A client with a gas fireplace insert (Heat-n-Glo) wants to remove the ceramic ‘logs’ and have the flames emerge from crushed glass or ‘river rocks’ for a more contemporary look… a couple of questions…

• can regular crushed and/or tumbled glass be used instead of what’s sold specifically for fires (“fireglass”, etc.)?

• will removing the ‘logs’ reduce the heating efficiency… less radiant heat?

Thanks!
