Castin’ Craft Clear Casting Resin is a polyester resin for casting paper weights, trophies, chess sets and conversation pieces. It’s also great for embedding coins, dried flowers, biological specimens, and minerals in clear plastic. You can even add transparent dye or opaque pigment to achieve custom results.

Castin’ Craft Clear Casting Resin Catalyst is sold separately. The catalyst MUST be combined with the casting resin for any hardening to take effect.

The following is a guide to the recommended ratios for use of casting catalyst with clear casting resin:

Formula for one layer casting: if layer is 1/8 in. thick use 15 drops per ounce of resin. If layer is 1/4 in. thick use eight drops per ounce. If layer is 1/2 in. thick use six drops per ounce. If layer is 3/4 in. thick use five drops per ounce. If layer is 1 to 1 1/2 in. thick use four drops per ounce.

For multi layer projects (especially when embeddingitems into it): first layer use five drops per ounce, for the second layer use four drops per ounce, for the third layer use three drops per ounce and for additional layers use two drops per ounce.
