Compositional analysis of local redwares: characterizing the pottery productions of 16 workshops located in Southern Québec dating from late 17th to late 19th-century

Over 300 colonial coarse earthenwares kiln wasters uncovered from 16 potter's workshops in southern Québec were analysed using inductively coupled-plasma atomic emission spectrometry (ICP-AES). A sub-sample was analysed through inductively coupled-plasma mass spectrometry (ICP-MS). These analyses were first conducted for the needs of defining ceramic reference groups, but the study also demonstrates that major elements and ICP-AES geochemical datasets can be particularly instructive for the sourcing of ceramics made out of glacial clays.
