Quarries For Raw Materials For Making Of Glass. Glass is completely a vitrified product which has no definite composition. The major ingredients form over 90 of all types of glasses are Lime CaCO 3, Sand SiO 2 and soda ash Na 2 CO 3.The raw materials used in the manufacture of glass can be broadly divided. into the following categories

Cer103 Notes Shelby Chapter 3 3-5 R.K. Brow Glass Making Note some oxides might come from more than one raw material SiO2 will be supplied by sand, feldspar, kyanite, etc. Need to keep track of all sources of all oxides Example of a batch calculation see Shelby pp. 32-33
Mar 25, 2009 S-glass fibers, developed for higher strength, are based on a SiO 2-AI 2 O 3-MgO formulation but contain higher percentages of SiO 2 for applications in which tensile strength is the most important property.. In the initial stage of glass manufacture, therefore, these materials must be carefully weighed in exact quantities and thoroughly mixed batched.
The raw materials and glass pieces are melted in a furnace and then shaped into moulds to make new bottles of different colours and sizes. New recycled bottles and jars are made in this way. In countries like USA, there are kerbside recycling schemes, which have specially demarcated boxes to collect glass
The key raw materials required to produce steel include iron ore fines and lumps and coking coal. Company has its captive iron ore mines at Vijay-II near Barajamda, Jharkhand. Coking coal and non-coking coal are procured from indigenous as well as foreign sources.
The materials extracted from the quarries contain large quantities of fibrous amphiboles these materials are used widely in the local building industry. The locality was described then as being too rugged and is a quarry for a fine stone similar to that of Portland there are also limestone quarries and a slate quarry.
GLASS-MAKING MATERIALS. During the last season several important glass-manufacturing districts Tiave been visited by Survey geologists, and careful investigation lias been made of the glass sands and other .raw materials used in the manufacture of this produc i. The results of this work are sum marized in the following three reports
The vast bulk of our built environment is formed from raw materials won from the earth by the extractive industries. Without the raw materials with which to build houses, hospitals, schools, factories, roads, etc., life would certainly be more basic and less comfortable than we presently experience.
This paper calculates the energy and raw materials required to produce glass containers in the U.K. in 1977 from raw materials in the ground. It is shown that the average energy requirement is 21.9 4.2 MJ per kg of saleable glass produced. The detailed breakdown of this overall energy by fuel type and by contributing operation is also given.
glass, and pressed and blown glass. Flat glass includes plate and architectural glass, automotive windscreens and mirrors. Pressed and blown glass includes containers, machine and hand-blown glassware, lamps and television tubing. In both categories a glass melt is prepared from silica sand, other raw materials such as lime, dolomite, and soda, and
The glass is finally cooled in a part of the machine called a lehr which is an important part of glass making since the glass can easily break if this is not controlled. The modern machines effect the glass making rate achievable, but this can be up to 75,000 light bulbs and 55,000 drinking glasses can be produced per day.

The majority of raw materials used to manufacture glass bottles are sand, soda ash, and limestone. For every ton of glass that is recycled 1,300 pounds of sand, 410 pounds of soda ash, and 380 pounds of limestone are saved. More facts about glass recycling - Earth911.com.
