I use HTP's, zincs and LX's (depending on the container obviously ) with this wax, and have never used more than 6% (1oz.) per pound, I'm with Trish, if I have to use more, than I just don't use that FO anymore, not cost efficient. I haven't noticed any difference in whether I heat my jars or not. Michael, sorry you could never get this wax to throw for YOU, I think I've had only ONE FO so far not throw for me with this wax.
