If you are using 4 or 6 cavity molds, a good practice is to get another identical set. Heat them up at the same time you start the pot; flux the melt and get both molds.
Fill one, and set it aside. Now, fill the second one and set it down.
Pick up the first set, open, dump, close and refill. Set it down.
Repeat with the second set.
It doesn't, and I wasn't implying that you use one.Where does the quoted text mention a mallet?
Is there such a thing as a "bad" pair?I just use a good pair of welders' gloves.
