Review: I purchased the American Fireglass Medium Lava Rock in black for our outdoor fire pit, and it works beautifully. The rocks are the perfect size—not too big or too small—and they distribute the flame evenly for a nice, natural look. They also retain heat well and make the fire pit more efficient. The color is deep black, which gives the fire pit a clean and modern appearance, and it hasn’t faded even after several uses. A big plus is that the bag came with consistent, high-quality rocks without excess dust or broken pieces. Overall, great quality and value—I highly recommend these for anyone setting up a gas or wood fire pit.
Review: I like to grow my orchids in lava rock.

## Features

- MEDIUM LAVA ROCKS: Our 1/2”-1” Lava Rock can be used on their own or as a filler in your fire feature. We recommend using lava rock as a filler if you have a deep fireplace or firepit. For a complete design, add fire glass on top to cover the fire rock thoroughly so it will not be detectable.
- FOR FIRE PIT, FIRE BOWL OR FIREPLACE: Because lava rock is economical, it is the perfect choice as the first filler that goes into a very large and/or dept fire feature to cover up the gas piping and tubes. Once the lava rock is spread the way you want it, add a layer of fire glass to create a truly astonishing design that will instantly become the focal point of your home or yard.
- LONG-LASTING: Lava rocks are volcanic so they can withstand the most extreme temperatures without any change in shape. They offer durability and provide a low maintenance and cost-effective natural element that looks great as part of your indoor or outdoor decor. They can be used with liquid propane or natural gas.
- GORGEOUS & PRACTICAL: It does a great job of covering the floor of a fire feature, effectively hiding the unseemly pipes and tubes which are often visible in gas fireplaces or fire pits. This makes lava rock a more preferable alternative to the more common ceramic logs and fire stones. It can also be used in planters, landscaping, ponds and gardening.
- QUALITY ASSURED: We sift, sort and pack all of our lava rock by hand. This way we can guarantee that they are top quality, can be used in a firepit. For optimal results, our recommendation is to pour a minimum of two inches of lava rock over the firepit burner, which allows the gas to filter evenly through the lava rock media.

## Questions & Answers

**Q: Can I use Lava Rock with Fire Glass?**
A: Yes! using small lava rock as a base layer is very cost effective. We recommend using small lava rock as a base to completely cover the burner and then adding 2" of fire glass depth on top of that.

**Q: Are these products safe for high heat?**
A: Absolutely. All of our lava rocks are rated for use in fire pits and fireplaces. Just make sure they are completely dry before lighting to avoid any popping or cracking.

**Q: Do I need to replace lava rock over time?**
A: Yes. Lava rock can deteriorate after a few seasons due to weather and heat. Check it annually and replace as needed for best performance.
