Recycling is a basic skill necessary to the jeweler’s studio. Working with materials like silver, gold, and copper makes it easy to melt and start over again or even create new alloys from your scrap metal. We will discuss the possible ways to recycle the scraps in the studio safely. Students will learn how to melt and pour ingots, use the rolling mill and draw plates to make fresh new sheet and wire for their studio needs, and the basics of alloying their metal. Recycling metal can be done with a variety of materials used as ingot molds including materials like graphite, cuttlebone, and charcoal as receptacles for the melted metal. These techniques have been used since ancient times as ingot molds for casting. So bring your scrap fine silver, sterling, copper, and gold, if you have it!

Melting metal and ingot casting tools
- Graphite molds and stirring rod from Amazon
- Torch that can metal small amounts of metal
- Borax: 20 mule team Borax can be purchased from the grocery store in the detergent aisle
Other potential ingot mold materials
- Cuttlebones. These can be purchased from bird suppliers and some jewelry suppliers. I get my medium to large bones from Great Companions online. Most cuttlebones are only able to be used once.
- Soft charcoal block. There are different kinds of charcoal blocks. Be sure to use soft charcoals solder blocks for casting. These can generally be used a few times if you are careful. The mold will deteriorate a bit with each use.
Metal and jewelry tools
- Rolling mill. A rolling mill is incredibly helpful to mill down the ingot into new sheet. This can be done with a hammer and anvil, but it's quite tough and takes some time, unless you have some blacksmithing skills.
- Draw plates. We will discuss these in class as well if you want to wait to purchase after the workshop. Do some research on the size, shape, and type of draw plate that you want. Usually, a good general size range for an all-purpose draw plate is going to be from about 3mm (around 9 gauge) to about 0.5mm (or 24 gauge.) One good draw plate can last more than a lifetime.
