Making resin casts is a creative and popular craft project that can be done at home. A resin cast is formed when resin and a chemical catalyst are combined to form a hard, plastic-like material. These casts can be customised by pouring resin into moulds, adding colours and embedding tokens. Resin cast supplies can be found at local hobby and craft stores as well as through many online retailers.

Things you need
- Catalyst (hardener)
- Wooden mixing sticks
- Paper cups
- Mold release spray
- Eye dropper
Place the moulds you'll be casting on a flat, covered surface. Spray the inside of the moulds with the mould release spray in the same manner that you would spray non-stick spray in a muffin tin. The mould release spray will allow the resin to be easily removed from the the mould once it's done curing.
Mix the resin and catalyst together in a paper cup according to the manufacturer's instructions. An eye dropper may be needed for adding the catalyst. Follow the mixing ratios closely since the resin will not cure properly if the ratios are incorrect.
Use a wooden stick to stir the resin thoroughly. Continue to stir the resin until it is a thick consistency. Stir the resin in a manner that eliminates as many air pockets as possible as these will be visible in the finished cast.
Slowly pour the resin into the mould until it is full. To make a cast with more than one layer, fill the mould halfway and allow it to set until it is no longer sticky when touched with a wooden stick. Then mix another batch of resin and pour it on top until the mould is full.
Allow the resin to cure in the mould for a minimum of 24 hours. Gently remove the completed cast from the mould.
Tips and warnings
- Purchase coloured dyes and resin bases to customise the cast.
- Place objects and trinkets in between layers of the cast for a decorative effect.
- Resin is highly flammable. Keep it away from heat.
- Wear a respirator mask, gloves and safety glasses when using resin.
- Clean moulds thoroughly to avoid imperfections in the casts.
