Gas-Powered

One popular technology used in fire pits is gas. Gas fire pits are powered by either natural gas or propane, providing a consistent and controllable flame. Gas fire pits are also easy to light and do not require any cleanup, making them a convenient option. However, they provide a different ambiance than a wood-burning fire pit and can be expensive to install.

Wood-Fueled

Wood-burning fire pits provide a natural and traditional ambiance and are famous for outdoor gatherings. They require less maintenance than gas fire pits and are often less expensive to install. However, wood-burning fire pits require regular cleaning and can be messy.

Bioethanol

These fire pits burn clean bioethanol, an alcohol made from plants that produce heat without any smoke or ash, and they don't need any external venting. They can be placed anywhere without needing a chimney or flue and are easy to install. However, they are warmer than wood or gas fire pits and may need to provide more heat for a large gathering.

Electrical

They are easy to install and do not require any venting or fuel. Electric fire pits are also easy to control and can be ignited or put out by flipping a switch. However, they provide a different ambiance than a wood-burning or gas fire pit and may need to provide more heat for a large gathering.

What is Fire Glass?

Fire glass, also known as fire beads or fire pit glass, is a popular alternative to traditional firewood for fireplaces and fire pits. This beautiful and versatile product can add a modern and sleek look to any outdoor living space, creating a stunning visual display as the flames dance through the glass.

Benefits of Fire Glass

There are multiple benefits of fire glass, including;

  • Clean and low-maintenance nature – Unlike firewood, fire glass does not produce ash or creosote buildup, which can clog chimneys and create a fire hazard. It also doesn’t produce any smoke or unpleasant smells, making it an excellent option for people with allergies or sensitivities.
  • Durability – Fire glass is manufactured using tempered glass, designed to withstand a fire's high temperatures. It’s also resistant to weathering and fading, making it an excellent option for outdoor use.
  • Diversity – Fire pit glass rocks come in various colors, shapes, and sizes, which makes it easy to find a style that complements any outdoor decor. Some popular options include clear, blue, green, and amber-colored glass. Some manufacturers also offer a variety of shapes, such as cubes, diamonds, and even crushed glass.

Selection and Installation Tips for Fire Glass

When choosing fire glass, it's essential to consider the size of your fire pit or fireplace. It is recommended to use a depth of at least 1 inch of fire glass to ensure proper airflow and combustion. Choosing fire glass specifically designed for fire pits and fireplaces is also vital. Regular glass can crack or shatter due to the high temperatures.

Installing fire glass is easy and can be done in a few simple steps. First, remove any existing firewood or other materials from your fire pit or fireplace. Next, spread a layer of fire glass over the bottom of the fire pit or fireplace. Finally, light the fire and enjoy the beautiful visual display as the flames dance through the glass.

What is Fire Wood?

Firewood is a traditional and natural fuel source for ages to provide warmth and ambiance for outdoor gatherings. Many different types of firewood are available, each with unique characteristics and benefits.

Types of Firewood

Hardwoods, such as oak, maple, and hickory, are known for their dense and durable nature. They burn hot and long, producing a consistent and steady flame, and they also produce less creosote buildup in the chimney than softwoods.

Softwoods, such as pine and cedar, are another popular type of firewood. They are known for their fast-burning nature and tend to ignite faster than hardwoods. They are also less dense and produce less heat than hardwoods.

Tips for Using Firewood

When choosing firewood, it's essential to consider the moisture content. The appropriate moisture content for firewood is between 15-20%. Wet wood will burn poorly and create much smoke, while wood that is too dry will burn quickly and produce less heat. It's also important to consider the species of tree. Some species, such as elm and willow, contain more moisture and can cause creosote buildup in your chimney.

Properly seasoning and storing firewood is also crucial for optimal burning. To allow for proper drying time, firewood should be cut and split 6-12 months before use. You should store it in a well-ventilated area, off the ground, and cover it to protect it from moisture.

When using firewood in a fireplace or fire pit, it's crucial to create a proper fire lay. A fire lay is the arrangement of the logs in the fireplace or fire pit. The traditional fire lay, also known as the "tepee fire lay," is where the logs are arranged in a teepee shape with kindling and paper at the bottom. A fire screen or spark guard is also important to protect against flying embers and sparks. And never leave a fire unattended.

