trace
CATEGORY: artifact
DEFINITION: Any physical characteristic of an artifact that can be described.
trace element
SYNONYMS OR RELATED TERMS: accessory element, guest element
CATEGORY: geology
DEFINITION: Elements present in a mineral in minor proportions (between 0.1-2.0%) but which are frequently characteristic of the original source of the material. Trace elements occur naturally in minerals in soils and sediment and are not added deliberately to a substance. Minute amounts of chemical elements found in minerals emit characteristic wavelengths of light when heated to incandescence. Quantitative analyses of metal, clay, obsidian, etc. can show the amounts of the trace elements present and may suggest a source. Source identification can lead to further interpretations of trade and economic systems.
trace element analysis
CATEGORY: technique
DEFINITION: The use of quantitative chemical techniques, such as neutron activation analysis or X-ray fluorescence spectrometry, for determining the elements present in a mineral in minor proportions. These methods are widely used in the identification of raw material sources for metal, clay, obsidian, etc. Trace elements emit characteristic wavelengths of light when heated to incandescence.
traceology
CATEGORY: technique
DEFINITION: The study of the traces left by use on the cutting edges of stone tools, with the aid of a microscope.
tracer
CATEGORY: artifact
DEFINITION: A tool for marking out or engraving designs, used to outline the raised areas on a surface. In metalworking, a tracer was frequently used to outline the raised areas on the surface of repoussé metalwork. A tracer is worked by hammering.
