The brick material culture of Urbino (UNESCO World Heritage, Central Italy) as inferred from a multidisciplinary archaeometric study on the historic architecture
Patrizia Santi, Francesco Veneri, Gianluigi Tonelli, Mario Tramontana, Laura Panzeri, Anna Galli & Alberto Renzulli
Roman to Modern times (19th century) brick samples from monuments, walls and other masonry buildings of the historic centre of Urbino were investigated through a multidisciplinary approach, including mineralogy and texture (thin section and XRPD), chemistry (major-trace elements), physical–mechanical properties and thermoluminescence (TL) dating, coupled with the historic literature data. TL mostly confirms the building periods of the architectural structures where the bricks were sampled, also emphasising for the Cathedral a building period that lasted more than three centuries. The absence of standardisation of the pyrotechnological processes probably led to the large variability of the physical–mechanical features even for bricks of the same building period. Uniaxial Compressive Strength of the investigated historic bricks, however, falls within the range of present-day full-bricks, and a general improvement of the brick quality from Roman to Modern times was highlighted, as well as a progressive refinement in preparation techniques before firing. The brick material culture of Urbino continues seamlessly, after the investigated periods, until the second half of the 20th century, testified by the presence of the brick factory of the Fornace Volponi, just outside the historic centre of the city.
