The epoxy resin comes in two parts (A and B) that begin hardening about 30 to 40 minutes after being mixed together. Getting a consistent color with the pigment mixed into part B before combining the two parts made it much easier to get a consistent color throughout the mix. Epoxy resin loves bonding to things, so you need to get something that it won't stick to. I used a plastic cutting board as the base to do the initial test pours on. It worked okay, but was a bit tough to get things off. I tried again using melamine board with a coat of vaseline, which worked much better. Melamine board is used for storage shelving and can be found at most big hardware stores.
