Craquelure in the Mona Lisa, with a typical "Italian" pattern of small rectangular blocks Age craquelure in pottery. Craquelure (French: craquelure; Italian: crettatura) is a fine pattern of dense cracking formed on the surface of materials. It can be a result of drying, shock, aging, intentional patterning, or a combination of all four.
Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...

All ancient Greek and ancient Roman pottery is earthenware, as is the Hispano-Moresque ware of the late Middle Ages, which developed into tin-glazed pottery or faience traditions in several parts of Europe, mostly notably the painted maiolica of the Italian Renaissance, and Dutch Delftware.
Underglaze is a method of decorating pottery in which painted decoration is applied to the surface before it is covered with a transparent ceramic glaze and fired in a kiln. Because the glaze subsequently covers it, such decoration is completely durable, and it also allows the production of pottery with a surface that has a uniform sheen.
Fred H. Robertson and his father, Alexander, were important figures in the art pottery movement in America.

This part-glazing also occurs in other types of pottery, and for example is very common in the earthenware Chinese Tang dynasty tomb figures. Other pieces "reserve" areas in biscuit, by giving them a temporary coating of wax or something similar to keep the glaze off; this is a fairly common feature of Longquan celadon (which is porcelain in ...
Model of the STK settlement at Dresden-Nickern, showing longhouses and circular enclosures. The Stroke-ornamented ware (culture) or (German) Stichbandkeramik (abbr.

Gordon Childe, or Middle Danubian culture is the successor of the Linear Pottery culture, a major archaeological horizon of the European Neolithic in Central Europe.
