What does sand and water make?

sand makes glass and glass make sand its a reverse psychology :)


Why is glass clear when sand is not?

Because glass is made from different materials and sand is a grain and is not able to look through.


Why does sand not dissolve in sea?

Sand, or silicon oxide, is fairly inert. It does not dissolve in water. Sand is mostly the same material as glass. So it does not dissolve any faster than glass dissolves in cold water. Hydrofluoric acid is, however, another matter.


How is glass made?

Glass is formed by heating sand to its melting point. Objects are then either cast or blown to their desired shape and allowed to cool slowly Glass is made from a mixture of sand and other materials. Just regular sand can be made into glass, but it must be heated to about 3,000 degrees Fahrenheit. It's also possible to make glass out of sand, sodium carbonate, and limestone. Together, they can melt at a lower temperature and make glass. Traditionally it was mass with fine, high quality glass, cut into shape and ground down and polished until it was the correct shape, however with the advent of plastics, they are usually made from polycarbonate or CR-69 (allyl diglycol carbonate). well first they et sand. then they melt it in a smelter and add stuff like lead. after that they let it cool down and it makes glass. did you know glass is a liquid =D


How do you make glass in the sandbox?

Melt it. Sand is highly variable in its composition but most will melt between 500 and 1000C, with the individual grains fusing together into glass. Fulgurites are a type of natural glass formed by lightning strikes on sand. Obsidian is another natural glass produced by volcanoes.
