Q.
I have a hot pot that fires silver clay with pellet stove gel. Do I have to use PMC3 or can I use Art Clay? Is there a difference in the clay itself or does it just depend on the size/grams?

Hot pots are designed for use with low fire metal clay--PMC3® and Art Clay® 650 both fit the bill. The two brands of clay are different in a few ways:
