Black Lava Rocks are uniquely formed when hot lava emitted from an active volcano meets the ocean and hardens on contact. The rocks are gathered from the lava fields in Indonesia and tumbled to create a consistent and more uniform shape and size. Perfect for outdoor natural gas and propane fire applications, Black Lava Rocks radiate heat at high temperatures without crumbling like other lava rock or cinder lava on the market. Warning: Wet or damp lava rocks may crack upon rapid heat. Covering your fire pit to keep lava rocks dry when not in use is recommended.
