GASPRO 20LB Fire Glass Diamonds-1-Inch Caribbean Blue Reflective for Fireplace Fire Pit

Beautiful color, really stands out in my gas fireplace!

Purchased: 20# of the Caribbean BlueLook: They look great out of the bag. The color matched well with the photo. A review mentioned how they shimmer in the fire - 100% and it is mesmerizing and quite pretty. There was slight discoloration for the pieces right against the flames, but that's not a deal-breaker at the moment.Status: Two uses. One for 15 minutes and the second for about 90 minutes. I am using a custom table with an 80,000btu insert and a propane burner with an air mixer. I settled on leaving my regulator at half speed ~10psi (the flames were about 6" or so).Use: THESE WILL CRACK if high heat is immediately applied. On my first go, I was testing the insert and gas lines and shot straight to 10-15 psi. Cracking started immediately and about 2-5% broke. The cracks left sharp and jagged pieces that would be dangerous to touch, I noticed many 1 star reviews commenting on this and I agree. On my second go, I decided to gradually increase the heat over about 5-10 minutes. I think this protected the glass from the shock of instant cold to hot. I heard only a few light cracks and saw no additional breaking. Afterward, I left the burner on for 90 minutes, again at ~10 psi. I noticed no additional issues after this. I am curious if they will eventually temper, but I will update this review if that is the case or if anything else changes. I thankfully did not notice any melting which I saw in another review, but I will be sure to update if that happens.

This is a great product and does well in a fire table

Absolutely gorgeous! This fire pit came with lava rock, even after the break in period it shot hot lava rock at me and burned me pretty bad. I was going to just buy a cover then I ran across these. Sooo happy! They are gorgeous!

We put these in our fire table and they look very nice. The very first time we lit the table, one of the "rocks" shattered into a number of small shards. There was enough force that I found pieces a few feet away from the table. I'm glad no small children were standing near us when it happened, as that would have been near their upper body/facial area. As far as we know that was the only one, so I don't expect this is a widespread problem. I suppose others could have done this but they weren't near the top of the pile in the table. We've noticed no other issues with them since, but we've not used the table much either.
