So I've been reading and watching the videos about using low temp on powder coating so as not to soften the lead.
What is the situation regarding Hi-Tek? Am I losing hardness by repeated heating to 400 degrees for 8 to 12 minutes?
On the final heat I water dump them out of habit.
I typically use 3 coats and heat at 400 degrees for 10 minutes and then water drop them. I've never bothered to check the hardness because I've been fortunate enough to be able to use straight Linotype. Am I softening up my Linotype?
