A backyard wood-fired oven built in high-quality firebrick and refractory mortar, from the oven body through the chimney.
I couldn't be more happier with my outdoor firewood oven… They used high-quality firebrick and refractory mortar, and paid close attention to every detail — from the oven to the chimney. It heats evenly, retains heat for more than a day.
