Abstract

AN EXPERIMENTAL STUDY TOWARDS THE APPLICABILITY OF CERAMIC MATERIALS AND SURFACES AS ALTERNATIVE DRAWING MEDIUM. The use of specific colour and tonal range when drawing on paper is a luxury that does not exist when drawing is executed on ceramic ware. Most colour pigments and tonal ranges are often only revealed after glaze firing, this makes the visualization of the final product very difficult. In an article 'Glaze Page', De Boos writes: "One of the first lessons we all learn when glaze testing is that the most reliable characteristic of glazes is their unreliability. " By means of thorough pre-testing and careful documentation a range of pastels and pencils have been developed resulting in minimal variation after glaze firing, if kiln temperature and glaze specification are kept constant. The use of commercially produced ceramic colourants which for the most part are similar to the final product, aids visualization of final result after glaze firing. Although the results were sometimes unpredictable the candidate has succeeded in identifying specific problem areas and thus limiting variation to a minimum. The possibility of making drawing on ceramic ware a permanent part of everyday living has thus been achieved
