(French "lost wax") A casting technique in which a model is first made of wax, which is then enclosed in a clay and plaster mould The wax is melted out through a vent, and molten metal - usually bronze - is run in to replace it To cast a hollow object it is necessary to insert a core of burnt clay, so that the wax occupies the thin surrounding space between this and the mould
The French for Lost Wax This is a process in which a model is carved in wax then has a mold built up around it When this is heated, the wax melts and runs out through small holes in the base of the mold, which is thus left with the exact contours of the original wax model The mold can then be filled with molten glass or bronze which, on cooling, appears as an exact replica of its original model Some molds are re-usable, others are destroyed when opened René Lalique used this technique for his early glass and Frederick Carder used it from 1933 GANTAD
> "Lost wax," a technique for making sculpture in which a model is carved in wax, encased in a plaster mold and heated so that the wax melts and runs out The mold is then filled with molten casting bronze When cool, the mold is broken to release the sculpture Often used by sculptors working in bronze, this technique was sometimes used by René Lalique for glass casting Lalique cire perdue pieces are unique
(French for lost-wax casting) A casting process for which a sculptor must first produce his sculpture in wax He creates a mould around this made of refractory materials When the mould is heated, the wax melts away, so that molten metal can replace it, reproducing exactly the original wax sculpture
