Crushed fire glass is a chunkier version of our other fire glass offerings. It is similar in size to the gravel you may find in a driveway, but far more beautiful! The size of the pieces help to concentrate the color. In the case of Cobalt Blue, that results in an intense blue that "wows" day or night.Celestial fire glass is made from a premium, tempered glass and finished with a proprietary method that produces a glossy shine. We never dull the surface by tumbling the glass.High-quality glass safeguards our fire glass from cracking or loss of color when exposed to high temperatures. It will maintain its beauty fire after fire. And you can count on our fire glass to be safe and non-toxic. It does not emit chemical smells or release poisons into the air.Other fire glass is shipped in plastic bags that can tear, or rough up the glass surface. Instead, Celestial uses a 3-step packing process starting with a sturdy jar. This keeps the glass secure. Then it's placed in a protective internal structure before being sealed in the exterior box.The larger size of crushed fire glass makes it perfect for hardscapes, water features or as a vase-filler. It also creates larger air pockets when used in a fire pit, which results in larger flames.Celestial Crushed Cobalt Blue fire glass is so stunning, it's easy to make a statement wherever you decide to place it.
