How is Glass Made and What is it Made Out Of? Brennan
2020.8.13 In the past, glass was made by heating sand to 3090°F turning it into a molten liquid that is then shaped into glass products. When the molten sand cools, there’s a significant transformation in the material’s molecular structure. In scientific terms, this state is known as amorphous solids↗, and glass is one of the best examples of it.

The choice of aggregate is determined by the proposed use of the concrete. Normally sand, gravel, and crushed stone are used as aggregates to make concrete. The aggregate should be well-graded to improve packing efficiency and minimize the amount of cement paste needed. Also, this makes the concrete more workable. Refer to Demonstration 3

Filtration - Wikipedia
Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated. Filtration, as a physical operation enables materials of different chemical compositions to be separated.

Glass, how is it made?
2022.12.29 To create glass, sand is melted at extremely high temperatures, temperatures nearing 1700°C. When sand has reached its melting point, it begins to transform. The structure breaks down, where it is not a solid anymore, but not quite a liquid either. This allows glassmakers to be able to mould the material into the preferred shape.
