Product Information

Speedball’s Underglazes are unmatched in vibrancy and value. With a sensible sized amount of each colour, it offers a great opportunity to add underglaze colour for detailed brushing, sgraffito decoration or mono printing. These underglazes hold their true colour throughout the firing process. 

Size: 59ml (2oz)

Special features:

  • Rich colours when fired.
  • Can be applied to Greenware or Bisque
  • Can be used with or without clear glaze - Pictures depict true colours with and without a clear brush on glaze.
Firing Range

Formulated to fire in a range of 1021°C* (Cone 05) to 1243°C* (cone 6). These underglazes have also been successfully fired to 1305°C* (Cone 10).

Suitable to be used on greenware or bisque, each colour produces a soft, velvety finish which will intensify in richness when coated with a clear glaze.

*temperatures will vary with cone value because of the ramp/climb of the last 100°C.

OK

Found this a very thick lumpy underglaze, not very keen on it although it looked ok when fired.

Real issues with this glaze...

Unfortunately, this glaze has been really difficult to apply onto my bisque-ware. As it is quite thick (following vigerous shaking and stirring), I have had to dilute slightly with water. However the glaze and water do not mix at all well as the glaze forms tiny grains within the water. It becomes difficult to apply to the surface as it either is very watery or forms thick clumps of solid colour. I have had a similar experience with the burgundy too (although leaf green and white were ok). I'll be looking to try out alternatives like Spectrum and Amaco.
