Wine cups often had a tall foot which rested on dish-shaped stands. Baekja wares came from highly refined white clay, glazed with feldspar, and fired in regulated and clean large kilns. Despite the refining process, white glazes invariably vary as a result of the properties of the clay itself; firing methods were not uniform, temperatures ...
Methods for forming powders of ceramic raw materials into complex shapes are desirable in many areas of technology. For example, such methods are required for producing advanced, high-temperature structural parts such as heat engine components, recuperators and the like from powders of ceramic raw materials.
Clay identification is determined by a process of refiring the ceramic and assigning a color to it using Munsell Soil Color notation. By estimating both the clay and temper compositions and locating a region where both are known to occur, an assignment of the material source can be made.
Grog, temper for clay.

[1] Industrial applications are found in pottery, bricks, cement and some parts of the concrete and asphalt mixing processes. A ...
Clay beds which still produce ceramic clays are from primary and secondary deposits formed in the Late Paleocene and Early Miocene Epochs in formations that formed the Gulf Coastal Plain. According to all geological surveys the entire southeastern portion of the continent has abundant clay deposits, with the exception of all of south Florida ...
