These lava rocks will instantly give any old fireplace an exotic, yet classy look.

Naturally occurring, these lava rocks are formed as volcanic magma rises to the surface, cools and releases gases which gives these rocks their coarse surface. Because they are volcanic, they can withstand extremely high temperatures without sustaining any damage or crumbling.

Lava rocks may be used exclusively in a fireplace or fire pit, or may be used as a base or filler for other ornaments such as fire glass or lite stones. Whichever way they are used, the resulting effect is truly fascinating. The best part is that they require very little maintenance!

Available in various sizes!

PLEASE NOTE: The lava rock will vary in color from brown to black, this is normal.

Because lava rock is economical, it is the perfect choice as the first filler that goes into your fire feature to cover up the gas piping and tubes. Once the lava rock is spread the way you want it, add a layer of fire glass to create a truly spectacular look that will instantly become the focal point of your home.

How Much Do I Need?

The rule of thumb here is that, lava rock gives you twice the volume per pound as fire glass. So if you fire pit requires 40 lbs of fire glass to fill it, it will only require 20 lbs of lava rock. This is why small lava rock is a great material to use as a filler under your fire glass or larger Lava Stones, and therefore is easier on the budget. These lava rocks are in units of 10 lbs.

“Fire Pit Wind Guard. Adds elegant look to our firepit. Looks nice and adds a nicer touch to our firepit. It didn't come with any instructions, so I just had to figure it out by looking at the photo on the box. It isn't a perfect fit for our firepit, even though I measured, but it works ok so I'll keep it.”

“ Rectangular Fire Pit Wind Guard. It looks great. Feels solid. Thanks for the rubber feet. Do wish you had glued the tiny cushions to the tightening screws -- it was a little unhandy when I had to remove them and then set them all back in place before I could insert the glass. No biggie, just a customer satisfaction nit.”

“Fire Pit Glass Wind Guard. This is absolutely fantastic. Stops the flames from lying sideways in the wind, creates amazing reflections and making flames 4 times more visual from the reflections, glass radiates heat outward. Best experience improvement in a long time.”

“Rectangular Gas Fire Pit Drop In Tray and Burner. Great burner set up. This burner works really well and is a great set up for the $. I got quotes for similar burners costing 3-5x as much. I filled the tray and around it with lava rock and put gas logs on top. My fire pit looks so natural that at first glance people think it’s a real wood fire ”

“The fire glass was better than you can imagine! ”

“We built a custom outdoor "fire table" this summer and after installing a 48x6 burner it soon became apparent that we would also need a wind guard. With the flames down low any breeze would blow them over the side of the pan and cause soot marks. A higher flame and higher wind made 'downwind' diners wish they didn't have a beard! I was concerned with how well glass would survive shipment, when our package arrived there was no need for any concern. The wind guard is shipped ready for assembly and EXTREMELY well packaged. It comes in a custom built wooden shipping box with internal foam packing and small cork pieces to keep everything safe, secure, and well separated. Once unpacked it took all of five minutes to assemble, screwdriver is the only tool needed. We are very satisfied with the wind guard for our linear burner ”

“Beautiful custom Fire Pit, that's just my style. The drop in fire pit kit allowed me to custom design my fire pit to reflect my style. The spark ignition is like magic, all I have to do in push the button and the fire appears. There's no need for a hand held lighter or matches. I must thank The Magic of Fire for a speedy delivery. I made the deadline, yeah! ”
