I think the fumes from melting 550 lbs clouded my judgement.
No, just kidding. I want to have enough plasticine on hand to create large scale characters. When you only have 100 lbs of one color, that means there is generally enough to create one head and shoulders and part of another character. I want to be able to have group shots.
I additionally want to have a stockpile that will age to allow the clay to be better conditioned. When I add wax to the clay, it’s not usually until the next year that it is spot on. Surprisingly, this stuff gets better with age.
