I just had something very unexpected happen while soldering a fine
silver bezel to a sheet of sterling. The sterling was 20g and was run
thru the rolling mill once, very lightly impressing a fabric pattern
I then put the bezel, flux and solder on the sterling sheet. I
mounted the sheet on two enameling trivets so I could get the torch
underneath the sheet and heat it from the underside. The trivets
weren’t the best approach but that’s beside the point.
I applied a light pressure on the bezel wire with a soldering pick
so the bezel would maintain contact with the sheet.
As the sheet got hot it sagged a bit and shifted the bezel, hence my
comment about the trivets not being the best way to do this. (Oh! The
joys of learning.)
Here’s the surprising part. One of the corners of the sterling sheet
detached itself from the rest of the sheet. The metal along the
broken edge looks like it crumbled off (as opposed to was sheared
Huh? What is going on here? Is it bad metal? Or did I just do
something stupid that I don’t understand?
