Bring a large pot of water to just to a boil. You want enough water to comfortably hold all the shrimp. There should be about 1 to 2 inches (2.5 to 5.1 cm) more water than there is shrimp.
The amount depends on the type of mineral. A large group of minerals  the opaque minerals  do not transmit significant light, even in thin section. These minerals do, however , reflect light back that can tell us a great deal about their identity and origin. These minerals typically have significant metallic bonding (e.g., native elements, sulfides, oxides).
Besides viscosity, there are other factors that influence the ability of a polymer to crystallize. One of them is the nature of the side groups on the polymer chains. With very bulky side groups, or side groups that vary in an irregular way, the chains have a hard time organizing into an ordered, crystalline solid.
