Countertops are custom made and more scratch resistant as well as less porous than natural quartz surfaces, and don't need to be sealed like other stone surfaces. Due to the presence of the resins, quartz counters are less prone to staining. Thicknesses may be 6mm, 1.2 cm (1/2 inch), 2 cm (3/4 inch), 3 cm (1¼ inch) or 4 cm (1½ inch).
Quartz is, therefore, classified structurally as a framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. [10] Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation ...
The trade balance fluctuates widely because Kenya's main exports are primary commodities subject to the effects of both world prices and weather. In 2005 Kenya's income from exports was about US$3.2 billion. The payment for imports was about US$5.7B, yielding a trade deficit of about US$2.5B.

Fused quartz, fused silica or quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO 2) in amorphous (non- crystalline) form. This differs from all other commercial glasses, such as soda-lime glass, lead glass, or borosilicate glass, in which other ingredients are added which change the glasses' optical and physical ...
Cristobalite spherulites formed by devitrification from the obsidian matrix. Specimen from California, US; size: 5.9 cm × 3.8 cm × 3.8 cm (2.3 in × 1.5 in × 1.5 in). Cristobalite (/ krɪˈstoʊbəˌlaɪt /) is a mineral polymorph of silica that is formed at very high temperatures. It has the same chemical formula as quartz, SiO 2, but a ...
