Beautiful Crystalline Pottery


Crystalline glazing was first explored in the early 1900’s. It was not fully used as an art form until the 1970’s, with the development of electric kilns. The glazing process is a very elaborate one requiring a delicate balance between, clay bodies, glaze materials, and firing schedules with precise temperature controls. Zinc oxide and other elements provide the “seed” for crystal growth. After reaching the desired high temperature, the kiln temperature is dropped to between 1900 and 2100 degrees for a preselected time period, usually 60 to 240 minutes. It is during this time that the zinc seed has time to develop into crystals. The length of the soaking time will determine the ultimate size of the crystal.
