These Lava Stones are safe for use in fireplaces and fire pits. Available in four sizes: Small (1/2"- 1"), Medium (1"- 2"), Large (2"- 4"), and XX-Large (4"- 6"). Tumbled Lava Stones retain heat much better than logs, making them more energy efficient and cost effective. The same weight of lava rock fills more space than fire glass because of its density. Tumbled Lava Stones look great as an additional accent to fire glass, and also look great throughout any fire feature.

Product Protection

Lava Stone acquires minimal maintenance because it is used to replace gas logs and doesn't leave behind soot, dirt, or ashes. Stones can get dirty and dusty from outdoor debris. If there is an obvious build up of dirt you can scoop out the stones and wash it with dish detergent followed by a thorough rinse.
