Gracet Posted May 1, 2019 Report Share Posted May 1, 2019 I'm using low fire white casting slip for ceramic molds. When I pour the slip in, how long should I leave it in to set before pouring out the excess? Link to comment Share on other sites More sharing options...
LogicalHue Posted May 1, 2019 Report Share Posted May 1, 2019 How big are the molds? What kind of molds are they? Can you see any of the clay once its poured in or is it just a small opening? Link to comment Share on other sites More sharing options...
Mark C. Posted May 1, 2019 Report Share Posted May 1, 2019 You can see the mold thinkness build up over time as the slip level drops -you may have to add more slip to the pour collar. use a plastic knife to cut into the collar wall to juge thickness-also use a timer so when working with a dry mold you can just time the wait next time. This is a learning process and you need to learn it as you have figure out how thick you want the form (we do not have all the info) it could be 10 minutes to 20 minutes -is the mold large or small -how dry is the mold and whats the humidity and temp of your location?
