bigbasser Posted February 24, 2005 Report Share Posted February 24, 2005 Does any body notice that when you warm up your plastic it increases? Such as I pour half a cup in, then warm up and have somewhere between a half and three quarters of a cup after expanding. Also are all your guys recipes for a half cup of "cold"(uncooked) plastic? Thanks Quote Link to comment Share on other sites More sharing options...
Fleury9816 Posted February 24, 2005 Report Share Posted February 24, 2005 I have noticed the plastic expanding myself. I usually do 4 oz. at a time and it seems after heating that I have a little over the line. Quote Link to comment Share on other sites More sharing options...

GB GONE Posted February 24, 2005 Report Share Posted February 24, 2005 I feel pretty sure that the recipes everyone have posted are for "uncooked" plastic..I know all the ones I have personally tried have worked great by following them in the posted amounts..before heating. The plastic does expand but, as Nova pointed out, it will contract when it cools in your mold. jim Quote Link to comment Share on other sites More sharing options...
