20lb Natural Lava Rock for Gas Fire Pit

Unique black lava pebbles are formed when hot lava from an active volcano meets the ocean and hardens upon contact. These pebbles are gathered from lava fields, tumbled, and shaped consistently, unlike other lava or cinder rocks on the market. They are sourced from Asia, with a size ranging from 3/4" to 1 1/2".

These lava pebbles have a variety of recommended uses, including walkways, outdoor gardens, fountains, planters, and creative interior/exterior designs. They are tumbled to create a more uniform shape and a unique appearance.

For rectangular fireplaces or fire pits, divide the length times the width times the height by 21 to determine the required weight of pebbles in pounds. For round fireplaces or fire pits, divide the diameter times the diameter times the pebble height by 26 to find the required weight of pebbles in pounds.

Overall, the unique formation and durability of black lava pebbles make them ideal for a variety of natural gas and propane fire applications, ensuring they will not crumble or break down over time.
