Hi everyone, I have continued to work with the new sterling silver metal clay trying to solve the problems I had from my last posting. Success!
Another problem I had with the first ring was the carbon indenting the metal during firing. This time I encased the ring with fiber blanket during the second firing.
First I fired the clay on the shelf (per the instructions) and then wrapped the ring inside fiber blanket with a small amount of fiber blanket inside the ring shank.
The ring came out fine fully sintered with no dents from the carbon!
