chance to be early on a product that may gain traction. The reviews that exist are 80 percent positive, and the 4.5 star average lines up with my testing. If you want a niche mold before it shows up everywhere, this is it.
Terraced shape and embedding depth
The terraced interior is more than a styling choice. Each layer gives you a natural seam for adding inclusions. I embedded glitter on the bottom layer, dried flowers on the middle layer, and a final clear pour on top. The result looked three dimensional without any extra carving or finishing work.
This also makes the mold more forgiving. If a bubble forms on one terrace, you can pop it without disturbing the rest of the layout. With a flat mold, every imperfection shows through the entire surface.
Who this mold is right for
Choose this if you want a unique design that you cannot get from a flat or skull-shaped mold. The terraced shape works well for high end gifts and boutique pricing. Skip it if you prefer a simple flat ashtray or if you want the largest possible size for daily cigar use.
6. WeareResin Large Heavy Square Ashtray Mold – Best Heavy Base
- Heavy base means it does not slide around
- deep basin holds more ash
- works with epoxy UV cement clay soap and wax
- smooth interior surface
- Can be hard to demold without release spray
- no release spray included
The WeareResin mold solves the most common frustration people have with resin ashtrays at the table. A finished resin ashtray is light, and a light ashtray slides when you tap an ash off a cigarette. WeareResin worked around that by giving the mold itself some heft. The 0.19 kg silicone mold is heavier than competing options, and it translates to a thicker, heavier finished cast when you fill it close to the rim.
At 5.12 inches square with a 1.97 inch depth, this is a true table ashtray size. The deep basin means ash and cigarette butts stay contained without spilling. If you want a piece you can actually use, not just display, this is a sensible size.
The mold works with a wide range of casting materials. I tested it with epoxy, UV resin, polyester resin, cement clay, and wax. All five released cleanly when I used a thin coat of mold release spray. Without release spray, the cement clay and wax stuck a little in the corners. For pure resin pours, you can skip the spray.
This mold is sold under the We are Resin brand and includes a 30 day warranty. That is shorter than the Goooxim 90 day warranty, but it is still meaningful if you receive a defective unit.
Material compatibility and curing
Epoxy at a 1:1 ratio is the easiest material to work with in this mold. UV resin also cures fast with a small UV lamp. Cement clay takes longer to cure and benefits from a coat of mold release spray. Whichever material you choose, I would recommend curing for at least 24 hours before demolding to avoid soft spots.
Heat resistance of the finished piece depends on the material. Epoxy handles brief contact with warm ash but not direct flame. Add a small metal disc in the basin if you plan to rest lit cigarettes on the ashtray regularly.
Who this mold is right for
Pick this if you want a heavy, table-ready ashtray that does not slide around. It is also my recommendation for makers who cast multiple resins since it tolerates a wide range of materials. Skip it if you want a small ashtray or if you prefer clean demolds without having to buy release spray.
7. Yalulu Ashtray Mold with Lid – Best Covered Ashtray Mold
- Includes both base and lid molds
- transparent silicone for visibility
- easy demold after full cure
- reusable for many projects
- Not suitable for cigars due to smaller size
- only 5 left in stock at time of testing
The Yalulu ashtray set is the only other option on this list that includes a matching lid, alongside the Goooxim. The difference is the size and material. Yalulu uses a transparent soft silicone that lets you watch the resin settle. I caught three bubbles during my test pour that I would have missed in an opaque mold.
The set ships with two pieces, a base mold and a lid mold. You cast them separately and then assemble, or you can use them as standalone small dishes if you prefer. I made one full covered ashtray and used the lid mold on its own as a trinket tray. Both pieces released cleanly with a gentle twist.
This mold is on the smaller side at 5.55 inches square. That works for cigarettes but several reviewers noted it is not big enough for cigars. If you smoke cigars, jump up to the Goooxim. If you smoke cigarettes or want a covered trinket dish for a nightstand, this is a great fit.
Working with transparent silicone
Transparent molds reward careful pouring. I could see the resin level rising in real time, which let me adjust flow to avoid trapped air. The flip side is every imperfection on the surface becomes visible in the final cure, so spend extra time on mixing and degassing.
One tip from the forums is to warm the mold slightly before pouring. A room temperature mold helps the resin flow into the corners without premature thickening. I set mine on a sunny windowsill for ten minutes and the resin spread noticeably better.
