THAT'SA LOT OF QUESTIONS. I ALSO WOULD LIKE THE ANSWERS TO SOME OF THESE. I THINK THE SHEETS WOULD SOLDER OK LIKE USING SWEATING.

Your first question about solder - that I am not too sure of since I do all my fountains with an Oxygen Acetylene torch and use silver solder or Sil Flos.

Yes, you can anneal a piece of 12" x 12" copper with a small propane torch. It will take some time, but it can be done.

When you fold or bend or hammer copper the molecules move together until they are so tight the copper fractures. Annealing releases the molecules and the copper is again soft.

You'll want to stop before you reach this point. When the copper gets too hard to form by hand it is time to anneal. To be on the safe side, anneal often.

When you heat copper a firescale (discoloration) developes. It is not necessary to remove this firescale if you like that appearaance. You can also wire brush the copper and then color it with the propane flame bringing out reds, blues and greens.

Copper is one of the easiest metals to work with. If you anneal often, it can be shaped and reshaped over and over again.
