Himalayan salt is a pink salt extracted from mines in Pakistan. Khewra is the most well known. Many years ago there was a sea in this area which then dried leaving salt deposits. This got covered by rock over the years. Some iron makes the salt crystals appear light pink. It’s very similar to the salt found in most kitchens. The Himalayan Pink Salt Co have a website selling salt for cooking, salt for your bath and salt lamps. You can also buy large amounts of salt for stores restaurants and other businesses on their wholesale service. (www.himalayanpinksalt.com)
