In the Loupe

Welcome to “In the Loupe”! This summer at Plumb Gold we celebrated our 35th anniversary! Throughout the years, I have designed and made many pieces of jewelry. I am often asked, “How do you do it?” The techniques used for making jewelry are ancient and time honored.

Some pieces are fabricated out of metal sheet and wire. This means that each component is cut out, hand formed and soldered together to create a finished piece.

The majority of my jewelry, however, is cast. When designing a cast piece, the first step is to create a model in wax. Using saws and files, I sit down and hand-carve each design like a miniature sculpture.
I constantly turn the wax so I am sure the design is interesting from all angles. Once I am satisfied, the piece is mounted on a rubber base with wax wire

called a sprue. Then, the base is placed in a round metal flask. Very fine plaster investment is poured over the wax model and sprue. Once the plaster is set, the base is removed and the wax is trapped inside the plaster.

The entire flask is placed into a kiln and heated to over 1000 degrees! The wax melts out and what remains is a cavity within the plaster. The flask is then placed in a vacuum machine and molten gold is poured into the cavity. Once the metal cools, the plaster is removed. The casting is then polished and any stones are set. What started as wax is now a beautiful piece of jewelry!

Throughout this process, I always remember that, before jewelry was a business, it was an art. And at Plumb Gold it still is.
