Zee, It is very wise of you to wear protective glasses. For torch
work (soldering, casting, etc.), I use didymium glasses which are
recommended for acetylene, Mapp gas, and Propane.
For kiln firing, I use Calobar glasses available from Enamelworks in
Seattle They have a website.
I don’t have a source for the Didymium glasses, as the place I got
them is no longer in business. Hopefully someone on Orchid can help
