Much of the wax used in investment casting can be reclaimed and reused. [2] Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process. Investment casting is so named because the process invests (surrounds) the pattern with refractory material to make a mould, and a molten substance is cast into the ...
Lost-wax casting – also called investment casting, precision casting, or cire perdue (French: [siʁ pɛʁdy]; borrowed from French) [1] – is the process by which a duplicate sculpture (often a metal, such as silver, gold, brass, or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.

The second principle is known as Resource Investment. [3] This principle of COR states that people will tend to invest resources in order to protect against resource loss, to recover from losses, and to gain resources. [3] Within the context of coping, people will invest resources to prevent future resource losses.
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
Ceramic mold casting, also known ambiguously as ceramic molding, [1] is a group of metal casting processes that use ceramics as the mold material. It is a combination of plaster mold casting and investment casting. [2] [3] There are two types of ceramic mold casting: the Shaw process and the Unicast process. [4]
The Kuznets swing (or Kuznets cycle) is a claimed medium-range economic wave with a period of 15–25 years identified in 1930 by Simon Kuznets. [1] Kuznets connected these waves with demographic processes, in particular with immigrant inflows/outflows and the changes in construction intensity that they caused, that is why he denoted them as "demographic" or "building" cycles/swings.