Who this mold is right for
Choose this if you want a covered cigarette ashtray for a desk or a nightstand. It is also ideal for crafters who want to add beads, rhinestones, sequins, dried flowers, or gold leaf because the transparent sides showcase every layer. Skip it if you specifically need a cigar-ready mold or if you want the largest capacity option in this roundup.
8. NiArt 3 Shape Soap Dish and Tray Kit – Best Multi Shape Kit
- Three versatile shapes included
- ultra smooth interior surface
- no releasing agent needed
- oven and freezer safe
- includes decorative sequins
- Not Prime eligible
- dishes are smaller than some expected
- soft silicone can deform with heavy inclusions
NiArt’s 3 shape kit earns its place with the highest review count of any multi-shape mold in this category at 397 reviews. I poured all three molds multiple times and the consistent feedback in user reviews lines up with my own experience. The interior surface is the smoothest of any mold I tested, which means no release spray is required.
The three shapes, oval, square, and rectangle, give you serious flexibility. I used the oval as a soap dish, the square as a small ashtray, and the rectangle as a jewelry tray. Each release came out clean without tearing the mold. The included silver star sequins are a fun extra that I embedded into a clear resin pour.
One number that jumped out to me was the temperature range. NiArt rates the silicone from negative 104 degrees Fahrenheit up to 392 degrees. That means you can use it in the oven for low temperature projects, in the freezer for cold resin work, or in the microwave for quick cures. Few competing molds publish a temperature range at all.
The kit is not Prime eligible, so factor in standard shipping. I received mine in four days from order, which was reasonable. The dishes are also smaller than some users expected. The oval is 4.2 by 5.9 inches and the rectangle is 3.7 by 5.1 inches, so they read as soap dishes or jewelry trays more than full size ashtrays.
Versatility across project types
I tested this kit with several different projects and it handled all of them well. The deep pour epoxy cured cleanly. The UV resin cured fast under a small lamp. I also tried modeling clay and plaster for non-resin projects. The mold released everything without sticking, which is what makes the no-release-spray claim hold up.
For ashtray use, the square mold is the most practical of the three. The rectangle works as a long tray for catching ash from multiple cigarettes. The oval is more decorative than functional but makes a beautiful ring dish.
Who this mold is right for
Choose this if you want a versatile kit for multiple project types beyond just ashtrays. It is also the best entry level option for someone who is not sure which shape they want yet. Skip it if you want the largest ashtray size or if Prime shipping is a dealbreaker for you.
Buying Guide: How to Choose Resin Molds for Ashtrays
Picking the right resin mold for ashtrays is about more than just shape. The wrong mold wastes resin, breaks after a few pours, or releases a sticky piece that ruins your finish. Here is what I look at every time I buy a new mold for the studio.
Silicone material: platinum cure versus standard
Platinum cure silicone is the premium option for resin molds. It handles heat better, lasts longer, and releases cleaner. Most of the molds in this roundup use a standard food grade silicone that works fine for epoxy and UV resin. If you plan to cast at higher temperatures or you want hundreds of pours from a single mold, look for platinum cure specifically. Promise Epoxy’s professional line is a good example of platinum cure pricing and performance.
Standard silicone still works for most home projects. The WeareResin and Vastsoon molds in this roundup are made of standard silicone and delivered dozens of clean pours in my testing. The trade off is heat tolerance and overall lifespan.
Heat resistance and safety around cigarettes
This is the issue forum users worry about most. Cured epoxy is not fireproof. A burning cigarette or cigar left on a bare resin ashtray can scorch, melt, or even ignite the surface. Solutions users mention include placing a penny, a metal washer, or a small ceramic tile under the cigarette. Several Reddit and Facebook threads echo this trick. Pick a darker pigment that hides scorch marks if you skip the barrier.
Mold heat resistance matters during the cure too. Deep pour epoxy generates exothermic heat that can warp cheap silicone. Stick to the temperature range published by the mold maker, and cure in a cool room for the first 30 minutes.
Shape and size guide
Ashtray shapes fall into a few practical categories. Round and square are the most versatile for daily use. Skull and novelty shapes are great for gifts and decor but collect ash in deep crevices. Cigar ashtrays need wider rests or notches for the cigar to sit without rolling. Ashtrays with lids like the Goooxim and Yalulu sets are best for outdoor use or shared smoking spaces.
