Buying Guide
What color and size should I choose?
Color choices like cobalt blue or pacific blue create striking effects. Sizes around 1/2 inch to 3/4 inch balance heat distribution and coverage. Smaller beads spread more evenly but may require more material to fill the burner area.
Is fire glass safe for gas and propane?
Most fire glass is designed for propane and natural gas. Look for industrial-grade tempered glass rated to withstand temperatures up to 1300°F for long-term use, with no smoke or odors.
Maintenance and cleaning
Fire glass requires low maintenance. Rinse with a vinegar and water solution to restore luster. Avoid using harsh cleaners that could etch or dull reflective surfaces.
Installation tips
Pour glass evenly over the burner, keeping holes clear. Some products are thicker or larger; plan for coverage accordingly. For outdoor setups, select beads that resist weathering and maintain color.
Safety considerations
Follow your fire table manufacturer’s guidelines. Do not place glass in areas not designed for glass beads, and avoid covering ventilation or control openings. Use wind guards if recommended to reduce heat dispersion to nearby surfaces.
