FB Mortar
I am happy to say that we have made the product transition from Refmix to the new FB Mortar. FB Mortar is a true refractory, high temp, waterproof mortar that you can use to assemble modular pizza ovens, brick ovens and fireplaces. It has an additive that makes it sticky, which helps when assembling the Pompeii Oven. It is heat resistant to over 2000F, and unlike Portland cement-based mortar, it can withstand the heat cycle of a pizza oven without becoming brittle and breaking apart.

It comes dry in a 55lb bag and costs $50. That's a lot less then before.

You can order it through the FB Store, or by call us on (800) 407-5119.


Keep building.

Re: FB Mortar
Hi James,,,
Congratulations on your new product.... Have you considered making smaller bags for shipping in USPS flat rate boxes up tp 70 lbs..
for a 12 x 12 x 5 /12 box cost anywhere in USA is 13.95.... How many pounds could you fit in that box,, and would it be cost effective... I know shipping is what stops me from buying a lot of things off ebay...

Just a thought

Re: FB Mortar
James, I used Heat Stop primarily because of the cost of Refmix. I wanted to support Forno Bravo because I wouldn't have been able to build an oven without the support of the forum and the e-book, but the shipping cost of Refmix made it unaffordable. I called the Heat Stop manufacturer to ask for their distributor in Utah, and he called me back later and offered to sell it to me direct. He charged me a delivered price. I agreed not to post the price he charged me, so I'm trying to figure out how to let you know that your price is competitive without violating my agreement with him. Let's just say that I probably would have bought the FB mortar if I had been able to pick it up from FB, but the cost of shipping might still have flipped the decision the other way.

Re: FB Mortar
Hi Joe,

If you feel comfortable sending me a PM, I would not post it either. If you don't feel good about it, that's fine too.

We will be pouring FB Mortar into a plastic bag in the USPS box tomorrow and will find out how much it holds. :-)

Re: FB Mortar
James, I sent you a pm.

One option I would have considered was the kit. I wasn't aware of it until I was well into building my dome. I might have gone with that because the kit price is very good. Do you have an option for the floor to be brick? I know the big floor pieces are nice, but I really like the look of the herringbone floor. It's old school.
