Underglaze Colours

Contem Underglaze Brush On colours are stain based underglaze brush on’s that hold their colour integrity over a wide range of temperatures from 1000ºC to 1250ºC. Without a top transparent glaze they give a matt surface which we would not consider food safe. As they do contain some glaze they do grab in to the pores of low biscuited clay or greenware but not high biscuited ware where the porosity has been reduced.

Please note that these images show the underglaze colours after a top glossy glaze has been applied and fired.
