On a conventional oven...?!
That's the broiler. It's for cooking something you want to have right under the burner so it gets really hot.
"The piece you an pull ou."
I am guessing you are talking about the storage drawer at the bottom, separate from the actual oven?? I use mine to store baking pans and lids.
cooking dead bodies.
if it gas it is a broiler
my electric stove it is just storage
