In this process, granular refractory sand is coated with a mixture of bentonite clay, water and, in some cases, other additives (Fig. 1). The additives help to harden and hold the mold shape to withstand the pres-sures of the molten metal. The green sand mixture is compacted by hand or through mechanical force around a pattern to create a mold. The me-chanical force can be induced by slinging, jolting, squeezing or by impact/impulse.

A lab-created diamond, also known as a cultured diamond, is a clear gemstone that has been created by replicating the same conditions under which a diamond is made naturally.This involves putting pure carbon under enormous amounts of pressure and heat until it crystallizes.ab-created diamonds were first produced in 1954 by General Electric. Their method involved subjecting carbon to 400 tons of pressure. Scientists could at first only synthesize dust or very small stones, which were better suited for purposes such as tipping drill bits than for setting in jewelry.
