From Pathfinder Wiki
For a two layer casting, fill the mold with resin to the half way point. Then let the resin cure for about 25 minutes so that it forms a gel. You may probe the resin with a craft stick to make sure it's the right consistency, but do not use your finger for this. Doing so risks spoiling the resin.
