Is it from a food store or a hardware store? The dough is sitting directly on be steel (is it graded "food safe"? Steel coatings?)
Neither. It's from a metal shop. The guy cut it for me!
It is solid steel. a36 hot roll.
a36 is the type of steel, also called "mild." It is the type used generally for food preparation items such as griddles and pots or pans.
I soaked it in vinegar to remove the "mill scale" but I didn't get it all off, so I stuck it in self clean to burn it all off. I heard that works. Then I'll season it.
