Moulding Compound 1 oz

This easy, quick and safe to use Rio Cold-Mold two-part silicone moulding compound is fantastic for creating moulds which you can use again and again for making metal clay jewellery.

Moulds can be created from shells, fossils, buttons and anything else you can think of, you can also create your own flat texture sheets capturing textures from lace, fabric, tree bark or leaves. 

How to use: Simply mix equal parts of the pink and white compound together to activate, impress the item you are creating a mould from and allow it to harden for approximately 10-15 minutes.
