Quenching glass

[Bert Weiss]

I did wonder about your warning not to use a galvanized bucket to quench glass since many people cook in them. From what I've heard, zinc vaporizes at around 1600 F, so heating glass to 1000-1200 then dropping it into a galvanized bucket with water in it would be nowhere near 1600F. And even if fumes were released they would dissipate into the air if you were outside (where I would be).

I am not a metallurgist, toxicologist or industrial hygenist, but common sense tells me not to heat a galvanized container to red hot in my kiln. It is not like stainless steel is a rare or terribly expensive material for bowls or containers.

Actually, I meant to heat the glass in something else in the kiln then drop it into a galvanized bucket with water in it - outside of the kiln. I never meant that the bucket itself would be in the kiln. Maybe I wasn't clear about that.

No problem. I quench in a water filled plastic bucket. It works just fine.
