Quote:Yes im going to make a thick master copy during the week. I use industrial strength casting plaster.i\'m not sure what insustrial strength casting plaster is, but definalty make a master copy and a copy mold using either ultracal30, hydrocal white, or #1 pottery... I used ultracal30 and acryl60 plaster hardener, and I think I could make about 17,000 pulls before the mold started to loose detail.
