kokopelle2012 Posted June 12, 2012 Report Share Posted June 12, 2012 I am working with Terracotta, making plant pots, and have a black iron oxide i've worked into a slip for creating black decoration on the unfired pots. i would like to do the same with white. My concern is that using a glaze essentially seals the clay, where what i'm hoping to do is color the clay without sealing it. Does anyone know of techniques or products for this? What i found that i thought might work was a white mason stain mixed with a light body clay slip? any advice is appreciated. -isaac Link to comment Share on other sites More sharing options...
clay lover Posted June 12, 2012 Report Share Posted June 12, 2012 How about a white stoneware slip? Link to comment Share on other sites More sharing options...

perkolator Posted June 13, 2012 Report Share Posted June 13, 2012 i'd say any white slip/engobe should work. here's a versatile, basic white slip recipe: 25 Kaolin/EPK 25 Ball/OM4 25 Custer Feldspar 25 Flint if you want it "whiter" you can sub for whiter clays, like grolleg; or even add an opacifier like zircopax or even tin.

I bought these things then realized I didn't ask, are they in ratio by weight or by volume? Link to comment Share on other sites More sharing options...
bciskepottery Posted June 22, 2012 Report Share Posted June 22, 2012 When the sum adds to 100, then it is usually by percent of weight. Link to comment Share on other sites More sharing options...
