Masterclasses

This workshop is aimed at potters who have had some experience in glazing and wish to further develop their skills in both the application of glazes and their understanding of how glazes work. The workshop will seek to explain in clear terms the role of the individual materials and how they work to produce a glaze when combined with other glaze materials. Further it will explore how colours are attained and how certain faults can occur and be remedied.

The workshop will also examine the role of the three core components of a glaze:

- the fluxes (oxides)

- the glaze stiffener (alumina)

- the glass former (silica)

The workshop will involve a ‘hands on’ approach to the development of a number of glazes from a single base glaze through the application of Brongniart’s Formula. This workshop will examine glazes that develop in the Cone 9 -10 range (stoneware and porcelain temperatures of 1280 – 1300 degrees centigrade) and will attempt to cover areas such as:

- how is a glaze composed and how do the individual components interact with each other to cause a glaze to melt?

- how to obtain the specific gravity of a glaze

- what is Brongniart’s formula and how is it used

- safety in the use and application of glaze materials

- line blending a base glaze with a colorant (oxide or stain)

- line blending 2 glazes to produce a variety of glaze colours
