I accidentally left an empty stainless steel pot on high heat for 10 mins. It turned bronze. Is it OK to use?

Question:Obviously I'm not worried about heat conduction, I just want to make sure nothing happened on a chemical level that might make it toxic or otherwise unhealthy to keep using the pan.

Answers:
It is safe. In fact often saucepans and other kitchen utensils that are made of Stainless steel often go bronzr when exposed to levels of high heat.
Stainless steel whether silver of bronze is still the same steel so do not worry at all.
