- Abstract
- A scientific classification of the finds discovered at Santa Cristina, a XIVth century site of Valdelsa devoted to the glass manufacture, and
the relative production cycle is proposed on the basis of a physico-chemical investigation, carried out especially by optical and SEM-EDS
microscopy, Mössbaüer and ICP spectroscopy, XRD diffractometry and TG-DTA thermogravimetry. It was verified that the glasses can be
divided according to their mean composition in two groups: one sodiccalcic in nature (three glass fragments and two glass masses) similar to
that found for the coeval Germagnana glasses, the other sodic-potassic in nature (four glass masses) with a significantly different composition.
Furthermore, a relevant number of vitreous samples, found inside a water tank at Poggio Imperiale (Poggibonsi-Siena) certainly filled in 1313,
has been completely characterized. These pale yellow-fumé glasses have a sodiccalcic composition. They have been obtained by melting
together ashes from coastal plants with non-particularly pure sand and have been decolorized by the intentional addition of manganese (IV)
dioxide. They do not reach the purity grade of the coeval Santa Cristina sodiccalcic glasses. A comparison of the obtained data with those
already published for the coevalMedieval Germagnana site or the Renaissance Gambassi site offers a satisfactory view of the glass production technology in Valdelsa and of its evolution from the XIVth to the XVIth century. (literal)
