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).
For one thing, all wavelengths of light -- including visible light -- affect laminating films, print media top coatings and printed images to some degree. Of course, there is nothing we can do about the effects of visible light. And optical clarity is clearly a desirable characteristic of an overlaminate film.
