About Bamboo Salt
Bamboo salt (jugyeom) was developed by Korean monks over 1,000 years ago. The process involves filling a three-year-old bamboo trunk with Korean west coast sea salt, sealing it with natural yellow clay, and roasting over pine wood fire. The bamboo burns away and the process is repeated. Premium 9x bamboo salt is roasted nine times, with the final firing at temperatures exceeding 1,000°C, melting the salt into a liquid that solidifies into a purple-grey pillar.
Best for: Korean BBQ, Kimchi preparation, Traditional medicine, Toothpaste ingredient, Health supplement.

Rock salt deposits exist on every continent and range from a few meters to thousands of meters thick.
