The Peterson Real Fyre Select White Sand (CS-10) can be used on the fireplace burner pan around your gas log burner for filler. Select White Sand allows the burner to stay cool and helps disperse flames for a realistic fire. These are ideal for filling a burner pan, adding to a gas log set, or laying a foundation for fire glass. The sand may only be used with natural gas vented gas logs. Includes one 10 pound bag.
