Having a fire pit in your backyard adds warmth and character to any space and creates the perfect atmosphere to enjoy time with family and friends all year. While glass fire pits are a bit more pricey, many people wonder if they can create a DIY version themselves by utilizing glass marbles in their fire pit. 

There are many types of fire glass that you can add to your fire pit, but ensuring that you use the right kind of glass is the difference between a warm fire and a disaster. Regular Glass Marbles are not a smart option because they are not created to withstand long periods of heat or out of tempered glass. You can also put your family at risk with not being confident of what that glass is made out of, releasing various chemicals into the air, and risking the marbles cracking or exploding from too much heat. 

This article will break down great options to utilize glass in your fire pit as well as why only certain glass should be used and the various options you have to add style to your fire pit. 

Can you use Glass Marbles in a Fire Pit

There are a variety of fire pits that you can add to your outdoor living area, and one type that has gained in popularity are those that utilize glass. The glass adds a stunning sparkle as your fire crackles over it and creates a beautiful ambiance to your space.

Because a glass fire pit with fire glass can be a bit more expensive, people always wonder how they can make their own for cheaper. While there are many things you can DIY in your home and yard, utilizing glass that is not made for fires can put you and your family at risk of inhaling chemicals. 

The main way you can be sure whether or not you can use glass in your fire pit is whether or not it is tempered glass. Tempered glass is used in a variety of ways, but it is made up to four times stronger than regular glass and can withstand heat up to 470 degrees.

What Glass Should Not Be Used in a Fire Pit

When it comes down to it, there is a specific glass that is created for use in your fire pit. When you stray away from fire glass and attempt to use other types of glass, you risk hazardous materials going into your air from the glass melting down. 

There are specifically created fire glass marbles that are a great option to know you are using a safe item in your fire pit. Fire glass marbles also come in a variety of colors that you can choose to match your home’s aesthetic and style. 

Many of the fire glass marbles and stones are created from tempered glass that is made to withstand a variety of situations and holds heat well. 

What is Fire Glass

Fire glass is glass that is specifically created to be able to withstand incredibly high temperatures. Fire glass comes in a variety of colors and is made to not melt or explode when it comes into contact with high heat. There are multiple options for fire glass, and each has its own pros and cons. 

Reflective Fire Glass

Reflective fire glass in your fire pit gives off reflective colors as your fire burns above it. An important thing to note is that reflective fire glass is typically not cut smoothly, so the edges can be very sharp. 

Recycled Pit Glass

Recycled pit glass reuses glass bottles and other types of glass to reuse in your fire pit. The glass is melted down and repurposed into a glass that you can use to add some style and charm to your fire pit. 

How to Properly Use Fire Glass

Fire Glass is not flammable, meaning it is not what provides you with the flame for your fire pit. Typically, fire glass is paired with a fire pit that utilizes natural gas to provide a flame that reflects off of the glass that surrounds it. 

Fire Glass is simply an added style piece to your fire pit, providing a visually appealing addition used only for decoration. Natural Gas and propane are your top two options for the fuel you need to have a flame on your fire pit, and both have their pros and cons. 

Overall, natural gas is a cleaner option when using fire glass in your fire pit because it does not leave a residue over your glass. Propane holds a good amount of heat under the fire glass, which can prove to cause many issues over time and can even crack glass created for fire pits. 

How Much Fire Glass Do I need for a Fire Pit

The amount of fire glass you need for your fire pit will greatly depend on the size of your fire pit and whether you are using natural gas or propane. 

When you are using natural gas, you can fill your fire pit with two to three inches of fire glass and create a well-rounded and streamlined look. Because propane holds more height under the glass, it is recommended to only use around one inch of fire glass in your propane fire pit. 

If you have leftover fire glass, you can always add it to your garden bed or on top of planters that are placed around your back porch. With the versatility of fire glass, it can be used in various spots all over your yard if you bought too much or didn’t need nearly as much as you initially thought. 

Conclusion 

Fire pits that utilize glass can add style and charm to any space when used properly. Because there is heat involved, you should also be absolutely positive that what you are putting in your fire pit can withstand extreme heat. If you are trying to decide whether to purchase a fire pit that utilizes propane or natural gas and fire rocks, it is important to add up the pricing of each as they are typically more expensive than a standard fire pit. 

When it comes to glass marbles you may find at the store, they typically are not created to hold up against a lot of heat. If you decide to go the DIY route and put glass that is not approved for fire pits, you risk putting harmful chemicals into the air, and you risk the rocks exploding from too much heat. 

It is also important to remember that fire glass is not flammable, so you must always have another form of fuel such as propane or natural gas. Propane heats under the glass, so you will only need about an inch of glass versus natural gas; you can add up to three inches.

While fire marbles are more expensive than typical marbles, spending a little extra money will give you peace of mind and will allow you to enjoy a warm fire without worrying. Fire pits with fire glass are the up-and-coming option to enjoy a fire without compromising style and charm. Choosing a well-made fire pit and the correct fire glass will set your backyard up for success and provide a perfect spot for family gatherings.
