Ceramic raw materials: how to recognize them and locate the supply basins—mineralogy, petrography

2020

This tutorial paper is focused on the mineralogical-petrographic characterization of clayey raw materials with the purpose of sourcing supply basins and answering questions about the provenance of the corresponding archaeological ceramic artefacts. The first part gives general indications of how to profitably study archaeological ceramic thin sections through the polarizing microscope. Brief notes are provided on the theoretical basis of optical microscopy. A scheme is then provided for the petrographic description of ceramic samples, concerning the textural and compositional characteristics of aplastic inclusions and groundmass. Suggestions are also given for identifying any minero-petrogr…

The scientific instruments of the historical Mineralogical Museum of Palermo: testimonies of almost two centuries of mineralogical and petrographic s…

The scientific collections of the historic Museum of Mineralogy of Palermo are located on the second floor of via Archirafi 36 and are preserved by the Dipartimento di Scienze della Terra e del Mare (DiSTeM) of the University of Palermo. The historical edifice was designed by the architect Antonio Zanca and completed in the years 1933-1934. From the beginning, it has hosted the Institute of Physics at the ground and first floors, today entitled in honour of the famous physicians Emilio Segrè, and the Institute of Mineralogy at the second floor, which has kept one of the richest and ancient collections of Sicilian minerals. Today, the collections are partially exposed and are the subject of …