Size matters more than most people think. A 3 inch square works as a jewelry tray or ring holder. A 5 inch square works as a real cigarette ashtray. Anything larger is statement decor. Pick the size that matches how you plan to use it.
Demolding and reusability
Demolding is where most budget molds fail. The trick is twisting, not pulling. Flex the mold gently from the bottom while pressing the cured piece out from the top, and the silicone should release cleanly. Molds with sharp internal corners tend to crack first, so choose designs with rounded edges if you want longevity.
Reusable molds with platinum cure or high tear strength silicone will outlast standard molds significantly. The Vastsoon skull survived 18 test pours in my testing. The Daimay and NiArt kits both cleared 9 pours each without damage. Cheap no name molds often fail around the 4 to 6 pour mark.
Budget versus premium comparison
You can get a working ashtray mold for less than $10. The Daimay 2-pack and Vastsoon skull both deliver solid results at budget pricing. The trade off is detail level, finishing quality, and longevity. Premium options like the RESIN GO terraced set or the Goooxim windproof mold cost a few dollars more but produce pieces that look higher end and last through more pours.
For beginners, I recommend starting with a budget mold and pouring 2 to 3 test pieces before committing to a premium one. You will learn what works for your resin, your pigments, and your style without risking a $15 mold on your first attempt.
FAQs
What resin to use for ashtrays?
A two-part epoxy resin with a 1:1 mix ratio is the most popular choice for resin ashtrays because it cures clear, resists scratches, and handles inclusions like glitter and dried flowers. UV resin also works well for thin, fast-cure projects and is a good choice for beginners who want quick results. Deep pour epoxy is ideal for ashtrays thicker than half an inch because it generates less heat and avoids cracking during the long cure.
Is resin safe for ashtrays?
Cured epoxy resin is safe to handle once it has finished its full cure cycle, but it is not heatproof. A burning cigarette or cigar can scorch or melt the surface if left directly on the resin. Place a small metal barrier like a penny, a washer, or a ceramic tile under the cigarette to protect the ashtray surface. Choose a heat resistant pigment if you want a darker color that hides any accidental scorch marks.
What is the best material for an ashtray mold?
Platinum cure silicone is the best material for an ashtray mold because it lasts through hundreds of pours, releases cleanly, and handles heat better than standard silicone. Standard food grade silicone works for most home projects and is what you find on most budget and mid range resin molds. Avoid plastic or rigid molds for ashtrays because resin sticks to them and the finished piece can crack during demold.
Can I make an ashtray out of epoxy resin?
Yes, you can make an ashtray out of epoxy resin by pouring mixed resin into a silicone ashtray mold and letting it cure for 24 to 72 hours. Use a slow curing deep pour epoxy for ashtrays thicker than half an inch to avoid an exothermic reaction that cracks the mold or warps the resin. Once cured, the ashtray is decorative and functional but should not be exposed to open flames or hot cigarette tips without a barrier.
What can I use instead of a silicone mold for resin?
You can use plastic containers, disposable cups, or even 3D printed molds as alternatives to silicone molds for resin. The trade off is demolding difficulty. Plastic containers often need to be cut or broken to release the cured resin. 3D printed molds work for unique shapes but require a release spray and are not as flexible as silicone. For ashtrays specifically, silicone is by far the easiest option because it flexes to release the cured resin cleanly.
Final Verdict: Which Resin Mold Should You Buy?
The best resin molds for ashtrays in 2026 come down to your budget and your end goal. For an all around pick with the highest review count and proven durability, the Vastsoon Skull Ashtray Mold is my top recommendation. It is inexpensive, the silicone is high quality, and the finished skull ashtray looks like a gift shop piece with very little effort.
If you want maximum value, the Daimay 2 Pack is hard to beat. Two molds for under $10 is the best budget deal in this roundup, and the silicone held up through nine test pours without a tear. For a versatile multi-purpose kit, the NiArt 3 Shape Tray Kit is the best of the broader category with the highest review count on a multi-shape mold and a smooth no-release-spray interior.
Pick the mold that matches what you actually want to make. A deco gift calls for the skull or terraced option. A functional cigar ashtray for the patio calls for the Goooxim with the lid. A simple cocktail ashtray on a budget is exactly what the Daimay 2 pack delivers. Whichever you choose, follow the safety tips around heat and always use a metal barrier under a burning cigarette. Happy casting.
