Review on 10 Pounds Cobalt Blue Recycled Fire Glass For Natural Or Propane Fire Pit, Gas Log Sets - Mr. Fireglass by Tim Purdie

Do not waste your time or money on this product unless you want black glass. The wife is pretty upset at me now that the blue glass pieces are all black. I rinsed and glass pieces before using them and they sparkled beautifully until I turned on our gas fire pit. As soon as the fire started, any blue glass that came in contact with fire immediately turned black. This is not the high quality that it is advertised to be. I gave it 2-stars for the fact that the pieces are pretty uniform in size and safe to handle without cutting your hand. However, the glass will darken as soon as you turn on the fire the first time.
