fractures?
Ok so new to the art of jewellery making, I have 1.6mm sheet that I have cut to length and width all good. mandrel and raw hide hammered it into round, used saw to create clean ends, soldered, pickled, made sure round on ring mandrel, started to clean and noticed fractures on inside of ring. Surely I had not hit it enough to work harden? or is this a risk when working with thicker material?
Cracks/fractures were curves in shape and were radiating from edge towards centre. Material was fully annealed silver from Cookson.
