This is the first time I have ever tried this, to check for losses in the cupel.
I tried pulverizing the cupel to 100 mesh, and mixing it with 90g of legends fire assay flux with flour.
I let it sit in the furnace at 2000f for 40 minutes, then tried to pour with no success. It was a solid red hot mass in the crucible, and would not pour.
Not sure what went wrong?
Magnesia cupel btw.
