Fire pit glass is made using tempered glass. Unlike competitors that tumble thier glass we have always used a different process. Tumbling glass results in a very scratched surface which greatly reduces the reflective qualities of the glass. Our handcarfting process ensures a much higher quality finish and flawless reflective fire pit glass crystal surfaces. Does this really make a difference or is this just a sales pitch? Take a pair of sunglasses for example: once your lenses get scratched they are obviously flawed, the same rule applies to fire pit glass that has been tumbled which leaves heavy scratches on the mirrored reflective surfaces as a result of the tumbling process. Ultimately tumbling glass will cloud the surface of glass. Our fire pit glass is hand crafted which preserves the reflective quality and surface of the glass resulting in a much higher shine, sparkle and overall reflection.
