What is Fire Glass?
Fire glass is a type of specially tempered glass designed to be used in gas fireplaces and fire pits.

Fire glass serves both a functional purpose (helping distribute heat evenly) and an aesthetic one (transforming your fireplace into a modern focal point).

Choosing the Right Size, Type, and Color
When selecting your fire glass, size, shape, and color can play an important role in the overall look of your fireplace. That said, there are no hard and fast rules. Below are some things to consider as you start selecting fire glass for your hearth.
Size
In Gas Fireplaces, Fire Pits or Fire Tables there are numerous different burners on the market, each with a slightly different flame pattern. When adding fire glass, always consult the manufacturer's recommendations regarding media size. Obviously, if you're updating an electric fireplace, this is not a concern.
A general rule of thumb is that the larger the area you are covering, the larger your individual pieces of fire glass should be. For example, in a smaller traditional fireplace, fire pit, or fire table, you may want to consider using .25-inch crushed fire glass. The more individual pieces of fire glass in the hearth or fire feature, the more opportunity there is for light to be reflected.
Conversely, for a wider linear fireplace or larger fire pit, you may want to consider .5 inch or even .75 inch fire glass pieces. This tends to highlight the scale of your hearth and creates a more dramatic overall effect.
Regardless of the size of your hearth or fire feature, a mix of different fire glass sizes can be a good option, adding a sense of depth, interest, and complexity to your hearth.
Type or Shape of Your Fire Glass
As discussed above, Fire Glass comes in many different shapes and styles. Again, there are no hard and fast rules when it comes to selecting the shape of your fire glass, but below are a couple of considerations
For smaller traditional fireplaces, where you want to replicate a more natural look of embers, consider smaller-sized crushed or reflective glass in darker earth-toned colors. This will give you a look of embers with the added sparkle and ease of maintenance of fire glass.
For linear fireplace applications or larger fire pits, consider using larger molded fire glass or even fire glass beads. This tends to give your fire feature a more finished and refined look that matches the more expansive nature of the fire feature.
A mix of fire glass, like our Kaleidoscope Luxury Mixed Fire Glass, or our Luxury Mixed Fire Glass, are also a great options to consider. If you still don’t find your perfect match, consider creating your own custom mix with individual Enhance a Fire, fire glass components.
Color
Of all the different variables that go into selecting the perfect fire glass for your hearth, this may be the most difficult one to define since there are so many options to choose from. When selecting your fire glass color, you should also consider the color of any accent pieces like Fire Stones, Fiber Balls, Twigs, or Beach-inspired Mixes that you want to use in your fireplace, fire pit, or fire table
Below are a few suggestions to help with your selections
Blue, white, and Aqua Tones: Calm and coastal — perfect for pool sides or patios, Fire Pits, and fire Tables. It can also be used to create a stunning interior hearth.
Amber, Bronze and Earth Tones: Warm and cozy — ideal for traditional spaces. Gives a more natural look of traditional embers
Black, gray, and platinum: Sleek and modern — suited for minimalist designs. Great in linear fireplaces
Tip: For outdoor fire pits and fire tables, many designers recommend that you match your fire glass color to your outdoor furniture or stonework for a cohesive, designer look.
Installation and Safety Tips
Installing fire glass is simple, but following a few best practices ensures maximum performance and safety:
If the fire feature is gas, turn off the gas supply. If it is electric, make sure that the power is off before beginning
If the hearth has been used recently, make sure it is cool to the touch before removing old media or installing new fire glass
Remove old media (like lava rock or ceramic logs) and ensure the burner is clean.
Spread the fire glass evenly around the burner, without covering it completely.
Avoid piling too high, as it can restrict gas flow.
Test burn for a few minutes to confirm an even flame pattern and adjust as necessary

Design Inspiration and Applications
Fire glass isn’t limited to fireplaces — it’s a design statement that enhances any space:
Outdoor fire pits: Combine with fire shapes or ceramic stones for layered texture.
Indoor gas fireplaces: Use bronze or platinum glass to reflect indoor lighting.
Commercial spaces: Perfect for hotel courtyards or restaurant patios.
Pairing fire glass with Enhance A Fire! Fire Stones or Twig Sets creates rich visual depth, mimicking the natural complexity of a wood-burning fire — without the mess.
Cleaning and Maintenance
One of the best parts of fire glass is how easy it is to clean and maintain.
Ensure the glass is cool to the touch.
Scoop Fire Glass into a bucket of water mixed with mild dish soap.
Gently agitate the fire glass with your hand to remove any grime or debris.
Using your hand, scoop the cleaned fire glass from the bucket and place it on a towel
Allow to dry completely before replacing in your hearth
Pro Tip: An inexpensive plastic colander like the one shown below makes this process even faster. When you remove the fire glass from the soapy water, place it in the colander and then use fresh water to rinse. The excess water runs out of the colander, and you simply dump the fire glass on a towel, spread it out, and let it dry completely before reinstalling it in your fire feature.
