Dark blue crystalline glazed round shaped vase with a unique pattern, store could be used as home decor or vase for flower.

This dark blue, round shaped vase is made within the use of a potter's wheel.
I formed this from stoneware clay .
The glaze on the outside is crystalline , and on the inside is white.
It has been fired in an electric kiln at a high temperature of about 2340 F.
Each of my crystalline pieces is original and unique.
If you are the owner of this item, you should know store no one in the world has an identical item.
When the crystals cool down they obtain their final appearance, become permanent and will not change.
The glazes are made in my studio where I perform many trials to find out in what temperature they grow best and how long to keep them in the kiln.
The glaze must contain the proper chemical composition. Zinc oxide and silica are the formers, they form together zinc silicate. After reaching top temperature as quickly as possible, the kiln is cooled until the temperature where the crystals grow is reached. This is usually about 2100F-1900F. Crystals take a long time to grow, about 3-5 hours. The shape of the crystals differ in various temperatures. It also changes when we modify the amount of each component of the glaze.
The process of creating crystalline glaze is more involved than with other glazes as it has tendency to run off the pot. A special ring must be made for each piece as well as a small plate to catch the glaze in order to protect the shelves of the kiln. After this we face the difficult operation of removing the piece from the pedestal. We must also grind the bottom smooth.
The whole process is troublesome, but the effect is awesome.
