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?

Many Thanks!

I got it with the intention of using it to band citrus trees to keep snails off them. Still working on that ;-).

You can get small sheets of sheet copper at Orchard Supply Hardware. It's not cheap.

I know this is an old thread, but I have been trying to make sense of all the various ways copper sheeting is referred (want to use some for snail/slug barriers as well--5 mil or 36 gauge seems to work the best and be most affordable) and came across a really good thickness guide on basiccopper.com
