We've had the diamond shaped amber colored glass in our firepit for a couple weeks now and LOVE it. We haven't had any issues with popping or cracking like mentioned in other reviews. I ordered the sample kit first which was very helpful. I first ordered 100 pounds of blue glass and a couple hours later called to cancel the order because we decided to change out all the fabric on outdoor furniture. Steven, the sales rep, was very chill and refunded my credit card immediately. A couple weeks later, we decided on the amber color and Steven helped me place that order too. All together an easy process and a beautiful product.
