I am really about to leap off into casting PR blanks, but I do have a question I'm hoping will save me some money.
How do I know--- or even guess--- at how much catalyst to add? I know it depends on the size of the mold and amount you are catalyzing.
My method will be to mix up two batches (say, one black and one white) for bi-color blanks. Add the colorants, mix well, add the catalyst, mix well.... pour the blanks.
If I am pouring the blanks into 3/4 X 2.5" or 4" PVC pipe molds, how much catalyst would I need to add?
If I were pouring the stuff into a square flat mold (like a sandwich tupperware container size) how much would I add?
Thanks for the suggestions!
