Archaeologists have sought to assess prehistoric pottery production by using hardness as an indicator of the relation between ceramic materials and firing temperature. Yet hardness testing commonly has been limited to a scratch test, which is imprecise and lacks the precision necessary to investigate these relations. Recent research has developed the application of indentation hardness testing for prehistoric ceramics. A sample of low-fired plainware pottery from the Shoofly Village Ruin in Arizona was used as a test case. Results indicate the technique produces continuous scale measurements which are precise and useful for the investigation of intraassemblage variations. The method overcomes many limitations of the traditional scratch test and may be used for either prehistoric or experimental ceramic samples. Indentation hardness testing provides the precision needed to more fully examine the complex relations between hardness and other ceramic attributes.
