Rock Wool Glowing Embers For Gas Logs

This is a 4 oz. bag of replacement rock wool glowing ember material for use with vent-free gas logs and fireplaces (can also be used with direct vent units as well). Do not use this product if your fireplace was not designed to have glowing embers. This is enough to cover your log set many times so do not install too much of this product or it will cause your fireplace to soot.
