The stoneware is burned in a gas kiln at a temperature between 1260-1300. Anna makes all the glazers herself using olive tree ashes for example. She uses also reduction fire with different combination of oxides in glazers, which can have as a base either chalk, felt spat or talc.

Anna also chooses to fire objects without glazer. Then she uses different techniques to mixing two or three varieties of clay to create or decorate.
