“Marmi mischi” (mixed marbles) are artificial Ca-rich glass decorations used in Sicily during Baroque, to adorn wall and altar. They are known as “vetri di carcara” and were obtained by burning in specific furnaces (carcara) of limestones, marly limestones or dolomitic limestones, to obtain CaO. After roasting of the carbonatic rocks, the glassy to vitreous materials found at the bottom of the ancient limekilns as a secondary product of the lime production, mostly green-blue coloured, was collected and used as “mischi” glass decorations (Montana and Gagliardo Briuccia, 1998). Similar Ca-rich glassy materials from the “Fiore Deposit” have been already studied by Triscari et al. (2009) to carry out informations about colour origin. Another study by Artioli et al.

Abstract
“Marmi mischi” (mixed marbles) are artificial Ca-rich glass decorations used in Sicily during Baroque, to adorn wall and altar. They are known as “vetri di carcara” and were obtained by burning in specific furnaces (carcara) of limestones, marly limestones or dolomitic limestones, to obtain CaO. After roasting of the carbonatic rocks, the glassy to vitreous materials found at the bottom of the ancient limekilns as a secondary product of the lime production, mostly green-blue coloured, was collected and used as “mischi” glass decorations (Montana and Gagliardo Briuccia, 1998). Similar Ca-rich glassy materials from the “Fiore Deposit” have been already studied by Triscari et al. (2009) to carry out informations about colour origin. Another study by Artioli et al. (2009) characterized similar Baroque glass decorations from Palermo Churches and defined them as carcara glasses. In this study we provide information on the used raw materials and pigments used for glassy decorations of an altar frontal (Pallium altaris) from the Messina Regional Museum. To reach this objective, glass decorations have been analysed by means of portable X-Ray Fluorescence through in situ not destructive analyses.Pubblicazioni consigliate
