When you build a fire pit do you need to use a special mortar? What premix mortar is best? How thick should it be mixed?

I utilize fire rings from Cunningham Gas Products. On firebowls I use the 6" and on firepits I use the 18" or larger depending on the size of the firepit. If your placing the firebowl on top of a pool beam you must use a sleeve through the gunite and then run a copper tube through the sleeve. Noble Tile has some fire bowls that range from very affordable to very expensive. Try Googling Noble swimming pool tile for their website. I would definitely suggest using a plumber to make your gas installation on either of these features. This is a job for Pro's, many people have no idea of just how volatile Natural Gas is.

We did consider a blue to go with our pool tile and might have gone that route if the granite had any blue or the right greys in it. I found the fire pit online but had to order through a dealer. The guy there showed us the stock glass, but also larger pieces. Some are larger crumbles and others look like small ice cubes or gems. I think he called one of them liquid ice -- the name because of how it reflects the light and looks melted from the fire. He said some people us one color for most of the glass and then scatter some of a different color on top or use some clear or colored larger pieces to catch the light on top. If I recall correctly, our pit has a dish that is about 24 inches wide and not too deep. The glass just covers the burner and I think we needed 80 lbs of glass. The glass runs several dollars a pound, so it is easy enough to change out, but it may not be cheap -- especially if your contractor is building a large brick pit. I assume he will insert a pan for the burner and make it more shallow? You may want to ask about that.

Does anyone know what these spots are on our fire pit and how I can remove them? It is a propane fire pit and we always keep it covered when raining (actually we keep it covered whenever it’s not in use). I also have it so the cover it tented that way water doesn’t pool. I tried to clean it with a sponge but it did nothing. You can see in one photo a long scratch from my nail so I think it must be able to come off somehow? I don’t want to scrub it too hard though and the scrubby on our sponge did not work.
