How does the metal of a baking sheet get burned? My kid wanted to boil a kettle of water on the back burner.
An empty baking sheet was sitting on the front (we had baked some cookies earlier).
They accidentally turned on the front burner instead of the back, and walked away for a minute.
How does a baking sheet itself get burnt? Are stove tops a lot hotter than 500 degrees?
A natural gas flame is about 1950 C or 3540 F, so yes, a lot hotter than 500 degrees. (source)
Electric stoves will get red hot, indicating a temperature in the range of about 500-900 C or 770-1220 F. (source)
