Antique Victorian Mother of Pearl Cased Scent Bottles 19th C

Mother of pearl, is an organic-inorganic composite material produced by some molluscs as an inner shell layer; it is also what makes up the outer coating of pearls. It is strong, resilient, and iridescent. The outer layer of pearls and the inside layer of pearl oyster and freshwater pearl mussel shells are made of nacre. 

Both black and white nacre are and were used for design purposes. They were used as decorative motif used in cabinet making or silversmithing. The natural nacre may be artificially tinted to almost any colour. Nacre tesserae may be cut into shapes and laminated to a ceramic tile or marble base. The tesserae are hand-placed and closely sandwiched together, creating an irregular mosaic or pattern (such as a weave). The laminated material is typically about 2 mm thick. The tesserae are then lacquered and polished creating a durable and glossy surface.
