Golden embers, sometimes called magic dust, are used in B-vent & direct vent gas appliance fireplaces. This product is dusted on the mineral wool embers and helps add that golden glow to the flame. Replacing the golden embers and mineral wool, should be part of your annual maintenance routine, along with cleaning the glass.
This product comes in a powdered form (carbon powder) and is added sparingly to the ember wool in a gas fireplace, to give the clean burning blue flame an orange glow that mimics wood burning. Please follow the instructions for placing the ember material in your owner's manual, and never block the ports on a gas burner.
