    Glass is very vivid and pretty. Looks great when you light a fire and see all the reflections. Seems like good quality it has been in my pit for a few months and hasn’t changed colors or anything.

    I first ordered this glass and then because of the low price, I expected low quality. Not true. The glass is clean, shiny and just as advertised. I paid 3x the price at another place expecting it to be so much better and it wasn't. It's not always true- you get what you pay for.

    These made my fireplace beautiful! The size of the glass rocks are perfect. Not too small. They function as they are supposed to and are durable.

    Took 5 of these 10 pound bags to fill my 31” fire pit. Wearing gloves is a good idea because there is a little bit of shards here and there and I used the glove to spread the glass around in my pit. It’s a very pretty blue!

    Reviewed in the United States on April 12, 2024
    This was a super easy project and changed the front of our room dramatically. After years of burning wood and dealing with the hassle and the mess, we finally stopped doing fires altogether and just had this useless, ugly, dated focal point in the room we spend 90% of our time in. The glass looks great and while the heat doesn’t match that of burning actual wood, we live in SoCal and don’t need the heat. That being said, when you’re sitting close to it, it will definitely warm you up. But now having a fire year round will make sense as it’s decorative more than it is functional.

    Probably did more research and overthought this more than was necessary, but I’m not a fire or gas guy and aside from splitting wood and making a fire, this seemed outside my wheelhouse. But it wasn’t!

    I did replace the burner, flex line, and all the fittings just so it would all be new. We lightly sanded, scrubbed and painted the inside all black. One thing I’d do different is I thought the biggest burner that would fit would give us the best flame and it probably does. But it’s so big that it can’t be centered because of the gas stub on the left side. I’d probably do a 16” or 14” burner instead of 18” if I had to do it all over again.

    What I found with my overkill research is there’s a lot of conflicting information on the best way to do fire glass. The fire glass sellers (of course) want you to fill the entire thing with fireglass but that’s not what I did. And some say to use lava rock as a filler while the manufacturers caution against it due to air pockets can trap glass between the rocks. Ok, I get that. And there is disagreement about whether or not sand should be used and even disagreement about whether or not the burner holes should face up or down. I really don’t think it matters but I wanted to disperse the flame over the largest possible area. And there’s even disagreement on whether or not spray paint or brush paint should be used.

    So here was my set up and why…
    Removed the glass and curtains (YouTube), burner pan, burner, flex line, fittings and tags/labels. Everytning…

    Taped and tarped and we opted to paint the frame as well so it all matches. And I did go with spray paint as I didn’t want to risk any brushed paint bleeding through the tape that wasn’t adhering all that great to the stacked stone. Ended up doing two light coats and that did the whole thing. I didn’t paint the bottom because I didn’t want to run out of paint.

    I did install the h burner inverted thinking the flame would disperse over a wider area and so the sand wouldn’t get stuck in the holes. Plenty of others though position their burner with the holes up and seems to work just fine as well.

    I then covered the burner with coarse silica sand so the flames would go up through the sand and disperse over a wider area. I can’t comment if it disperses better than if I woulda used all glass but I can say that the flame certainly disperses over a wider area than it ever did with lava rock.

    And I did reuse some of my old lava rock, the smallest pieces and used it as a base around the perimeter careful to keep it away from the burner. So…sand in the middle covering the entire burner and about 1/2” above it, and then about a layer and a half of lava rock around the perimeter.

    Covered the entire thing with one bag of this glass but I ordered a second bag as there is a tiny amount of lava rock still showing. Wearing gloves is recommended but since the glass is delivered in 3 separate bags, I had to mix it all up so I stirred it all up in a big bowl with a spoon, and the big spoon seemed like a good way to spread out the glass and then level it out so I got to skip the gloves part.

    In total it took about two hours, including the amount of time for the paint to dry. We’re super happy with it, it does put out some heat if someone wants to sit by it, and I would encourage anyone in a warm climate to try this if they’re looking to spruce up their old and outdated fireplace.
