The making of soda lime glass is expensive to compare then recycle sodalime glass . Main component for making soda lime glass is silica. for melting silica required toomuch temperature & other component which soda lime glass required are also much expansive. but recycled soda lime glass required low temperature for melting to shape it again at low cost . so we recycle soda lime glass.

itis also called soda lime silica glass
Soda lime glass is made by melting the component ingredients in a glass furnace. The temperatures in the furnace can reach 1675 degrees Celsius.
by fusing sand soda and lime
NaCl + CaCO3 ->Na2CO3 + CaCl2
salica(sand), lime. FIRE and soda
soda lime is a solid and a fruit lime soda is a drink that is made from soda and lime together.
A typical glass is prepared from 75 % SiO2 and 25 % Na2CO3.

A Pyrex dish is made out of a special type of glass so that it can be used in the oven or microwave. It is made out of soda-lime glass to withstand high temperature.
Most glass is a mixture of silica obtained from beds of fine sand or from pulverized sandstone; an alkali to lower the melting point, usually a form of soda or, for finer glass, potash; lime as a stabilizer; and cullet (waste glass) to assist in melting the mixture.
Soda lime glass made from sand (silicon dioxide), soda (Sodium hydroxide or carbonate) and lime (limestone or other calcium source) The soda makes the sand melt about 2000F instead of about 3000F and the calcium makes it water resistant (sodium silicate is water glass and dissolves in water) Borosilicate is glass made from sand and boron compounds. The advantage is that it has a much lower coefficient of expansion (COE) which means it doesn't change size much when heated, which means it doesn't crack when heated. The disadvantage is that while it softens when heated in a torch, it doesn't flow much and needs to be heated hotter than soda lime. Boro is used for scientific glass apparatus and for art projects as well as cookware in the home. When you see someone working glass in a mall or arts showcase with a torch with a strong blue flame, they are working boro, in part because it can heat and cool without cracking with less care than is needed for soda lime.
Murano is the island in Venice, Italy where Moretti glass is made. Due to new ownership, the glass is now called "Effetre." Effetre is a 104 COE, soda lime glass. Vetrofond is another Italian soda lime glass that is 104 COE, and that factory is run by members of the original Moretti family. Neither Effetre nor Vetrofond is associated with Lauscha glass, which is made in Germany.
