I bought some of this stuff a few years ago and used it only a few
times, as I have access to other casting equiptment. It seems to work
fine for simple rings, gears, keys, ect. I say a demo from the guy who
markets this stuff, he is in europe someplace, and he was casting all
kinds of stuff, silver, 14k, 24k even stuff thathad a little
undercutting. He made his masters from plastic, then cast them. Their was
a woman in Massachusets that was selling it for him in the US. I think
her name is Hannah Agee? She was or is a member of the Mass Metals Guild.
Hope this helps,
