Coloured Slips And Underglaze?

Recommended Posts

Yes. I have done this. Bear in mind that adding these colors to a white slip will lighten them. Test first to make sure the colors are right and that the two formulas interact well before using on a good piece. Underglazes have ingredients in them that keep them wet and spreadable longer so this can cause issues.

if you have access to the actual mason stain used in the underglaze, you can make a colored slip.  just make your white slip in dry form and add 10% stain to this before mixing in water, then sieve well.

 

my go-to white slip recipe is equal parts (25% each) Silica, EPK, OM#4, and Custer Feldspar.  Very versatile white slip recipe that can be used from earthenware up to stoneware temps.

 

to make your own underglaze, use equal parts (33% each) Clay, Flux, and Colorant -- usually I'll do either EPK or Ball clay, Gerstley Borate or a frit like 3124/3134, then the colorant (oxides or mason stain).  usually i'll use CMC solution as the water for UG.
