TERRAFIRMA Rock Products, Black – Glassy – Volcanic Lava Rocks – Porous TERRAFIRMA Rock Products brings you these naturally occuring lava rocks sourced right here in the United States of America. These rocks are heat resistant. They were formed over millennia as magma rose to the Earth’s surface and cooled as gasses made their way through the cooling rock. This gives the rocks their porous surface. They are perfectly suited for your outdoor or indoor gas fireplace and are a natural and inexpensive alternative to fire glass. They serve other purposes as well. TERRAFIRMA Lava Rocks add paramagnetism and moisture retention to soils. Aquariums, fish tanks, fairy gardens, and terrariums are also a great use of our product. It is important that you keep TERRAFIRMA Lava rocks dry and free of moisture. When moisture gets into the rocks the heat of your gas fireplace will cause the water to expand and create steam which can affect your flame. UVA and UVB resistant. Choose TERRAFIRMA Rock Products for your gas fireplace accessories!
