Where Can You Use the Fire Glass Marbles?

Fire glass marbles can be safely used in a wide range of places. When using in a fire pit, you need to make sure that you read the instructions thoroughly as you would not want to use the glass marbles in a pit only meant to burn wood. That could potentially be dangerous.

Certain high-end fire glass marbles tend to be quite expensive. This poses a problem if you have a very deep fire pit. Thankfully, you can make use of specific hacks that will not only save you some bucks but also retain the aesthetic appeal of the glass marbles in the fire pit.

  • Quick and Easy Hack

For this hack, you will need to make use of lava rock. We recommend you try out the  Fireglass Black Lava Rock. These are available in a pack of 20-pound and sizes that range between  ½ to one-inch thick. These lava rocks are ideal for outdoor as well as indoor use and can be used with propane or natural gas.


The rocks are capable of withstanding extreme temperatures without getting damaged or crumbling into pieces. They are also durable, long-lasting, cost-effective, and need low maintenance thanks to its porous surface.

Once you put these lava rocks at the bottom of the fire pit, they will take a majority of the space, and then you can cover them up using the fire glass marbles. This will give an illusion that the pit is filled with marbles. This makes it a fantastic and cost-effective item.

You must make sure, though, that you separate the lava rocks and the glass marbles with a metal mesh sheet. This Stainless Steel Woven Metal Mesh is an excellent option for this.


Measuring at 40 x 7 inches, the sheet can easily withstand temperatures reaching as high as 1300-degrees Celsius. It is made using high grade stainless steel which is wear-resistant, durable, and has a long service life.

Having a mesh between the fire glass marbles and lava rock is an excellent idea as this mesh will make it easy when you need to remove the marbles and the lava rock for maintenance instead of it getting all mixed up together and becoming a big mess.

  • Versatility

The best thing about fire glass marbles is that they are very versatile. They don’t just need to be used in a fire pit or fireplace. These marbles are a brilliant addition to your home.

Since the majority of them are brightly colored, they make an excellent filler for plants or on a rock bed. There are countless ways you can make use of these marbles to elevate your landscaping.

We recommend using fire glass marbles in places where you would typically see dirt or rocks. You can use these marbles to line sidewalks or concrete patios. Its bright colors do a great job of adding another dimension to the design.

How Long will Fire Glass Marbles Last?

The duration of how long the fire glass marbles will last entirely depends on how it is treated. If they are taken care of properly, the marbles will last for a long time in the fire pit. The way these marbles are made ensures that they can hold up to those high temperatures.

While propane can cause some damage to the fire glass marbles, they can still be used. However, you will see some sort of cracking or changes in the marble’s color over time. If you don't replace them for a long time, the propane may end up causing the fire glass marbles to break and for its color to turn black as well.

If you are using propane, then we do not recommend using fire glass marbles that are light in color. The propane will alter the color of these marbles, and this will become very noticeable on lighter marble colors. Always opt for darker colors such as blue, dark green, black, red, and the like to hide this discoloration.

While it is true that the fire glass marbles will crack over use and time, it will still last longer when compared to traditional fire fuels. This is because these marbles are purely designed for decoration and not as a fuel type. This means that there is lesser stress on them and that you don’t need to replace them as often as you would do to things like wooden logs.
