Celestial fire glass looks so sparkly because it undergoes a vibrating/screening process to remove the small, sharp pieces that would otherwise scratch the larger pieces, dulling their surface. Then, other undesirable pieces that don't meet our standards are removed manually.This painstaking process, in addition to the mirrored backing, creates a tempered fire pit glass with a sparkle that is more intense than other brands offer.Celestial fire glass is also engineered to be heat-resistant and tempered for safety. It will not crack or pop from exposure to intense heat. It also maintains its color and will not fade over time, making it perfect for long-term use.The Moonlight Platinum Reflective is a neutral color, but it provides a bit more warmth than our whites. Just like a glass of champagne, it has just a hint of a deep golden color for a feeling of luxury.And, with our easy-to-handle, 10-pound jars, you can buy exactly what you need, and it will always arrive in great shape.
