What I want to accomplish

  • Make some glass slugs for testing polishing processes

What I've done

I bought another muffin pan and pre-fired it. This destroyed it. I think the oxide layers that formed were thicker than the metal in the pan. It had the consistency of a Sao biscuit.

I ordered a set of four stainless steel drinking cups from ebay. I pre-fired them. There was lots of black gunk on the outside afterwards, but I scrubbed it off with a wire brush, and then scoured with sand. They were still black, but without loose contaminants. They kept their strength.

I applied a single layer of batwash and dried them on a hotplate. I measured out 130g of crushed glass into each of the four cups and ran them through the same profile as last time:

Pending.
