Hey,
I’m just about to start a medium sized run (for me) and I"m going to use charcoal and acid activated bleaching clay for the first time. When it’s in the boiling flask do people use the stir bar at the same time? Does the AC scratch in inside of the glass when it’s being stirred? Is it still ok when the run goes near dry? Will it wreck equipment? Is there a standard method for this?
