## Description

desertcart.com : Midwest Hearth Lava Rock for Fire Pits and Gas Log Sets, Black 5/8" to 1-1/2" (10-lb Bag) : Patio, Lawn & Garden

Review: Great looking lava rocks - Perfect size rocks for my large outdoor fireplace. I'm ordering another bag to fill in the very back.
Review: Lots of big chunks - I got this for aquarium use. It's doing well in a shrimp bowl, I added them a month or two ago and the shrimp and snails are healthy and so are the plants I tied to the stones. There is a good range of different sizes in the bag, including a lot of large chunks, like bigger than 2", and a lot of 1" chunks too. This bag will last me years.

## Features

- NATURAL VOLCANIC LAVA ROCK - Withstands extremely high temperatures without sustaining any damage or crumbling.
- NATURAL COLOR - No artificial color added. Natural black lava rock with hints of browns and grays.
- GREAT BASE LAYER FOR FIRE PITS - Use as a neutral bas layer, then top with logs or our beautiful fire glass!
- COMPLETE YOUR GAS LOG SET - Give your fire box a more complete look and fill that ugly floor with all natural lava rock!
- 5/8" TO 1-1/2" AVERAGE SIZE - Larger than our "granules", these give a slightly bigger look for outdoor fire features or large gas log sets.
