Resin casting moulds: where to start?
You can find a huge variety of silicone moulds on Etsy, Ebay and Amazon as well as in specialist resin shops. These are flexible and have some stretch to them, so they lend themselves to detailed designs as well as simpler ones. Because they can be stretched, they can be used for three dimensional shapes (you would be unable to extract a 3D shape from a rigid mold). It is possible to tear silicone molds so be gentle when extracting resin pieces!

Silicone molds can be either shiny or matte within the mold, and this will determine the finish on the resin you cast. If you use a silicone mold with a matte interior, your final item will be matte and dull in appearance. If you use a mold with a shiny interior, it will produce shiny items, however over time, as it is used it will gradually lose the shine.
Silicone molds have a limited lifespan and will eventually wear out. If the mold is shiny, over time it will become more matte in appearance, and will lose some of its definition on details. If there is a mold you really love, it can be worth buying an extra one to make sure you can keep working with it for longer!
When you are not using your silicone molds, store them in a container to keep dust off them and help stop them becoming damaged. You'll find that the texture of a silicone mould is a bit of a magnet for dust and lint, which is hard to get off and can spoil projects.
If you need to wash them, be very gentle not to scratch the inside of the mold cavity and leave them to fully air dry. If they have any water on them when you use them, you’ll ruin your resin project.
Plastic polypropylene or polyethylene molds
These are hard, rigid molds and are made from plastic sheets. They tend to be less detailed than silicone molds, but they are often cheaper.
Plastic molds do not always produce shiny resin pieces – they may come out dull depending on the plastic. If this is the case, you can recoat the surface with another layer of resin to make it shiny.
As they are rigid, they are only suitable for relatively flat mold shapes (more three dimensional designs would be impossible to de-mold). These molds are often used for small to medium sized cabochon shapes, where multiple shapes are part of the same mold.
More resin moulds to try
There are lots of molds available to use with epoxy resin, but if you can't find exactly what you are looking for, you can also use some molds designed for other things such as silicone baking molds or polymer clay molds. If you decide to use another type of mold for resin casting check what it is made out of before pouring resin into it - resin will adhere to some plastics and could ruin the mold making it unusable. If you use a mold designed for food, keep that just for resin use and don’t make food with it to avoid any chemical contamination.
How to make a silicone mould
If you still can’t find the mold you are looking for, you can make your own silicone mold using a kit such as this one from DecorRom (Amazon, £18.99).
