Way back when I used LC plastisol - I really like it - but it hard packed after a few days if not stirred. So keep that in mind you may have to mix it a lot if it is the same as it was years ago.
This is what I use,
Cin. Red No salt
8oz. plastisol,,,,,3 drops Root Beer,,,,,,,8 drops Plum,,,,,, 1 drop White - LC colors
Cin. Brown with salt
8oz. plastisol,,,,8 drops chocolate,,,,6 drops black - LC colors
This oil leaching is a problem. The Calhouns never did that. Other brands do. Back when I was selling to stores I had frogs in clam shells. When I went back to check inventory a month later all the frogs had slid to the bottom of the clams and were all wadded up. There also was oil in the bottom of the clams. I am not sure,but I think that was Do-it plastisol. When Poly-Sol 1st came out and sent samples to a lot of us. I told them I would not use it because of oil leaching a few days after they were demolded. I think they reworked the recipe to solve it - not sure ? Are they now BP ?
