Rock Salt FAQs:
Where does Rock Salt come from?
It is the byproduct of dried up enclosed seas and ancient lakes. Currently companies extract this salt through a variety of methods. Our Egyptian rock salt largely comes from the Siwa oasis, one of the richest areas in Egypt and the world as far as halite. Not to mention, Siwa salt boasts a 99.2% purity level.
How does rock salt melt ice?
The science behind this is quite simple really. When added to water, rock salt lowers the freezing point by 20-30 degrees. This in essence, makes it so that ice does not form as it would should water stand alone (unmixed with rock salt). So it is not melting the ice per se; rather, our Egyptian rock salt prevents the formation of the bond that would otherwise occur between pavement and ice.
