As the sun sets and the air cools, there’s nothing quite like the cozy warmth of a fire pit. However, have you ever considered adding a touch of sparkle to your flames with glass marbles?
With their vibrant colors and shiny appearance, these spherical glass pieces can create a unique visual appeal to your outdoor get-togethers. They also have many benefits that can enhance your overall fire pit experience.
Some of those benefits include increasing heat retention and reducing ash buildup. I will discuss this topic in detail in today’s article, so let’s dive right in.
Can You Use Glass Marbles in a Fire Pit?
The answer is yes, but with some precautions.
First and foremost, it’s important to use tempered glass marbles that can withstand high temperatures without breaking or melting. Regular glass marbles aren’t suitable for fire pits, as they can crack or explode when exposed to heat.
What is Fire Glass?
Fire glass is tempered glass designed for gas fire pits and fireplaces, engineered to endure high temperatures and retain heat.
Unlike standard glass, fire glass is resistant to melting, exploding, smoking, or accumulating soot. It offers a range of colors to complement your existing indoor or outdoor decor.
Once you ensure they’re tempered glass marbles, they can be safely added to the fire pit. The glass marbles will create a beautiful and mesmerizing effect as they reflect the flames and light up the area around the fire pit.
Additionally, glass marbles offer some practical benefits for fire pit users:
- For example, they can help to distribute heat evenly throughout the fire pit, resulting in a more comfortable and cozy experience for those sitting around the fire.
- Moreover, glass marbles can also help minimize the ash buildup in the fire pit. As the marbles move around with the fire, they can help to stir up the ash and prevent it from settling at the bottom of the fire pit.
However, it’s important to exercise caution when using glass marbles in a fire pit:
- Start with a few marbles and gradually add more as needed.
- Too many marbles can interfere with the airflow and create an unsafe situation.
- It’s also important to keep children and pets away from the fire pit when you add glass marbles.
Using glass marbles in a fire pit can be a unique and enjoyable addition to your outdoor living space. Still, taking proper safety precautions is important for a safe and enjoyable experience.
How Much Glass For Fire Pit?
Ensure you have enough glass marbles to cover the burner, keeping it out of sight.
Be cautious not to use too much, as it can cause performance problems. Avoid using too few, leaving the fire pit looking empty.
- If you have a custom-built fire pit with an open area under the burner, filling it with lava rocks is a cost-effective option to reduce the need for numerous glass marbles.
- If you have a standard-size fire pit, the space beneath the burner is typically smaller, making a filler unnecessary.
Here’s how to calculate the quantity of glass marbles for your fire pit.
How much glass marbles for a rectangular fire pit?
To calculate for a rectangular fire pit, use the length, width, and depth:
The amount of glass marbles (in pounds) can be determined by multiplying the width by the depth and glass depth, then dividing by 20.
For example, a 20″ x 10″ fire pit: 20 x 10 x 2 / 20 = 20 lbs.
How much glass marbles for a round fire pit?
For a round fire pit, use the diameter and depth:
The amount of glass marbles (in pounds) can be determined by multiplying the diameter by itself, then by the glass depth, and finally dividing by 24.
For example, for a 22″ diameter fire pit: 22 x 22 x 2 / 24 = 40 lbs.
It is recommended to have a depth of 2″ for most installations, with approximately 1/2″ of fire glass on top of the burner.
Glass marbles are typically sold in 10- or 20-pound packages, and it’s easier to add more later, so begin by adding a reasonable amount when filling the fire pit.
