GASPRO 10 lb Large Black Lava Rocks, 1-3 Inch, Ideal for Outdoor Fire Pits, Indoor Fireplaces with Propane and Natural Gas

These are fairly large and heavy rocks. Perfect for my paludarium setup!

These are perfect for terrariums and paludariums. Very light and porous stones, you get about 2 cubic feet worth of them. Good deal even compared to my local hardware stores and much larger pieces of stone

I bought a bag of these through Amazon & the rocks were perfect size without issues. We put it in our gas fire-pit outside and lite the fire. No problems. However, we needed more rocks to fill the pit. A week later I went into my orders to purchase from the same vendor. The rocks seemed a bit larger than the first bag we received but that is not an issue. However, we put these in the fire-pit and within 15 minutes we had a rock explode and pop out of the pit like bomb. We let it burn for a while thinking it may have just gotten wet somewhere down the road. Today we lite it again, same problem. It pops and cracks and spits projectiles out of the pit!!! Super unhappy, not sure how to return since they are all mixed together with the other rocks. My advice, do yourself a favor, buy from a reputable BBQ company and pay for shipping. Or your local store. These are dangerous!

Lots of them and in a variety of sizes. I got them for my vampire crab tank.

Lit up propane fire pit using my new lava rocks. I’ve only had the pit for a year, didn’t need new rocks til now and never had burn marks or crackling embers. I put in the new lava rocks and started the fire, then nearly “ran for the hills” after it immediately started popping loudly and I heard a piece of shooting rock ping against side of my camper. Happened 2-3 more times, lucky I didn’t get hit by flying debris, that would have smarted. Here’s a pic of 1 of 3 burn marks on my new indoor/outdoor rug (I’d already removed the small black ember that caused it). Not a big deal, but was just so surprised, this didn’t happen when we first lit it up on initial purchase. No more issues after the first night.

The product is great but the size is all wrong. It says 1-3 inch size rocks. All mine were 3 plus inches.

Purchased for making terrariums, and couldn't be happier. They look great and had a good mix of shapes and sizes.

I must say I was rather surprised by the size of these rocks. They are huge and fit the bill for my needs. I would highly recommend purchasing if you are looking for rocks of this size

I could not buy large rock like this anywhere in Australia so purchase them in USA.

Way more heat

DO NOT BUY THESE ROCKS EXPLODE!!!!! SUPER DANGEROUS.

This is one of the few labs rocks I've purchased that are actually BLACK instead of mostly red/ orange colour. I would of given 5 stats but I only got a couple pieces that were actually over 4 inches.
