The sand was made by mixing heated sand with melted wax. The wax would repel water when the sand was exposed to water. [2] Magic sand was originally developed to trap ocean oil spills near the shore. This was done by sprinkling magic sand on floating petroleum, which would then mix with the oil and make it heavy enough to sink.
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand—known as casting sand—as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. In 2003, over 60% of all metal ...
Produce wax patterns: Although called wax patterns, pattern materials may also include plastic and frozen mercury. [6] Wax patterns can be produced in one of two ways. In one process, the wax is poured into the mould and swished around until an even coating, usually about 3 mm (0.12 in) thick, covers the inner surface of the mould.
Illustration of stepwise bronze casting by the lost-wax method. 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.
The unaffected sand particle does not have this coating meaning that water can infiltrate through the sandy soil. Other important soil water averting factors have been found to include soil texture, microbiology, soil surface roughness, soil organic matter content, soil chemical composition, acidity, soil water content, soil type, mineralogy of ...
Wax patterns are used in an alternative casting process called investment casting. A combination of paraffin wax, bees wax and carnauba wax is used for this purpose. In this case the wax "pattern" is melted out from the mould cavity which is normally a rigid plaster like material rather than sand, so the wax "pattern" can only be used once. [5]

His process utilized no glue and pressure from the other sand grains alone held the artwork together. When Clemens completed a sand bottle he sealed the bottle with a stopper and wax. [2] At first, Clemens' work was simple and geometric in nature, diamond shaped patterns against an ivory white background was a regular motif in his earliest work ...
