Be generous to get the desired effect. ## Features - SMOOTH & ROCK-FREE FINISH OF IRGULAR LAVA - Unlike traditional porous lava rock, these stones move by hand to create a smooth, rounded shape with no sharp edges. The result is a clean, modern look that complements contemporary gas fire pits, fire bowls and gas log sets beautifully. - EXTRA LARGE SIZE 3-5 INCH FOR A DRAMATIC LOOK - Each stone measures 3-5 inches, making them ideal for larger fireplaces and outdoor fireplaces where smaller stones are lost. A 10lb box covers approximately a 12" x 12" area in a single layer - use 2-3 boxes for a full fire pit bed. - HIGH TEMPERATURE RATING IMPORTANT SAFETY NOTE - Made of 100% natural volcanic lava stone that withstands extreme heat without crumbling, cracking or fading.
