High temperature molds and materials
Does anybody out there know anything about high temp. refractory molds.
When I say high temp I mean in the 1800 - 1900 F. range. I know this is well beyond the range of soft glass but I have another purpose in mind.
If anybody can help it would be greatly appreciated.
Thanx.
I would also be interested in any moldable material that could be used at the same temps.

I've used castolite. Plan on test firing before you fire a full kiln. I fired a load in which I had castolite molds, steel molds, ceramic molds and ceramic fiber molds and the glass on castolite over-fired. the other pieces were fine. My thinking is that the castolite retained the heat much longer than the other materials. Also the castolite molds were much thicker that the other molds. Good luck.
