Bogie1107 Posted January 26, 2018 Report Share Posted January 26, 2018 (edited) For a while now I've been trying to figure out how to add swirls to my colors when I'm pouring soft plastics. Does anyone have any tips? Edited January 26, 2018 by Bogie1107 Quote Link to comment Share on other sites More sharing options...
Jig Man Posted January 26, 2018 Report Share Posted January 26, 2018 For open pour molds I use a divided pyrex cup. I have read about using a double injector and alternating pulses but have yet to try it. Quote Link to comment Share on other sites More sharing options...
Frank Posted January 26, 2018 Report Share Posted January 26, 2018 If you have a Twinjector no need to pulse just have one color hotter than the other. The difference in viscosity will do the work for you. 1 Quote Link to comment Share on other sites More sharing options...
