From our Fire Rock Collection, this Medium Fire Rock (averaging ¼"– ½") is used as an accessory to our fireglass. This is the most popular size fire rock. We recommend using fire rock as a filler if you have a deep fireplace or firepit. For a complete design, add fireglass on top to cover the fire rock completely so it will not be visible. We currently offer fire rock in 10 lb. bags, which is equivalent in size to 20 lbs. of fireglass.
