glass
Sand isn't used for melting snow. Sand is used for traction.
Sand does not affect the melting point of a substance since it does not mix with the substance during the melting process. Sand is typically heated separately and can act as a heating medium but does not directly influence the melting point of the substance being melted.
Sand is Silicon Dioxide or Silica. It's composition varies a bit, since "sand" isn't pure silica. That said, it melts at around 1650 degrees Centigrade +/- 75 degrees or so for impurities. Roughly 3000 degrees F.

Assalam walykum, guys as well as I know Soda Asia Sodium Carbonate reduce the melting point of silica sand about 1600 degrees to 750 degrees, but I don't know what is the percentage of it......
I think road salt it made of salt, gravel and sand. The salf lowers the melting point of the snow/ice, so therefore melting it, and the sand and gravel give a car grip.
It is the principal component of glass making
Glass is silica dioxide. It is made by melting silica sand.
Sand is made up of billions of small rocks which require a very large melting point. Since nowhere in the world can get up to a temperature hot enough to reach the melting point, the sand doesn't melt.
Some chemicals used in glass production include silica sand (SiO2), soda ash (sodium carbonate), limestone (calcium carbonate), and cullet (recycled glass). These chemicals help to lower the melting point of silica sand and improve the durability and clarity of the glass.
If the sand particles are small enough that they stay floating instead of all sinking to the bottom, then it will work. This reduction in melting point is because of messing with the hydrogen bonding of the water, so anything that stays at least partially dissolved will lower the melting point.
