Silversmithing

exploring design and creation with precious metals

Stanford University, ME298: Silversmithing and Design, 10 week class


Challenge

Design and create four small-scale pieces using precious metals

My Role

Designer, maker

 

Skills

  • Lost wax/investment casting

  • Sheet metal piercing

  • Brazing, soldering

  • Reductive wax carving

  • Metal sanding and finishing

 

Metal Piercing

The first piece I made was a piercing project. Metal piercing is a process of drilling holes into sheet metal, threading a thin saw blade through the hole, and cutting out a pattern.

I started with design sketching, ideating pieces that I could make from brass. From there, I drilled out holes and roughly cut out the pieces. After an initial sanding and cleanup, I soldered on two brass rings to use to attach to earring hooks. From there, I sanded and polished the metal to create the final piece - a set of brass mushroom earrings.

Investment Casting

The remaining three pieces were investment casting projects. We used the lost wax method, where a piece is first carved out of wax and then covered in plaster to create a mold. This is heated to melt the wax away, leaving a cavity in the shape of the wax piece in its place. Molten metal is then poured in, allowed to harden, then quenched to dissolve the plaster.

As with the first piece, I started with design sketches, then carved the wax, cast the metal, and sanded and finished.

 

design sketches - the challenge for this particular assignment was to create a piece with large volume but small mass

 
 

the wax carving took much longer than I expected. I took care to make it well since the better the mold is, the less finishing work I have to do on the final piece

 
 

The finished wax pieces are attached together to make a tree of parts. the shape and angles of each part are taken into account to maximize metal flow

After casting, each part is then cut off of the tree, and any leftover metal from the sprues and tree base can be reused in future casting projects
