Jewelry Design, Week 2

I learned about the process of rolling and annealing (def: reducing stress within metal by heating to a prescribed temperature).

Whenever you want to melt scraps, you use a higher temperature. However in annealing, you want to use a "feather flame" (please see diagram below), and when the medal reaches a certain glow, you cool it and pickle it. After the pickling process, the metal has to be completely dry and free from oxidation, you roll it.

Most designs either require a flat shape or cylindrical shape in order to form wire. Always roll in one direction, and about five times. If you're working with purer or softer metals, you can stretch it a little. Find the "dead pass" (just a little resistance), and adjust metal through teeth of the rolling machine. In keeping the electrons even within the metal, you have to be mindful of rolling in one direction. Watch out for cracks, but don't confuse them with air bubbles.
