I teach a silver fabrication class and one of my students would like
to meltdown her scrap from pmc projects to fabricate with.
My response was these pieces would not be hard enough to withstand
regular wear as rings, She told me that she had on a pmc ring, and it
was very hard.
The ring was a band of approximately 14 gauge. I said that as a
soldered ring it was very strong because of it’s thick gauge, but if
I were to cut it, I could bend it very easily. thinner gauges would
not be as strong. she replied that the reason her pmc pieces are so
strong is she uses technical charts to “work harden” the pieces. And
don’t I know anything about work hardening?" So my question is this.
How does metal clay become as dense as fabricated metal…or even
cast metal when it doesn’t “vitrify?” Can heat do this?
I know that work hardening was the wrong term for her to use…I am
not familiar with any metal clays. all and any help is appreciated!
