Black lava rock is 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 pebble shape and size. Perfect for outdoor natural gas and propane fire applications, black lava rock radiates heat at high temperatures with cracking or crumbling like other lava rock or cinder lava on the market. Warning: wet or damp lava rock may crack or burst upon rapid heat. Covering fire pit to keep lava rock dry when not in use is recommended.
