Preparing to cast my carved limestone MoonSnail.  I think this mold is better, but I should reinforce the rigid mothermold: it is too thin on the sides!  I have even remember to measure the volume I will need (3 cups) today, so the mold will be really dry tomorrow. I do plan to experiment a bit though:  I can’t resist. I will mix two fillers plus pigment in my clear two part epoxy resin, and see what happens.  I am hoping it will be opaque, or almost, and a bit stronger (due to chopped carbon fibers as one of the fillers).
