About 3 weeks ago, I attempted to wash my cup in boiling water in a pot on the stove. I then proceeded to sit down and watch tv and completely forgot about it until ~40 minutes later when the fire alarm went off: there was a small fire in the pot, in which all the water had evaporated. I threw the cup away and have ordered a new one. My question is: do you think I can still use that pot for cooking, or is it now ruined due to burned cup? It does have burn marks in the bottom.
