3 oz copper sheet?
I'm a total newbie. Saw some copper sheet at HD -it was rolled up with brown paper and not really obvious as copper. Just marked as roofing sheathing for wood roofs.
Anywho, it was also marked as 3 oz copper. Where does that designation come in and what does it mean? The roll must have weighed at least 8 lbs.
And, would this weight have any cool crafting qualities or is it too lightweight?
