Very nice indeed. And you are right, as long as it preforms the way you want it to, then that's all that maters.

Ciao for now.

Just by looking at the two products, the refractory cememt looked like it contained more silica.

I completed the project in mid May, and have used it almost every weekend (sometimes Saturday and Sunday) and a few weekdays. I am very happy with the results. The oven takes about 3 hours to bring to cooking temp and I can 7 or 8 pizzas (one at a time since it's a relatively small oven - 27 inch inside diameter) before I see a noticable cooling of the oven. This means that it takes a couple minutes more to cook the 8th through 12th pizzas.

Visual inspection of the inside of the dome shows no slumping or cracking of the mortar. BUT, ask again in 2 years and we'll see how it lasts! So far I am happy with the product, and the price was very reasonable.

One unrelated suggestion would be to buy a tile saw and a cheap grinder with a masonry blade. I didn't have the grinder until the dome was completed, and I realized (too late) that I could have easily beveled the bricks to fit together better, using less mortar.

I hope this helps!

Hey Anthony, how's that oven holding up? I am getting ready to cast my oven with FireRock and wanted to see if you had any issues with it. ANy suggestions, tips for FireRock would be more then welcome.
