For copper that thick, you'll probably need to heat the area for ~15 sec at or near red hot. The copper will turn black in the area being heated, but that should not be an issue as is should clean off with a green abrasive pad. Also, do not force cool let is just cool by itself.

The same applies to other metals such as brass.

Good Luck on your next heater valve project.
