Isak Isaksson has been experimenting with crystalline glazes since the mid 1980s. His galaxy-like glazes are constantly evolving and moving boundaries for what is considered possible to achieve during ceramic firing. With a chemist’s precision and an enormous stubbornness and curiosity, Isaksson can spend years developing a specific glaze with a unique expression. The base of the glaze is a so-called frit, or glass mass, which Isaksson mixes himself or buys ready-made in powder form. Frits are prepared by melting specific elements and adding water, then drying and grinding to a fine powder. The coloring of the glaze comes from the substances mixed into the frit. There are infinite expressions within the world of crystalline glazes. Below some examples. More about the process of creating a crystalline glaze here.
