Jewelry Design, Week 1
I've been working on a project, and came to a plateau in my design process. I just recently enrolled in a jewelry design class to help me solve some of those problems. Anyway, in the first week, we learned about the properties of gold, and made an ingot. The first day was like a high school chemistry class: measuring metal components on a scale, lighting up a Bunsen-Burner-like-torch, learning what alloys are about. Depending on the properties of metals, some are softer, and some are more brittle, but one thing the professors reiterated was to be mindful of purity (we use a charcoal brick to hold the molten metal while it cools). Some jewelry designs require the brittle properties of copper, while some designs prioritize color, which also affect alloys. Some metal properties facilitate conductivity better than others. It's all terribly fascinating.
Here is the ingot I made.
The flux used is Borax, but it looks like silicone at high temperatures, and glass after it cools.
