vchin Fire Glass Diamonds Cobalt Blue — 10 lb Polished Tempered Glass for Gas Fire Pits & Tables

Bring a clean, low-maintenance accent to gas-powered fireplaces and outdoor fire features with these cobalt blue glass diamonds. Each 10 lb bag contains polished, heat-tempered glass that reflects light and hides burner components while resisting thermal shock. They’re intended for use with natural gas or propane burners and make an instant visual upgrade for patios, decks, and indoor fireplaces designed for glass media.

How will this cobalt blue fire glass change the look of my fire pit?

The deep blue facets catch and refract flame and light, producing a sparkling, modern appearance that contrasts nicely with warm fire tones. The polished finish creates a gem-like shimmer both when the fire is off and when flames dance among the pieces.

• Creates vibrant blue highlights around flames for visual depth.
• Polished, tumbled surface increases reflective sparkle.
• Conceals burners and piping while maintaining airflow.

Is this fire glass safe to use and will it break or smoke?

These glass diamonds are thermally tempered to withstand extreme temperatures and are manufactured to resist cracking, popping, or producing smoke under normal gas-fired conditions. They are non-flammable and must be used with a compatible natural gas or propane burner system.

• Thermally tempered to reduce risk of fracture.
• Non-combustible material that won’t burn or emit soot.
• Keep burner ports clear—do not cover or block flame holes.

How much coverage does one 10 lb bag provide and how should I layer it?

One 10 lb bag typically covers a 28–30 inch fire table with a shallow layer that showcases color while allowing proper gas flow. For deeper pits or fuller coverage, plan to order additional bags and layer glass no more than a couple inches over the burner for safe flame performance.

• Recommended for 28–30 inch fire tables per 10 lb bag.
• Use multiple bags for larger or deeper fire features.
• Layer glass evenly; avoid burying burner ports.

How can I style these glass diamonds beyond the fire pit?

The polished cobalt pieces are versatile decorative accents: mix them with other colors, scatter in planters, or create tabletop displays. They resist fading and keep a vivid hue outdoors or indoors in non-sparking decor situations.

• Blend with other vchin colors for custom palettes.
• Use in dry decorative bowls or garden accents (not directly on wood).
• Easy to rinse and reuse season after season.
