About Hawaiian Black Lava Salt
Hawaiian black lava salt draws on the tradition of incorporating volcanic elements into Hawaiian salt, which dates back centuries with alaea red clay. Modern black lava salt uses activated charcoal from coconut shells processed using volcanic heat sources on Hawaii's Big Island. The product was developed in the late 20th century as demand grew for visually distinctive finishing salts. The charcoal activation process creates an extremely porous carbon structure with high adsorptive capacity.
