Glass - Ordinary glass is a mixture of sodium and calcium silicates and is made by heating a mixture of sand (essentially SiO 2 ) with sodium carbonate and calcium oxide in a furnace at around 1700K and cooling rapidl..

Since CO 2 is liberated in the initial stages, frothing is a common observation. All the CO 2 is driven out on continued heating and a clear viscous fluid mass is got. It is then poured into moulds of various shapes or stamped with die (a device for stamping, cutting, or moulding mater..

The unusual brilliant shine of diamond makes it an invaluable precious stone in jewellery. Making high precision cutting tools for use in medical field. Because of it's hardness it is used in manufacturing tools/cutting drills for cutting glass and ro..

Applications of Polarized Light - Polaroids are used in sun glasses. They reduce the intensity and the glare by cutting down the horizontally polarized light. Polarized light is used in photo elastic stress analysis. For 3-D view, special type of glasses, which have po..

Oil or molten fat is taken in an iron pan fitted with a stirrer. It is then treated with lye (any strong alkaline solution, like potassium hydroxide used for washing or cleansing). Stirring is continued till the soap begins to set. After solidification in frames, it is cut into slabs and..

Mirage is an optical illusion, which occurs usually in deserts on hot summer days. On such a day, temperature of air near the earth is maximum and hence is rarer or lighter. The upper layers of air, which are relatively cool, are denser. A ray of light from the top of a tree travels fro..

Hold a bottle cork in one hand firmly and cut a thin slice with the help of a blade. Place the section in a drop of water on a glass slide and observe under a microscope. You will find cells, which are box-like and closely packed togethe..
