Milky glazing as a way of hot vessel surface treatment

Milky glazing is one of the ways to make the surface of ceramic vessel moisture-proof. This technique became so widely spread in modern pottery making for its simplicity and availability. The process itself consists of dipping the already fired ceramics into the milk or dairy produce and refiring it again in the roaster. An important result of this milky glazing process is connected with a special decorative color of the pottery surface. The hallmark of the milky glazing on ceramics is the existence of a dark-brown thin coating, which evenly covers the inner and the outer surfaces of the vessel. At the same time when the milk was just boiled in the pot this thin coating appears only on the inner surface. Such kind of a pottery technique could have been developed most probably in a society of cattle- or sheep and goats breeders, who had a surplus of dairy produce.
