Most of us are familiar with the use of rock salt to de-ice a location and offer some traction to make it less slippery however have you ever wondered where the rock salt stems from, how it works and how to use it efficiently? Right here is some background info about rock salt and exactly how best to keep and disperse it so you can stay safe during the winter months.

Rock salt used for de-icing is generally sourced in the UK from salt mines in North West England. The clinical term for rock salt is halite and this certain salt differs from other kinds of salt due to the fact that it is classed as a rock instead of a mineral. The salt is formed when big bodies of water that contain salt evaporate leaving the rock salt behind. The salt then becomes buried over time, which is why it should be extracted in order to retrieve it. In fact the salt that is extracted in Britain dates back some 250 million years ago when the waters were surrounded by desert!
Salt thaws ice by lowering its freezing point. When you add salt grains to water the freezing point will certainly continue to lower until the salt can easily no longer liquefy. In a lab this happens at around -21 degrees Celsius but when used out on the streets to thaw ice this freezing point is much greater at around -9 degrees Celsius. If temperatures fall below this then the salt itself will certainly begin to freeze becoming inadequate. As soon as the rock salt has actually been dispersed on the ice and thawed it the freezing point of the water will stay much reduced so offered temperatures do not fall too reasonable it will additionally prevent the ice from re-forming.
When saving salt it is very important to remember that the salt will freeze strong at temps below -7 degrees Celsius so it may be best to keep it indoors or in a garage that will not be too cold. A grit container is generally the safest means to store salt because it is specifically produced from non-corrosive polyethylene. A big handful of rock salt per square metre should provide some traction although for areas of a high footfall you could require a little more. Attempt to make sure that the salt is dispersed evenly using a shovel or spreader and ensure the snow and ice has actually been cleared as much as feasible prior to dispersing.
