Why is limestone used for making glass?

Answer 1

because its a cheap and there is plenty of limestone

Answer:

Limestone is one of the primary components of glass. When limestone (calcium carbonate CaCO3) and lime (CaOH)is heated with silica sand (SiO2) it makes a fluid solution not crystallize when it is cooled. This material is glass.

Answer 2

Glass is made by melting silica sand, limestone and soda ash in a furnace at around 1,500°C.

Glass is made from sand and limestone. Limestone is added before the heating process in which the glass is formed. The limestone in the glass helps protect it from weathering. After the heating process which is done in cool conditions a soda-lime-silica glass product is formed, which is glass, as we know it. Glass is used in almost everything: glasses, windows, mirrors, computers etc.

Answer 3

* 'The hard shells of living things produce some kinds of limestone. How dopes limestone form? Limestone forms in the ocean, many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. There shells pile up as sediments on the ocean floor. It turns into calcite cement after millions of years which pieces together forming limestone. Limestone is also known as chalk. * Over time coral buried by sediments will form into limestone (like the animal shells).

Answer 4

You can't really say that glass is made from limestone. Glass is made from a range of different ingredients and the ingredients in different types of glass vary. The ingredient all glasses have in common is silica sand, so you could say that glass is made from silica sand! The main difference between glasses is the flux, so they're named after the flux contained in them. Flux envelops each grain of sand to lower the melting temperature. The most common type of glass is called soda/lime glass and the flux is sodium carbonate and lime. The lime is manufactured from limestone, so you can say "some glass uses the products of limestone as a flux". Other commonly used fluxes are boron (for borosilicate glass), lead and flint.

Answer 5

Limestone is a sedimentary rock made of dead animal shells formed deep down in the ocean; limestone also contains a large amount of calcium carbonate. Carboniferous limestone is a different type of limestone. It was formed around 350,000,000 years ago as a marine deposit in a warm, clear, shallow sea. The rock is well bedded and jointed. The cracks that separate the beds are called bedding planes and those that run down through the rock are called joints.

Glass is made from sand and limestone. Limestone is added before the heating process in which the glass is formed. The limestone in the glass helps protect it from weathering. After the heating process which is done in cool conditions a soda-lime-silica glass product is formed, which is glass, as we know it. Glass is used in almost everything: glasses, windows, mirrors, computers etc.

Answer 6

Glass is made from limestone and sand. Limestone is added just before the heating process to form glass to help protect it from weathering.

Answer 7

Limestone is combined with silica and soda ash and heated in a furnace at 1,700 degrees Celsius to make glass.

Answer 8

yes
