Is heating copper a chem/phys change

[From: ] [author: ] [Date: 11-11-07] [Hit: ]
......
When I heated copper, a black scale type substance appeared on the copper sheet metal. Would this be a chemical or physical change? Also, what would happen if I were to heat and scrape the black stuff off the Cu over and over again?

Heating- physical
Burning -chemical

You probably burned it.
