    Re: NH Oven Build

    Two questions,
    How thick did you make the dome and did you use stainless steel needle reinforcing?
    Kindled with zeal and fired with passion.

      Dome was about 2" thick and I used polypropylene fibers in the mix.

        Good job. The polypropylene fibres give your refractory a measure of protection from blowing (rapid steam expansion), but they don't provide any additional reinforcing. I didn't use them in my first oven and it still fires ok. Interested to see how your dome performs over time.

          Thanks David. It has been a learning curve, thats for sure. But it has also been fun. Hopefully it holds up well, but if it doesn't I am not out a lot of money.

            Re: NH Oven Build

            Wednesday night I was in a panic. I was getting ready to cast the last big piece(oven opening), and I decided I should see if the other pieces would release from the form. I had used vegetable oil for a release agent, and the pieces did not want to release. After about an hour and some cursing, I finally was able to get them to release. Apparently, the form I made was of plaster. I sanded it down and painted a coat or two of Kilz primer on it. The cement acted like a suction on the primer. When it finally released it took the primer off with it. Luckily it peels off the inside of the oven like a skin. Anyway, today I took the day off from work to get some other projects finished around the house. When that was done, I cast the last pieces of the oven. I also picked up my stainless steel pieces for my flue and chimney. Good busy day today.

                Re: NH Oven Build-Update

                Well, this will be my third summer with the Homebrew castable refractory oven. We have cooked over 200 pizzas in it over the last 2 years. Few hairline cracks, but she is still running strong. Last Memorial Day we hosted our 1st annual Pizza Cookoff. We cooked 64 pizzas in 3.5 hours. It was a blast. This weekend we will be hosting the 2nd Annual Pizza Cookoff with 3 divisions: Traditional, Specialty and Dessert. Thinking about building one to start a mobile wood fired pizza business.

                      UPDATE- It has now been about 4 years and many, many firings. I am happy to report that the Homebrew castable refractory has held up awesome. Not showing any signs of crumbling or break down.
