Glass casting a 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 stacking 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 kiln to cool slowly. Glass casting Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the Egyptian period. Modern
Glass-coated wire and various alloy compositions. It has even proved possible to produce amorphous metal ("glassy metal") cores because the cooling rate achievable by this process can be of the order of 1,000,000 kelvins per second. Glass-coated wire receives all of its material properties from its microstructure. The microstructure in turn receives its properties from the rate at which the wire is cooled. The magnetic properties of glass-coated wires also differ greatly from the properties of amorphous wires and cold-drawn wires due to the difference of the internal stresses that are occurring in the wire. When choosing a metal for the wire
