Copper and ferric chloride
Posted: Sun Jul 14, 2013 11:40 pm
I've been casting plates to a thickness of 1 inch with an inclusion of thin copper cut outs that have been etched with
ferric chloride. The plates have broken and refused in the first firing or in subsequent drop ring firings have either ripped
and stayed curiously intact or fractured. There are issues with off gassing through the casting. That's not the issue it
may seem as the castings are laid out so that air can escape during the cast firing. Have any of you had experience
with doing inclusions with copper etched with ferric chloride?
