Placuna Quadrangula
Placunidae, also known as windowpane oysters, windowpane shells, and Capiz shells, are a taxonomic family of saltwater clams, marine bivalve mollusks which are related to oysters and scallops. This family is best known for the shells of the species ''Placuna placenta'', which are translucent, and are commonly used in shellcraft production. In some cultures, they are cut into 2" x 2" and pressed by a 1/4" wood and are used as a form of light-admitting window. The windowpane oysters are valued for their translucent shell. The shells were originally used as a glass substitute in glazing, but nowadays they are mainly used in the manufacture of trays, lampshades and numerous decorative items. In coastal areas the flesh is eaten. Genera and species Genera and species within the family Placunidae include: * ''Placuna'' Lightfoot, 1786 ** ''Placuna ephippium'' (Philipsson, 1788) ** ''Placuna lincolnii'' (Gray, 1849) ** ''Placuna lobata'' G.

Placuna Placenta
The windowpane oyster (''Placuna placenta'') is a bivalve marine mollusk in the family of Placunidae. They are edible, but valued more for their shells (and the rather small pearls). The shells have been used for thousands of years as a glass substitute because of their durability and translucence. More recently, they have been used in the manufacture of decorative items such as chandeliers and lampshades; in this use, the shell is known as capiz shell (''kapis'')."Fisheries and aquaculture of window-pane shells" Malacological Society of London.

Shellcraft
Shellcraft, also known as shell craft, is the craft of making decorative objects, or of decorating surfaces, using seashells. The craft includes the design and creation of small items such as shell jewelry and figurines made from shells; middle-sized objects such as boxes and mirror frames covered in shells; sailor's valentines;Fondas, John. ''Sailors' Valentines'', Rizzoli International Publications, 2002 and larger constructions including mosaics and shell grottos. Shellcraft is sometimes simply a folk art which is carried out by amateurs, however, in some parts of the world, including the Philippines, it is a business.
