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 Glass-coated wire Glass-coating is a process invented in 1924 by G. F. Taylor and converted into production machine by Ulitovski for producing fine glass-coated metal filaments only a few micrometres in diameter. In this process, known as the "Taylor-wire" or "microwire process" or "Taylor-Ulitovski process", the metal to be produced in microwire form is held in a glass tube, typically a borosilicate composition, which is closed at one end. This end of the tube is then heated in order to soften the glass to a temperature at which the metal part is in liquid state and the glass can be
