I am just getting started pouring. I have some questions about some things that I think are important. My first question is If i was to pour one 3 cavity molds of 3 inch grubs out of a do it mold, where about should i fill the pyrex cup to and how much coloring and glitter to put in? My second question is how long should I let the plastic sit in the mold before taking the plastics out of the mold? My 3rd question is when heating up my plastisol should i heat up the plastisol a little then put coloring and fully heat it or just stir the platisol and put coloring in and heat it up to around 350 degrees? My final question is how should I heat up the mixture.Like to get to 350 degrees do I heat for 1:00 then stir and heat again or in different time intervals? I am looking forward to starting this hobby and much need the help from the experienced guys on this site. Anything else you think is important feel free to send. Thanks!
