Short about crystalline glazes


The surface of clay work is covered with glaze that is a mixture of various oxides. Under the influence of temperatures generated in a ceramic kiln, glaze gains permanent colors. One of the glaze type is a crystalline glaze, which, thanks to the proper combination of raw materials and firing cycle, can produce crystals that look like shimmering flowers. You can never know where the crystals appear, it is a random process that representing the uniqueness of objects made by this method. All glazes I create by myself from raw material like frit, zinc, silica ant many others. Crystals can grow in many different shapes, colors, structure, this can compared to form of ice structures saw on cold days. However, in ceramics world, the temperature needed to grow crystals is very very high … More about crystalline glazes You can find HERE

equire special treatment.

Some glazes do not like contact with acid and alkaline factors, which means that over time they may slightly change the color if they are in contact with e.g. citric acid in a long period of time or are cleaned in a dishwasher where we use very powerful cleaning agents.

This is due to the nature of the glaze I create. Obtaining a specific decorative effect is impossible without the use of enamel, which will be susceptible to the above-mentioned factors.


A series of good tips for using ceramics:

  • always wash dishes by hand using standard cleaning agents
  • do not soak ceramics in liquids that may be very acidic or very alkaline
  • do not wash in the dishwasher with very strong cleaners
