If they don't fit your needs or budget, alternative materials like plastic containers and glass containers can be used as resin moulds.
You can use your old baking silicone moulds, or anything made of silicone materials. If you don't have any you can use a hard tape to create a boundary and pour resin in it.
You can make a mold for casting epoxy resin from various materials – from steel, plastic (e.g. polypropylene, polyethylene, polycarbonate, etc.), wood, MDF boards, laminate, silicone, glass or plexiglass, etc.

Beyond resins, sculptors can explore alternative casting materials like concrete, foam, glass, and plaster. These options expand creative possibilities while introducing new considerations for environmental impact and health safety.
Resin art can be created without using silicone moulds; you can turn anything into a mould, but the condition is that epoxy resin must not possess a tendency to glue with it. Materials such as shrink wrap and cardboard, acrylic stones, sheathing tape, etc., can form mould.
Two of the more popular mold release agents are fluoropolymer based entities (such as PTFE) and polysiloxanes (silicones), although there are certainly a number of other types that are available as well. Mold release agents are typically applied by spraying on to the substrate / housing.
One of the best materials to use for molds is silicone, resin doesn't stick easily to silicone and it is very flexible, meaning that it is relatively easy to get your resin out of after it is fully cured. You can make your own silicone molds and there are lots of YouTube videos which show you how to do this.
Glass, being a high surface energy material, easily attracts resin and creates a strong bond. In contrast, low surface energy materials like plastic repel resin, which is why cured resin peels so easily from plastic tools and silicone molds.
Epoxy resin adhesives will bond with most all woods (though a primer sealer if often recommended for many types of wood to seal it). Resin does not bond to Teflon, polyethylene, polypropylene, nylon, or Mylar. It bonds poorly to polyvinyl chloride, acrylic and polycarbonate plastics.
Silicone moulds are a popular choice among resin crafters due to their ease of use and flexibility. They allow for easy demoulding and are reusable, making them a great investment. Plastic moulds, on the other hand, can be more rigid and may require more effort to remove the cured resin.
Mixing the Two Ingredient Mold
Squeeze silicone into the cornstarch. Roughly the same amount. Then add some more cornstarch on top of the silicone and mix. If you're using your hands, wear gloves.
While high-quality silicone molds can be an investment and are not always immediately available, aluminum foil is a common household item found in most kitchens. You can use just the amount you need, making it a budget-friendly option for all sorts of projects.
There are a few brands of liquid clay that cure crystal clear and glossy and can therefore make an excellent alternative to resin. Kato Liquid Polyclay, Sculpey Liquid Clear (Affiliate Links – learn more here), and Fimo Liquid will all cure clear and glossy when they're fully cured.

Glass containers, metal tins, and wooden boxes can all be used as molds. Just ensure you use a mold release agent to prevent the epoxy from sticking.
🕯️✨ The answer is YES! But the finished product might be a bit matte.
The short answer is yes, you can use disposable plastic cups as moulds for epoxy resin. These cups can be a convenient and inexpensive option for small resin projects.
Nearly anything can be used as a mold! If you're not into building your own mold from scratch, you can use alternatives such as baking pans, ice trays, or even candy molds. These come in different shapes and sizes, so they're perfect for a variety of projects.
The short answer is yes. You can absolutely use resin with polymer clay, but there are a few things you should know before you get started. It's important to understand the basics of what each material can do. Polymer clay is a type of modelling clay that hardens when baked in the oven.
Nonstick cooking spray, which can be found in most grocery stores, is a good resin mold release agent because it doesn't stick. It's safe and won't hurt the resin or the mold. Make sure to wipe the cooking spray off the resin creation and the mold with a rag when you remove it.
To release the resin from its mold, use Vaseline. Apply it over the mold before adding the epoxy resin. This mold release for epoxy prevents the resin from sticking to the mold.
WD-40 contains strong acids in order to penetrate rust. While it might not affect your skin much more than drying it out, it'll absolutely damage a mold. Its thin viscosity means it won't adhere to the sides of molds. It also contains wax.
