Two hundred years in the future, in a fully colonized solar system, police detective Josephus Miller (Thomas Jane), who was born in the asteroid belt, is given the assignment to find a missing young woman; Julie Mao (Florence Faivre).
Perlite is made from a mined volcanic glass of the same name. As a raw material it contains water, trapped by the rapid cooling of lava. The moisture vaporizes explosively when heat is applied.
The composition of perlite resembles that of acid lavas, for example, liparite and dacite, which are chiefly composed of 65 to 75 percent SiO 2 and 10 to 15 percent Al 2 O 3 and which also include admixtures of Fe 2 O 3, CaO, MgO, SO 3, and R 2 O in proportions that range from fractions of a percent to single percentage units.
