Often starting thousands of miles from the ocean, rocks slowly travel down rivers and streams, constantly breaking down along the way.

What are two facts about sand?
Sand is a mixture of very small pieces of different rocks or minerals. It is the same minerals from which those pieces are broken, such as granite and feldspar. Sand is gritty to touch. It is a naturally occurring granular material composed of finely divided rock and mineral particles.

How did sand turn into glass?
The chemical process of creating glass is undergone by heating quartz sand, also known as silica sand, to temperatures above 3,090 degrees Fahrenheit until it melts into a clear liquid. Once the sand is in liquid form, it is cooled and undergoes a transformation that doesn’t allow it to fully turn to a solid.
How did sand become white?
The color of sand grains comes from the original material that formed the sand. For example, white sand on tropical beaches is pulverized pieces of dead coral. (Coral skeleton is white because it is made of calcium carbonate, a mineral also found in chalk and human bones.)
Did glass came from sand?
Glass is made from natural and abundant raw materials (sand, soda ash and limestone) that are melted at very high temperature to form a new material: glass. At high temperature glass is structurally similar to liquids, however at ambient temperature it behaves like solids.
Can any sand turn into glass?
Believe it or not, glass is made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won’t find that happening on your local beach: sand melts at the incredibly high temperature of 1700°C (3090°F).
Can any sand make glass?
Silica sand is the primary source of silicon dioxide that is essential in the manufacture of glass. To be suitable for producing glass, there must be a very high proportion of silica (above 95%) in the composition of the sand. That’s why most sand deposits are not of sufficient purity for glassmaking.
