We offer this Finishing Touch Fireglass in 1/4″ Crystals. Glass is tempered and will not melt, discolor, degrade or produce toxic fumes and is guaranteed for life. Finishing Touch Fireglass is bright, brilliant and clean. It is NEVER tumbled. Tumbling of the glass scratches the glass and leaves the glass dull. This Fireglass can be purchased in a Classic or Metallic Finish and is sold by the pound (Reference firebowl descriptions for fireglass quantities required). If using with Propane, use darker colors since propane can soot lighter colors of glass. Each order is packaged and shipped from Finishing Touch.
