Aplastic - Non-plastic inclusions in clay. May be natural or added (temper)
Base - The bottom portion of a vessel, that comes in contact with the surface it rests on during normal use. These are usually rounded or pointed but flat and ring bases are also seen.
Body Fabric- The mixture of clay and inclusions (temper) used to form vessels.
Clay - Fine grained sediment, with a particle size of less than .002mm which is malleable and plastic when wet, and which forms a ceramic when fired.
Coil Construction -- A manufacturing technique involving the forming and joining of
narrow coils of clay to create the walls of a vessel.
Cord Impressed - Decoration on pottery made by directly pressing cord against the wet paste in patterns. This is a "decoration." Not common in South Carolina.
Cord-Marked - Cord impressions left when a cord wrapped paddle was used to malleate the coils. This is a "surface treatment."
Earthenware - Low fired, porous pottery.
Fabric-Impressed - Woven textiles applied like cord marking. A surface treatment. Both bunched fabric with soft cordage for the weft and warp, and fabric with a rigid warp were used. see also Net Impressed and Textile Impressed.
Fire cloud - An area of a vessel that is darker due to a reduced firing atmosphere in a small area. May be caused by contact with another vessel, for instance.
Incised - A stylus is used to scratch lines into the body. Can be applied to wet or dry clay. A decoration.
Inclusions - See aplastics.
Kaolin - See Rice. Kaolin is a white clay used in porcelain manufacture. Matures at a high temperature.
Lip - The top edge of the vessel mouth. Part of the rim.
Lug Handle - Flat semi-circular protrusion added for lifting.
Neck - The section of a vessel between the body and the rim on vessels with constriction.
Net-Impressed - Like fabric impressed, but the textile is knotted together rather than weaved
Node - appliqued pellet
Notched - Single lines on the rim or collar of the vessel.
Oxidation - When fired in an oxygen-rich firing atmosphere earthenwares turn a uniform
Paste - Like body fabric, the mixture of clay and inclusions used to form a vessel.
Punctate - Various objects are used to poke small indentations into the body.
Reduction Atmosphere - Oxygen-poor firing atmosphere that results in the retention of
organic material and a darker color than oxidizing atmospheres.
Rim - The upper portion of the vessel, including the lip.
Sherd - A fragment of a broken vessel.
Shoulder The upper part of the body of a restricted rim vessel, or the portion between the
maximum diameter and the rim.
Temper - An agent purposely added to the paste in order to strengthen the clay, and
improve its workability.
Type - Pottery that shares attributes on a non-random basis. Sometimes used
interchangeably with ware or series, but often refers to specific decorative motifs or
treatments within a series or ware group.
Ware Group - A cluster of pottery types that share similar methods of manufacture, body
fabric and vessel form.
