Casting resin’s curing process is caused when heat is generated by the chemical reaction that takes place when catalyst is added to casting resin. Keep this in mind when reading through this bulletin and working with Castin’Craft Casting Resin.
I would also strongly advice you to read the Castin’ Craft Idea book which is available free online.
Remember, due to the nature of casting resin, consistent results are obtained through attention to detail. Never place one of a kind objects in casting resin, because once in, it is almost impossible to remove. Always practice before doing your final piece. Start small and work up to larger items so you can become comfortable when working with casting resin.
