Look what happens to Copper !
I have a roll of thin copper used for copper punch. (It's 36 gauge ) Had it for years - never used it till now. I saw this online and I wanted to make it - complete with all the rainbow colors.
I used a small torch & experimented.
Check it out !!
This pic shows the results .
*Low heat will make it turn red
*Medium heat will turn it blue.
*Next - I I used High Heat & I think there must have been something oily on the copper - it kinda did a blobbly rainbow. ( happy accident ! )
*The last one -- I blasted it -- and it turned sliver.
Cool !!!!! You can buy the tooling foil at Michaels -
I also saw it in silver tone ,too. Now this could open up whole new possibilities ! It would also be great for the leaves on wind spinners........
