Lost wax casting - Ring making

Joining a class at Bushwick Jewelry Casting, I was able to spend time learning how to do lost wax carving and casting, as well as hand finishing and polishing to create several .925 Sterling Silver rings.

Behind the scenes

  • Rough carving

    To begin each piece, I started with roughly hand carving the base shape of each ring. Using hand and drill files, I carved out the gestures of each ring into purple hard wax.

  • Refining the form

    Using soft buildable wax, smaller files, sand paper and fine carving tools, I began to refine the forms of each of the rings. As I was creating rings for family members and friends, each style was distinct and took time to hand finish.

  • Sprueing and creating a tree

    Over the course of the three weeks I created eight different rings to cast. In order to invest the metal, I had to build a tree connecting all of the rings, this allows for proper flow of the metal during casting.

  • Investing

    Once the tree was formed it was placed into the investment tube, we then filled this with a water soluble casting medium to serve as our mold. This was then place in a kiln to slowly fire away the wax, leaving only the negative behind.

  • Selecting material

    As a part of this process I was able to select the material I wanted for the rings. In this case I selected .925 Sterling Silver casting grain.

  • Investing

    Because I was actively torching hot metal, I didn’t photograph the investing process, but it did require some serious eye protection and torching a crucible until there was molten metal!

  • Finishing and polishing

    When the rings are invested and then quenched, they come out looking very dull and pale. From here I removed the sprues from each ring and began to file away at unnecessary parts.

  • Final polish

    After a lot of buffing and polishing, the rings begin to take final form with a soft glossy shine.

The final products

Several of the rings from this collection are still in the works, or were hastily gifted to friends and family before I could capture them in their full glory. Here’s a collection of the final images.
