What is Brown Rock Salt?
Brown Rock Salt is also known by the name, Halite. However, the majority of Rock Salt Suppliers, ourselves included, refer to this product as Rock Salt. You might have heard people referring to road salt or grit salt, these are other names for brown rock salt when used for de-icing purposes..
This leads really well into telling you what we use brown rock salt for. Rock Salt has a multitude of uses, but the main uses are for preventing ice and melting snow and ice on paths, roads and car parks. It's the stuff you find in grit bins at the side of the road and the salt speard on road out of gritting lorries.
There's a lot of history behind rock salt, but, the digestible version is: we source it from mines of ancient underground salt deposits and most importantly, the majority of rock salt is mined in the UK. This means it's quicker and easier to deliver it straight to your delivery point.

Where does Rock Salt come from?
Rock Salt comes under several different names, but, the main distinction is that, de-icing rock salt is a rock, rather than a mineral, showcasing the difference between rock salt and the salt you have in your kitchen!
Rock Salt can be found all over the world. It is typically formed by evaporation of salty water like seawater. Salt normally forms in deposits ringing dry lakebeds, inland marginal seas and in enclosed bays and estuaries' in arid regions of the world. In times gone by, very large areas of water evaporated and makde large amounts of rock salt. Marine sediments would then bury the salt. Halite is less dense than the marine sediments so it would push its way up through the sediments creating a dome like structure.
