The process for growing crystals in glazes dates back to the 7th century in the Tang Dynasty of China.  Research on the subject is not extensive, nor is the use of crystalline glazes in the world today.

     Specially formulated glazes fired in a rather unique style will promote this crystal development.  At some point in the firing process a nucleus of crystallizers is formed.  When this nucleus is held at the critical "growing temperature" for prolonged periods of time, it gets larger and larger.  You can see this resultant phenomena on these porcelain vessels.

     You will notice there are no two alike.......nor will there ever be!   They are impossible to duplicate.

     When you purchase a crystal glazed vessel you'll receive the piece, a registration card that lists the product info and serial number (left of vase below) and a 4x4 color pic of a macro view of one of the crystals, along with the easel to display it.  Enjoy!
