There are several factors to consider when comparing fire glass with lava stone for gas fire pits. For instance, aesthetics, heat distribution, maintenance, and cost. This article will explore these points while highlighting the cautionary note that fire glass can trap propane, necessitating careful consideration when using it with propane fuel:
- Fire Glass: Fire glass, also known as fire beads or fire crystals, is available in various colors and shapes, creating a modern and elegant appearance. It reflects and enhances flames, making it an excellent choice for those seeking a contemporary and decorative look. However, it’s crucial to exercise caution when using fire glass with propane fuel that propane is heavier than air. If one layers on too much glass you can effectively trap the propane should one have a leak as it sinks into the fire pit and trap the propane, risking ignition. Natural gas is lighter than air and as opposed to propane it does not sink.
- Lava Stone: Lava stone provides a more rustic and natural look, available in earthy tones like black, brown, and red. While it may not offer the same variety of colours as fire glass, lava stone can complement outdoor and rustic settings well.
- Fire Glass: Fire glass does not absorb heat and efficiently and therefore does not reflect the heat produced by flames until the unit has been on for some time.. Once glass is heated up it tends to “hold” the heat for an extended period after the fire has been extinguished. This means you have to be wary of using fabric covers until you are assured that the fire pit is cold to the touch to avoid burning your cover.
- Lava Stone: Lava stone absorbs and retains heat, providing a gradual release over time. While contributing to a cozy atmosphere, it might not distribute heat as efficiently as fire glass and it will cool down faster than fire glass.
- Fire Glass: Fire glass is generally low-maintenance, producing no ash, soot, or debris. Cleaning is relatively easy, involving rinsing or wiping down. However, caution should be exercised when cleaning around propane connections.
- Lava Stone: Lava stone may accumulate ash and debris over time, requiring regular cleaning to maintain its appearance. While it may demand more effort compared to fire glass, it’s essential to exercise caution with propane connections in both cases.
- Fire Glass: Fire glass is much more expensive than lava stone, with costs varying based on type, color, and brand. Despite the higher cost, many find the aesthetic benefits and low maintenance worthwhile.
- Lava Stone: Lava stone is generally more budget-friendly than fire glass, making it a more economical choice.
- In summary, the choice between fire glass and lava stone depends on personal preferences, budget, and the desired aesthetic. Exercise caution with fire glass and propane fuel, taking necessary precautions to ensure a safe and enjoyable outdoor experience.
