Porcelainclay

My work consist of handmade  objects in porcelain clay: it is a fine grained and pure clay and quit suitable as the underground of crystal glazes.

During the heating process in the kiln the form shrinks till 80% of the original size.

Crystal Glazes

A crystal glaze on a porcelain clay creates a power of attraction, but it demands a lot of attention, because a crystal glaze has a changeable character.

I develop my own glazes.

The first heating is till ca. 1000 degrees (biscuit).

Then I some layers of glaze over the biscuit form.

The next heating is about 1260 - 1285 degrees, it depends on the characteristic and the melting point of the glaze.

When the melting point has been reached, the kiln must be cooled till ca. 1100 - 1000 degrees.

During this cooling process small crystals will be formed.

The character, the form and the size of the crystals depends on the structure of the glaze and the heating process.
