Margo Garden Products Landscape Fire Glass adds a luxurious sheen to any indoor or outdoor setting, especially for landscaping projects that want to stand out from the rest. All glass pieces are gently tumbled to produce smooth edges ideal for landscaping. All glass is also tempered to withstand high temperatures, making it an alluring feature for outdoor fire pits. These glass pieces are created through an industry leading manufacturing process to ensure durable form and lasting color. The finished glass comes packaged in a hassle-free storage bag designed for easy handling. We recommend using decorative tumbled glass for fire pits, landscapes, aquariums, floral arrangements, water features, and to embed in decorative mosaics and stone works. Half-inch landscape glass is recommended over quarter-inch landscape glass for propane and natural gas fire applications. Landscape Glass is not recommended material for use in fire places.
