Purchased these for the Christopher White outdoor fire pit grill and to coordinate with our new swimming pool tile colors. We were not sure if one bag would be sufficient, and if you were going to replace the lava rock that was included with the firepit, you would need at least 2 bags. So, we just filled the bottom layer with the lava rock (not using all that was supplied), then spread this Firepit Glass over it. It looks quite nice when the gas flame is turned on. At first it appeared to be more turquoise combo in the online photo, but actually has quite a few deep cobalt blue glass pieces mixes with very light green tinted glass. However, when it is lit up, it does glow with more teal and turquoise which is exactly the effect we wanted. Glass is a bit pricey, but with discount coupon and spreading atop of the lava rock, it's worth it!
This is a great buy. Sturdy and well constructed. Since it is not one sided, people can sit all around it enjoying the heat and beautiful flame. It holds several logs at a time and to stoke the fire, you simply pull back the screen.
