Some years ago, I tried wrapping a small jar with copper wire.
I dutifully placed the piece on a set tile to guard against any drips on the kiln shelf. I used very thin wire.......This came out of the kiln.
I loved the result of the wire melt. Fortunately, it didn't drip too much and there was no sticking to the shelf.
I couldn't get the lid off.
I even bought a Dremel diamond bit. But to no avail.
It makes a nice paperweight. Or doorstop.
I must try it again, but the next time, design a catchment for the copper pooling.
Of course, if you ever wanted to seal something up permanently, this would be just the ticket.
