TTTANTTE. A yellow or brown calcium silicotitanite, C aTi Si05, having a waxy luster, and often containing niobium (columbium), chromium, fluorine, and other elements. Titanite occurs in wedge-shaped monodime crystals, usually as an accessory mineral in granitic rocks and in calcium-rich metamorphic rocks. See also Sphene. 

Talc is a soft, large-molecule phyllosilicate mineral having a characteristic waxy luster. Ground to a floury texture, it used as bath powder and as a base for cosmetics. It is also used as a filler in food, as a dry lubricant, and in the manufacture of some kinds of paper.

Cotton is seed hairs that protect the seeds in their pods from desiccation in the dry season and from moisture in the rainy season. Under the microscope, cotton appears as a collapsed, tubelike fiber twisted at irregular intervals. In its natural state it repels water because of a waxy substance covering the fiber. Once the wax has been removed, cotton becomes the most absorbent fiber known to man. Cotton is cellulose it withstands moderate alkaline conditions but is easily affected by acids. Because of twist in the fiber, cotton lacks glossiness. Mercerization, a chemical process, gives luster to cotton fiber by straightening the twist.

The Group VA elements also show the distinct transition from nonmetal (nitrogen, N, and phosphorus, P) to metalloid (arsenic. As, and antimony, Sb) to metal (bismuth, Bi). Nitrogen occurs as a colorless, odorless, relatively umeactive gas with N2 molecules white phosphorus is a white, waxy solid with P4 molecules. Gray arsenic is a brittle solid with metallic luster antimony is a brittle solid with a silvery, metallic luster. Bismuth is a hard, lustrous metal with a pinkish tinge.
