In our studio in the Netherlands the work of my wife, Ines de Booij, concentrates on slipcast design vases. In spaaying glazes we apply a similar approach in controlling the thickness of the glaze layer as in dipping glazes. The glazes are prepared in a fixed thickness, similar to lowfat yoghurt. When we spray the glazes we let the spray surface just become shiny from the wet surface. This way the glazemix reacts to the level of absorption of the bisque ware. Beware of not changing the bisque firing temperature; the thickness of the glaze batches may differ with different glazes. I hope I am clear with my explanation.
