Can you use baking molds for resin? If so, I’ve got some good news and bad news. The good news is, yes, you can start using your baking tools as long as they are made from metal.
Baking molds are really useful because they come in a wide range of shapes: from unicorns to butterflies, from dinosaurs to ducks!
What kind of molds can you use for resin?
We’re assuming you’re already familiar with the basics of resin casting: mixing the liquids and letting them dry, etc. If you need a refresher, we recommend going over our resin casting guide first.
In general, you can use flexible, non-porous molds for resin. This includes soft silicone molds, food grade silicone molds, plastic molds (like disposable cups), and even paper craft punches. You can also cast into metal molds like jewelry-grade pewter charms or charms made from metal clay.
There are some materials that are not compatible with resin: wood, clay (including ceramic), cardboard or paper (with the exception of craft punches). Resin will warp these materials as it cures.
Can you cast resin in silicone baking molds?
Yes, you can. Silicone is one of the most popular materials for making molds for casting resin because it’s flexible and easy to work with. But before you pull out that old silicone baking pan, read on to make sure your mold will work with resin and learn how to prepare it if it will.
Can I use cookie mold for resin?
Well, that depends on the material the cookie mold is made from and how it was made.
That’s because some molds are only food grade, others are not food grade, and some are designed for resin casting.
But don’t worry! It is possible to use a cookie mold for resin. You just need to be aware of a few things before doing so.
Can you bake resin molds?
One of the most asked questions we receive is whether or not you can bake resin molds. The answer is no, you can’t bake resin in a baking mold.
Baking molds are usually made out of silicone and are used for baking in your oven. If you were to place resin into a baking mold and attempt to “bake” it, the heat from your oven would ruin the resin.
The only exception to this rule is if you have a very small amount of resin leftover – something that would easily fit into the palm of your hand, or something similar. This leftover resin will be fine being baked as it does not have nearly enough time to reach curing temperatures.
What material does not stick to resin?
There are several materials that don’t stick to resin, the main ones being silicone, metal, glass and wood. Non-stick molds work great for most projects but you can use distressed molds too if you follow a few extra steps. While plastic molds will almost always stick to resin even if they claim not to be sticky, I’ve found you can use them with very thin pours.
Can you use food molds for resin?
Yes, you can use most food molds for resin.
Silicone baking molds work especially well for resin, so it is a great option for beginners. The silicone molds are easy to demold, and they also come in many sizes and shapes.
Many people also use plastic food containers that moldable plastic-like plasticine or modeling clay will fit into snugly as a mold box.
If you have some modeling clay at home, then this method is super simple to try out! It’s also very handy if you want to create your own custom shape.

Can you use food silicone molds for resin?
A lot of crafters will tell you that you can use food silicone molds for resin, and they are correct! A lot of people do, in fact, use food silicone molds for resin.
When it comes time to use food silicone molds for resin, however, there are a few things to keep in mind.
The first thing is: don’t use them for food anymore. Ever.
So what about new ones? New ones—ones that have never been used for food—are great! Use as many as you like! Have fun! You can also get non-food silicone molds and they work really well too.
Can you use Tupperware as a resin mold?
If you love crafting with resin, then you have probably wondered whether or not you can use Tupperware for pouring your resin. The answer is yes! However, there are a few things to keep in mind when using Tupperware as a resin mold.
Resin will stick to most plastics, but it is important to remember that the thickness of the plastic used in Tupperware and other food storage containers varies widely.
If you are planning on carefully pouring your resin into the molds, then this is not something that should be a concern.
But if you are mixing your colors directly in the molding container or mixing glitter directly into the molding container before you pour it, it will be very helpful if your molding container has thicker walls.
If your Tupperware has thin walls or is made from soft plastic, it may not last through many uses before becoming distorted and unusable for any purpose.
It’s also important to make sure that any lid you use with your Tupperware molds fits well and comes off easily once dry without warping the edges of your piece.
Lastly, avoid using molded plastic containers with lots of grooves or ridges as they tend to trap bubbles against them so they cannot rise to the top during curing.
What does casting resin not stick to?
There are a lot of ways to cast resin, and you may already have some of the molds you need hiding in your kitchen cabinets. If you’re wondering if you can use baking molds for resin casting, we have good news: it just might work!
Here are some common materials that casting resin will not stick to:
- Wax paper
- Parchment paper
- Silicone (if the silicone has been cured with a platinum catalyst)
- Heat-resistant glass—Pyrex measuring cups or bowls work great! Resin won’t stick unless they get really hot (over 200°F).
Here are some common materials that casting resin will stick to:
- Aluminum foil—the best way to use aluminum foil is with a mold release spray. Cleaning up is easy, too. Simply fold up the aluminum foil and toss it out when your project is done.
- Wax—Any kind of wax can be used for making molds, but keep in mind that larger projects may be heavy and difficult to remove from a wax mold. You’ll also want to make sure your mold is really smooth so no wax will transfer onto your finished piece. You could also try melting crayons on parchment paper, then mixing them with poured paraffin wax or beeswax while they’re still warm (not hot). Be careful transferring this mixture into another container as it could leave streaks or marks if it drips onto surfaces below where you pour. It may take several layers of coating with this method before getting a smooth enough surface for creating molds of items such as buttons and beads due to the lumpiness of the melted crayons, but it’s been done!
- Plastic—It’s best not to use any plastic that is porous because resin may soak into these plastics over time and eventually bond with them even after using mold release spray. Smooth plastics are recommended so whatever
How do you pour resin without mold?
Yes, you can use baking molds for resin. You can also use silicone muffin liners, silicone ice cube trays, food storage containers, and plastic beakers.
These items all work well as resin molds because they are flexible and so the resin will release easily after it has cured.
There are some items you should not use as resin casting molds. This includes plastic cups or other things that are not flexible – the resin will stick to these and break when removed from the mold.
Also, do not use paper or cardboard items to make a mold for your resin project – these materials can’t withstand the heat of hardening resin.
