The vibrant shades of fire glass add style to any gas fireplace or fire pit. The shiny shards come in almost every color imaginable, including blue, green, copper, gray, and multi-colored mixes. Ideal for both indoor and outdoor fire features, the small pieces of glass can reach extremely high temperatures without losing it bright color, cracking, or burning. But before you purchase fire glass, here are a few things you should know.

What is fire glass?

Fire glass is made from tempered glass intended for use in gas-burning fireplaces, fire pits, or fire bowls. This glass will shine bright as it reflects the flames of the fire or the rays of the sun, both making these pieces of glass sparkle. When it’s used as recommended, it can withstand temperatures up to 13,000 degrees without burning, melting, or losing its color. It is non-toxic and does not create smoke or messy soot and ash.

How do I use fire glass?

Fire glass belongs in outdoor fire pits and fire bowls or vented and non-vented fireplaces. We recommend covering the burner with a layer of cinders or lava rock that are 1" diameter or larger. Glass should then be used as a topping over cinders/lava rock to approximately 2” in depth. This helps save material and money while allowing for safer operation.

Fire glass is a great multi-purpose media. Use it to fill vases for a decorative flair or inside aquariums and fish bowls. You can also use it in landscaping, fountains, or rock gardens for improved outdoor aesthetics.

How much fire glass do I need?

Buying too much fire glass can get costly, so it’s best to estimate how much you need before you buy. Use the fire glass calculators on our website to measure square/rectangle, round/octagon, or standard firebox needs. You will input the fire feature’s width, depth, and height in inches. The calculator will output the total pounds required for your fire pit or fireplace. Remember, use less expensive fire media to fill the space, and then top it off with 2” to 4” of fire glass.
