English: A concept one can now see in many old towns all over Turkey is: restore an old mansion, thus showing the building style of old, add showcases with objects on the history of town, and then, using mannequins and old utensils, show old local arts and crafts. I found the Kütahya one particularly fine. This man is making "biscuit":

The making of the objects to be painted, a material called bisküvi (biscuit. Wikipedia: "Biscuit (also known as bisque) refers to pottery that has been fired but not yet glazed. Biscuit is any pottery that has been fired in a kiln without a ceramic glaze. This can be a final product such as biscuit porcelain, or unglazed earthenware, often called terracotta, or, most commonly, an intermediary stage in a glazed final product. The porous nature of biscuit earthenware means that it readily absorbs water, while vitreous wares such as porcelain, bone china and most stoneware are non-porous even without glazing. The temperature of biscuit firing is today usually at least 1000°C, although higher temperatures are common. The firing of the ware that results in the biscuit article causes permanent chemical and physical changes to occur. These result in a much harder and more resilient article which can still be porous, and this can ease the application of glazes.

The first firing is called the biscuit firing (or "bisque firing"), and the second the glaze or glost firing. ")
