The glass collection consists of one hundred and thirty objects. Although numerically not very large, it does contain several items that are exceptionally valuable because of the way in which the object is made or worked, or because of its period of origin. Most of them come from the workshops of Austria and Bohemia, with those from S.Reich & Co. of Vienna, J. Schreiber and Neffen of Karlsbad and Loetz Witwe of Klostermühl deserving especial attention. Murano and Croatian workshops are represented with just a few specimens.
According to number of objects, table glass is preponderant in the collection, particularly glasses and decanters. The oldest object in the collection is a blown glass bottle of the 15th or 16th century made in a workshop in Dubrovnik, once the property of the patrician Sarace family, as shown by an inscription.
As for objects that are important for their manner of workmanship and decoration, the following are particularly worthwhile: a vase of transparent, colourless glass of the 1880s (S. Reich and Co.) decorated with the demanding techniques of grinding and cutting, a goblet of ruby red glass of the second half of the 19th century (an unnamed Bohemian craftsman), ornamented with cutting, and a decanter of colourless clear glass of the 1880s (S. Reich and Co.), cut and engraved.
