I spent the weekend putting together a system for annealing, and I wanted to see if anyone could help provide feedback on the results. Attached is a piece of brass with 750 tempilaq applied. I tried to set the annealing time based on when the brass first shows a faint glow. Ignore the condition of the brass as I've been testing with it several times and some of those instances pushed the brass well past 750 degrees.
This piece ran for 6 seconds starting at room temp. Is the heat progressing too low on the case? Anything else I should look for while I'm trying to get this process tuned?
