Crushed fire glass is a classic look that reflects the light in your fire pit or fireplace. This type of glass is made from crushing large pieces of glass instead of shattering thin panes. The process leaves a finished product that looks more natural, retaining more contours and character. These fire pit glass rocks will provide a radiant, eye-catching fireplace feature in your home or backyard. Imagine the flames dancing above these translucent stones as your friends and family gather around the fire.
