Pottery is one of the most common and durable artifacts on archaeological sites throughout the world.

Pottery-making differs across time and space, reflecting variation and changes to technology, function, and style. These qualities make it especially useful as a tool to understand the lives of people in the past. Pottery not only provides a basis for dating but also helps archaeologists study diet, cuisine, technological change, social learning, social boundaries, kinship, trade and exchange, migration, demography, and many other topics. As such, the analysis of pottery forms a cornerstone of many archaeological research programs.

Researchers in the Ceramic Technology Lab (CTL) conduct analyses on pottery and clay using a variety of techniques. The lab is equipped for basic paste characterization studies, including a binocular microscope for gross identification of inclusion or paste constituents, a petrographic microscope for precise mineral identification in thin section, and an electric furnace used for re-firing experiments and the preparation of clay samples. Further analyses, including elemental analysis, are conducted in collaboration with other research laboratories at the University of Florida and elsewhere.

The CTL maintains three important collections:

Pottery type collection

Pre-Columbian and historic period aboriginal pottery from Florida and the southeastern U.S. View examples of these in our Image Galleries.

Comparative clay sample collection

Clay samples from throughout Florida and neighboring areas collected to document geographic variability in clay mineralogy and chemistry.

Thin section library

Comparative “library” of pottery and clay sample thin sections, generated primarily from characterization studies conducted at the CTL.
