Ovens made by Fontana use about one-fifth as much wood as a traditional wood-burning ceramic oven, so they also produce much less smoke. Fontana Forni design ovens to burn hot and bright with a minimal amount of smoke. Our ovens also heat up much faster than a traditional masonry oven. Our oven preheats in 20-30 minutes (depending on the size) versus a 2-3 hour preheat time for a traditional masonry pizza oven. The reduced burning time with our oven reduces and further minimizes the output of smoke. The fuel efficiency and reduced smoke output of a Fontana makes it an environmentally responsible choice.
