♦ THE ART OF BACCARAT CRYSTAL IN 7 WORDS :
Colour : From the 19th century onwards, the Baccarat range was expressed in multitude of colours, produced by adding metal oxides to clear crystal : blue with cobalt oxide, violet with manganese oxide, green blue with copper oxide, yellow with uranium oxide, black with manganese and oxides of copper and chromium.
Gilding : Used since 1833 by Baccarat, gilding, a paste made of 24-carat gold, is applied with a brush. The piece is then annealed at a temperature of 460°C to set, and the gilding is itself polished with an agate stone to give a shiny gold aspect-this is the « burnishing ».
Enamelling : Discovered in antiquity, enamelling is a technique that has been used by Baccarat since 1840, notably in the decoration of armorial glasses. A tinted metal oxide paste is applied with a brush before being fired at a temperature of at least 600°C.
Engraving : A decorative technique applied to cold glass consisting in removing material in different ways : using an acid bath where the decoration drawn in negative is eroded by the action of the chemicals ; at the wheel, as was already practised in ancient times, by removing the material with the aid of small « burrs » ; sandblasting, that is to say the pressurised projection of sand on the object in order to buff off the desired areas.
Melting : At a temperature of about 1400°C, silica (very fine and very puresand), sodium and lead oxide bake in a Baccarat oven for at least one day.
Blowing : Dipping a blowpipe, a hollow metal bar, into in the furnace, the glass master gathers a bubble of molten crystal called a « parison ». Then, blowing into the pipe, he gives the object its hollow form.
Cutting : Using a grinding wheel on cold glass, the craftsman applies a decorative pattern : bevelled, flat cut, diamond-shaped, pontil, rich cut and so on.
