What are these rocks made of that help prevent grass burn marks?

What I understand is that they act as a filter to draw nitrates and nitrites out of the drinking water. When these nitrates and nitrites (impurities) are taken into the body they increase the nitrogen in the urine. The excess nitrogen in the urine is the main ingredient that burns the lawn. A small reduction in the nitrate and nitrite intake reduces the nitrogen concentration output reducing the damage or burning to the grass. Nitrogen is used in lawn fertilizers (it greens it up) but when it gets to concentrated it burns and kills the grass.

the website addresses this. theyndo work, you must change them as recommended or the burns will start again.

i don't know what's supposed to be in them, but what ever it was, it must have been missing in mine. They didn't work. i went back to my original item of grass saver liquid

I have no clue, best to contact manufacturer. They work like a charm, my dog and cat have no issue with the rocks in the bucket they share outside, and the dog bowl inside.

They are made of a polybicarbonate and are tinted. So they provide shade but I can still see our trees through them. They also have a protective UV coating on the side that faces the sun.

I am unable to answer your question without further information. I tried to find out the true agreed definition for landscaped rocks but apparently there is not a decided up on size for the rocks. You know the weight of each of the rocks, correct? Are they the size of gravel and approximate weight of gravel? If so than your rocks will remain intact on either speed. I hope this is helpful.

It does come with a bag of black glass rock that is enough. But I wanted to spruce mine up, so I got; Fire Pit Glass Rocks, COBALT BLUE~3/8-1/2", 4 LBS Sold by: MailOrderRocksand used mixed the colors. I used about 2 lbs of the blue rock and took out half the black.

I believe it is the black clothlike material that landscapers use. You buy it at Home Depot, Lowes, etc. You lay it down and then cover it over with soil as a kind of base.

I'm pretty sure there is no paint in existence that will keep a rock from breaking glass. Shatter proof glass goes through a complex tempering process.

Not real sure of their makeup. The tires are a hard compound that have stood up to a couple years of rounds through the desert of Arizona. Lots of rocks and thorns have tried to ruin them but they have held up well.

I have built a "pit" with retaining wall stones from lowes four high. The ring sits atop the stones. The stones keep the fire safe and manageable, the ring is on top for looks and to keep taller wood contained. Look at lowes and you will be able to get an idea of how it functions.

I did not try it, i prefer the glass pebbles. You can purchase lava rock from any home depot/loews store.You should find them in the outdoor grills section.If you are thinks real rocks (river rocks..) i would just arrange them so as to get good gas flow distribution.You can get river rocks/peebles from any lawn and garden outlet.

I think it is charcoal stone- they call it a diffusion stone. It is the gray tip on the end of the tubing.

Sorry, I don't know. We switched to ceramic rocks and they look much better than the lava rocks.

It did not have grass seeds in the mesh and we have had great luck leaving the mesh in place as grass grows through it. It will disintegrate over time and is a easy way to stop erosion.

These ceramic discs are designed to replace the lava rock normally used in a charbroiler. They go in between the burners and the cooking surface, but these char diamonds are really only designed for charbroiler grills that allow spacing for these discs, by design.The main difference from lavarock is that lavarock absorb and retain grease where these ceramic discs do not.The discs shrink over time, so you'll have to add new ones from time to time as necessary. Also, as needed, let the grill run for a while after cooking to burn off any grease that builds up on them. They should be nice and white.

I have one of those grass themed drying racks for bottles and such and I hang my shields on the tree that goes with the rack. That way you can avoid getting water spots.

I live in AZ also and my grass is also surrounded by small rocks. My dogs sometimes kick rocks in the grass and I try to remove them before I mow. But the mower is pretty sturdy and mine hasn't been hurt by the small rock. This mower is perfect for a small yard, I love it.

Stone. Any kind of stone I used it for paver and retaining wall. What a great thing
