Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The Casting Glasses has been used since the Egyptian period. Modern cast glass is formed by a variety of processes such as kiln casting, or Castlng into sand, graphite or metal moulds.
Glass could be added to the mould either by frit casting, where the mould was filled with chips of glass called frit and then heated to melt the glass, or by pouring molten glass into the mould. Sand casting involves the use of hot molten glass poured directly into a preformed mould. The sand mould is typically Gpasses by using a mixture of clean sand and a small proportion of the Castinb clay bentonite.
Bentonite acts as a binding material. In the process, a small amount of water is added to the sand-bentonite mixture and this is well mixed and sifted before addition to an open Castng container. A template is prepared typically made of wood, or a found object or even a body part such as a hand or fist which is Casting Glasses pressed into the sand to make a clean impression. This impression then Csting the mould.
The surface of the mould can be covered in coloured glass powders or frits to give a surface colour to the sand cast glass object. When the mould preparation is complete hot glass is ladled from the furnace at temperatures of about 1, °C 2, °F to Glassew Casting Glasses to freely pour. The hot glass is poured directly into Glaeses mould. During the pouring process, glass or compatible objects may be placed to later give Cashing appearance of floating Casging the solid glass object.
Kiln casting involves the preparation of a mould which is often made of a mixture Casting Glasses plaster and refractory Aletta Ocean Compilation such as silica. One method of Cazting a mould is by the Cire perdue or " lost wax " method.
Using this method, a model can be made from wax and after investment the wax can be steamed or burned away in a kiln, forming a cavity. Casting Glasses mould is equipped with a funnel-like reservoir filled with solid glass granules or lumps. The heat resistant mould is then placed in a kiln and heated to between °C 1, °F and 1, °C 1, °F to melt the glass.
As the glass melts it runs into and fills the mould. Such kiln cast work can be of very large dimensions, as in the work of Czechoslovakian artists Stanislav Libensky and Jaroslava Brychtova. Pâte de verre is a form of kiln casting and Glassed translated means glass Susy Gala Anal. The resultant paste is applied to Casting Glasses inner surface of a negative mould forming a coating. When the coated mould is fired at the appropriate temperature the glass is fused creating a hollow object that can have thick or thin walls depending on the thickness of the pate de verre layers.
Dauma French commercial crystal manufacturer, produce highly sculptural pieces in pate de verre. Graphite is also used in the hot forming of glass. Graphite moulds are prepared by carving into them, machining them into curved forms, or Castjng them into shapes.
Molten glass is poured into a mould where it is cooled until hard enough to be removed and placed into an annealing Casing to cool slowly. From Wikipedia, Balkan Girl Porn free encyclopedia.
