Re: Oven Metal
I've read (not only in this forum) that heating galvanized metal might be a bad idea, but no one's been specific on what temperature would be "safe". I know that welding gal. puts off dangerous fumes but that would be extremely hot, way more than 500 degrees. Any thoughts on this because I am also wanting to use gal. if it will not be a health hazard or cause contamination problems with my parts below 500-600 degrees.

Re: Oven Metal
Our oven is sheathed inside and out with 20 gauge galvanized, no problems or toxic fumes. I did a burn off at 400 for an hour to make sure, works great for us. The main thing is the air circulation for hot/cold spots. Other then that galvanized is fine, alot of larger ovens are built using the same material.
