All china cabinets have glass fronts. The idea of china cabinets was originally the result of a growing popularity in 17th century Europe with the accumulation of porcelain ceramics from the Orient. The cabinet was a means of displaying your collection of porcelain dinnerware as well as heirlooms and other items of interest. Hence, it made sense that the front be glass. The cabinet’s sides and shelves may be glass too so as to add that extra visibility.
Today, a china cabinet is not only a place to keep your chinaware but silverware, glassware and general dinnerware. Items you would find in the cabinet include bowls, plates, cups and glasses. China cabinets would often have wooden drawers and/or a set of shelves whose contents are hidden from view by an opaque door.