Fire Glass vs. Fire Wood

Firewood and fire glass are both popular options for fireplaces and fire pits, but they have some key differences that make them suitable for different situations and preferences.

Visual Aspect

One of the most significant differences between firewood and fire glass is the visual aspect. Firewood provides a traditional and natural ambiance, with the flames licking up the wood and the crackling and popping sounds that many people associate with fire. Fire glass, on the other hand, provides a modern and sleek look, with the flames dancing through the glass and creating a beautiful visual display.

Maintenance Needs

Another difference between firewood and fire glass is the level of maintenance required. Firewood requires regular cleaning and maintenance, as ash and creosote buildup can clog chimneys and create a fire hazard. Fire glass, however, is much cleaner and requires less maintenance, as it does not produce ash or creosote buildup.

Costs

Regarding cost, firewood is generally less expensive than fire glass rocks, but the price can vary depending on the type and quality of firewood and location. Fire glass can be more expensive upfront, but it lasts longer and requires less maintenance, which can offset the initial cost over time.

Heat Output

Another difference between firewood and fire glass is the heat output. Firewood burns hot and long and produces a consistent and steady flame, making it suitable for larger outdoor gatherings. Fire glass, on the other hand, produces less heat than firewood and may not be ideal for large gatherings or freezing weather.

Safety

In terms of safety, fire glass is generally considered safer than firewood, as it doesn’t produce flying embers or sparks. However, fire glass can get extremely hot, so it's vital to use fire-rated glass and not touch it when it's in use.

Parting Shot

Firewood and fire glass are both popular options for fireplaces and fire pits, but they have some key differences that make them suitable for different situations and preferences. Firewood provides a traditional and natural ambiance, while fire glass offers a modern and sleek look. Firewood requires regular cleaning and maintenance, while fire glass is much cleaner and requires less maintenance. Firewood burns hot and long, producing a consistent and steady flame, while fire glass does not produce as much heat. Both have unique benefits and drawbacks, so consider your preferences and needs before deciding.

Conclusion

Is Lava Rock Or Fire Glass Better For A Propane Fire Pit?

Propane fire pits are popular for good reasons—from their affordability and safety to their all-year reliability. If you’re planning to install your own, it’s important to think about which media type you’ll use. Without the right media, heat won’t be evenly distributed, flames will look fake and your setup will be unsafe.  Let’s cover two of the most popular propane fire pit media options—lava rock and fire glass.

Lava Rock Vs. Fire Glass

No matter which one you ultimately pick, the good news is that both options perform in extreme heat. That said, there are a few key considerations when choosing. 

Appearance

Lava Rock Appearance

Lava rock is naturally made from hardened, cool-over magma. It’s porous—meaning it has spaces or holes throughout—but that’s the only real consistency rock to rock. Even within a single group, each one will vary to some degree in size, shape and color. So if you’re a perfectionist or can’t stand for things to be out of sync, this option is not for you. Color choices include subtle, earthy, non-reflective variants of blacks, reds and browns. 

Fire Glass Appearance 

This tempered glass—meaning it’s exceptionally safe and tough—is made by a number of different companies. Fire glass comes in a variety of colors, cuts and sizes, so for propane fire pit customization, it definitely has the edge over lava rock. Colors include more natural options like blacks and browns or more extravagant ones like blues, greens and reds. No matter which you opt for, fire glass will always have a smooth feel and reflective finish. 

Durability and Cost

Lava Rock Durability and Cost

Lava rock has a typical lifetime of 1-2 years (depending on how often it’s used) with no real maintenance needed otherwise. Compared to a propane fire pit that uses fire glass, you’ll have to do much more regular replacements. So even though lava rock may initially be a bit more cost-friendly than fire glass, expenses will add up over time. 

Fire Glass Durability and Cost

Since fire glass is expertly manufactured, there is no predetermined lifetime, with years and years of use all but guaranteed. Even more so than lava rock, it’s incredibly resilient to both damage and color warping. As long as it’s used as intended, there’s no risk of any damage or hazards. The only byproduct you’ll occasionally have to clean up is some soot. And while it typically costs a bit more than lava rock, it’s well worth the investment for your propane fire pit’s long-term use. 

Heat Radiance 

Both lava rock and fire glass help transfer heat from the propane fire pit to the area around it, but it’s not a close fight. Fire glass radiates heat about 3-4 times more efficiently than lava rock.
