Mr. Fireglass Lava Rock Granules, Large Black Volcanic Lava Rock for Fire Bowls, Fire Pits, Gas Log Sets, Indoor or Outdoor Fireplaces - 10 Pounds (2.75"-5")

Used this rock for my outside gas fireplace.

These are super large, and they look great in our fire pit. No popping, and they seem like they will last a very long time.

Good stuff! Exactly what I was looking for.A bit dusty, do not open indoors.

The fire pit was well packed and everything was in good shape upon opening the box. It was fairly easy to put together but you'll want to be careful with the table top when turning it upside down to tighten the screws as it will scratch easily - it doesn't matter much though as it's a fairly 'rustic' looking table. Be sure to remember to leave the screws slightly loose until you have all of them in place or you might have trouble fitting a screw or two. I replaced the blue glass beads with small red lava rock as the blue glass doesn't really go very well with the style of the fire pit. When installing the propane tank I removed the locking screw as it's very awkward to use with the tank installed -the tank is heavy enough to stay in place on it's own though. We have used the pit quite a few times now and have found it doesn't light very well, it seems like the gas doesn't initially flow well, perhaps because of the cold, I don't know. I made sure the spark area is clear per the instructions and hold the control knob in until the flame takes hold. If used frequently it's easier to light, if left for a few days it's harder to light. I bought a lighter from the grocery store which seems to be easier to use. Despite the trouble with lighting it I would recommend this fire pit and would buy it again. Only four stars though because of the trouble with lighting the fire pit.

I love this product it did exactly what it was meant for. It looks classy and burns well. The quality is good and is affordable.

At first I was thinking that 10lb wasn't going to be enough for my natural gas fireplace but I was completely wrong. It was more then enough and looks perfect w the logs set. Couldn't be happier...

I have bought these a couple of times. They are not black. I would have returned, but I already dumped them with my black rocks.

Make sure you rinse this thoroughly before you put this into your aquarium. Will cloud up your water. Sizes are pretty good and looks nice.
