I am about to fire two molds filled with Gaffer Casting Crystal. This is my first time using this gorgeous glass…definitely won’t be the last. So I asked Mr. Google about this and besides the Gaffer Glass web site, I noted there was information from Cynthia Morgan. I really admire Cynthia’s work and have heard from very reliable sources that her information is some of the best, so I’m looking at her blog for advice on the subject. Casting crystal is different from what I’m used to, Bullseye Glass.
