OUMNH Number: 189  
Name and quarry location: Marmo di Candoglia, marmo del Duomo, from Candoglia, Novara, Piedmont, Italy  
Geological description: Coarse-grained calcite marble with grey tinted 'veins', and with small grains of quartz scattered through it, giving a slightly mottled appearance.  
Comments: This is the marble used for the Duomo of Milan, obtained from a quarry near the village of Candoglia, Mergozzo, Prov. di Novara, Italy (Jervis, 1889) . Watson wrote in 1916 that 'The marble has always been strictly reserved for the up-keep and necessary repairs of the Cathedral; it is therefore practically unknown in commerce.' ' is a light salmon coloured, coarsely crystalline rock, having a slightly mottled appearance when polished.' In fact the colour can vary from white (as in Corsi's specimen) to pale pink. The advent of diamond wire-saws has improved production sufficiently that some of this marble is now available on the commercial market to other users (Price, 2007).
