Calcium fluoride is a mineral composed of calcium fluoride (CaF2), the principal fluorine-bearing mineral. It occurs as cubic, isometric crystals and cleavable masses. When pure, it is colorless and transparent, or translucent with a glassy luster. Impurities cause color in the stone, and several varieties exhibit fluorescence. Usually found either in pure veins or associated with lead, silver, or zinc ores, it is common in limestone and dolomites. Fluorite comes in a wide range of colors and has subsequently been dubbed "the most colorful mineral in the world". The most common colors are purple, blue, green, yellow, or colorless. Less common are pink, red, white, brown, black, and nearly every shade in between. Color zoning or banding is commonly present. The color of the fluorite is determined by factors including impurities, exposure to radiation, and the size of the color centers.
â?¢ Blue, black, gray or brown Barite is widely used for petroleum well drilling. The applicable Barite color is selected depending on the ore body.

• Kapok fibre
Kapok is a fluffy, silky yellowish fiber, similar in feel to milkweed or down.Kapok is similar to cotton in that both fibres are found around the plant seeds, rather than extracted from the stem or leaves.Individual fibres are 1.2 to 3.6 (0.47 to 1.41 inches)long, averaging 1.9cm (0.78 inch), kapok is a moisture-resistant, quick-drying, resilient, and buoyant fibre. Typical analyses indicate that the kapok fibers comprise 64% cellulose, 13% lignin and 23% pentosan.The hollow core makes kapok very light, 8 times lighter than cotton by volume.During the war, kapok was employed for insulating tanks, for lining aviation suits, for filling floats of army assault-bridges, and generally for replacing cork wherever lightness, moisture-resistance and floating power were needed. Kapok is chiefly cultivated in asia; the kapok fibre important product of pakistan.
