Hi
I use a clear polyester casting resin with a catalyst they sell at Micheals and Joann's . I have made several energy pucks out of fiberglass resin that is not clear and filled it with herkimer crystals and various metals that I have buried in our gardens and yard since the are less attractive persay ;) I got the pyramid molds off of ebay and the rest are literally shot glasses , martini glasses, and different shaped random cups I found at a thrift store. The necklace pieces I made out of a easter egg plastic holder I got at a dollar store. I think ebay and amazon is the best place to get everything even the resins because I have found I can get it cheaper on there. I also try to look for the free shipping one ha ha! It's really fun when your creation is finally dry =) Friends think I am a weirdo when they come into my house ha ha I have them everywhere but they have to admit my house is a vortex of good energy lol. Goodluck
