Effect of Pigments on the Properties of Colored Slips for Porcelain Production

Abstract

The effect of introducing into slip ceramic pigments of different types on the change in the properties of the slip is studied. The pigments have a thinning effect on the slip and increase the build-up rate of the intermediate-product wall.Water suspensions of ceramic pigments can be neutral, weakly acidic or weakly alkaline and change the rheological properties of the slips which they color: red and light-blue pigments decrease while brown and rose pigments increase the thickening factor and viscosity.
