Gwendeanne Posted April 24, 2012 Report Share Posted April 24, 2012 I've never used any stains before. I'm getting ready to start experimenting. I've been pouring a tumbler cup mold with just plain white porcelain slip, into a plaster mold I made. If I add mason stain to the slip would it stain the plaster mold? If it does, would it effect or contaminate the next pouring w/o stain? I hope that makes sense. I just want to try and color my slip, but don't want it to ruin my plaster mold. Thanks, Gwen Link to comment Share on other sites More sharing options...

bciskepottery Posted April 24, 2012 Report Share Posted April 24, 2012 I've had mason stain -- mixed with a porcelain slip made from clay and applied as decoration on slabs -- leave color stains on plaster hump/slump molds. I know there are body stains -- that are added to white slip for coloring -- but have not used them in molds. Link to comment Share on other sites More sharing options...
icyone Posted April 26, 2012 Report Share Posted April 26, 2012 I think it would be best to try it on an old slip mold first. Whenever I use my red slip it stains the molds and almost everything else. So much that I use specific molds just for my redware slip. I see you're in Colorado. If you don't have an old or extra slip mold if you want send me a message with your email or address and I'll mail one out to you. I'm in Centennial.

Gwendeanne Posted April 29, 2012 Author Report Share Posted April 29, 2012 Thanks All. Icyone, I do have some old molds to experiment with...Thanks for offer and the heads up on the red stain. At the moment I don't have any red stain, but in the future I will be aware. Link to comment Share on other sites More sharing options...
