Buying Guide

Match pellet size to burner design

Most indoor propane fireplaces work best with 1/2-inch to 1-inch glass; smaller pieces can shift into burners while oversized pieces may disrupt flame patterns

Prioritize tempered, heat-resistant glass

Choose fire glass labeled for high temperatures and tempered manufacturing to resist cracking or popping when exposed to propane flame

Consider finish and color for flame appearance

Colors like mint green, blue, or mixed Bahama tones change how flames reflect; pick a color that complements your interior and desired flame look

Buy by weight, not volume

Fire glass is sold by weight (commonly 20 lb bags); estimate fireplace cavity volume to determine how many pounds you need rather than relying on bag count

Check compatibility with indoor propane use

Confirm the glass is intended for fire pits or decorative fireplaces and that your fireplace manufacturer permits loose glass on the burner to avoid airflow or safety issues
