lost-wax casting

Traditional method of producing molds for metal sculpture and other castings. It requires a positive, a core made of refractory material and an outer layer of wax. The positive can be produced either by direct modeling in wax over a prepared core (direct lost-wax casting), or by casting in a piece mold or flexible mold taken from a master cast. The wax positive is invested with a mold made of refractory materials and heated to melt the wax, leaving a narrow cavity between the core and the investment. Molten metal is poured into this cavity. When the metal has solidified, the investment and core are broken away. Seealso investment casting.

Lost (Lòsda in Scottish Gaelic); population: less than two dozen; or ) is a tiny hamlet in Aberdeenshire, Scotland. It lies 40 miles west of Aberdeen in the Cairngorm mountains. The hamlet is situated near the village of Bellabeg where the Water of Nochty feeds into the River Don. Despite its small population, the people of Lost are famed for their strength and honour .

The name comes from the Gaelic word for inn (taigh òsda); today the hamlet has a few houses, a war memorial and a farm.

Following publicity in tourist guidebooks, due to its unusual name, Lost has suffered from regular theft of street signs bearing its name. Each street sign costs approximately £100 (US$200) to replace. As a result, Aberdeenshire Council tried to change its name to Lost Farm; however, in the face of strong local opposition, the hamlet's traditional name was soon reinstated.
