When pouring plastic, I heat up 2 full cups 99% of the time, I do have 2 pots that will hold 2 quarts and have used them a few times, they are for big orders of swim baits, I heat them to 350 degrees then back it down a little, and stir more, then start pouring SLOWLY as not to spill any, have had SEVER 3rd degree burns on legs and both feet, spent 1 week in the hospital, had to had skin grafts done, that was the first/and last time I hope I ever spill any plastic, been HAND pour lures now for almost 13yrs, and only 1 problem in the first 10 yrs.
