The crystal glaze is an enchanting acquaintance, it fascinates, smiles and steals the image with all its 'glossyness'. The formation of the crystals is a combination of the material & ingredients in the glaze and the temperature of the firing. Some of the ingredients are attracted to each other at particular temperatures, thereby increasing the crystals in the surface. I control the temperature changes in the firing and thus I shape the crystals. I can control the shape, size and color, but where and how many come - it is a interaction between the porcelain and the glaze.
Crystal glaze is a 'difficult friend' who is very sensitive to heat, thickness and certainly also weather conditions - there are always challenges with a Crystal glaze, which makes it extremely exciting to open an oven - every time even after more than 10 years.
