Especially when building a larger oven, there are some clear earth oven building errors to avoid. (Building an oven is simple, but the truth is that nothing is quite as simple as it may first appear, especially when you build a fire in it.) Heather Coiner of Hat Creek Farm in Virginia (in photo) has generously documented some of the mistakes they made on a commercial-scale oven they built (and used successfully) on their farm -- and which they recently took down after building their next oven -- a full-scale brick oven built by Eric Moshier, of Solid Rock Masonry. Here's the link. It bears . . .
Thanks to muddy friends Ian Miller, Christo Markham, and Xavier Rodriguez, there are now German and Spanish editions of Build Your Own Earth Oven. The German edition is published by Stocker Verlag, (click here). The Spanish edition is published by EcoHabitar (click here). A few words of thanks are in order: Ian's first oven inspired him to start a bread business and build his own natural house; when his (Austrian) wife Andrea got accepted for an educational program in her homeland, he wrote me out of the blue, proposing an oven book for a German speaking audience. He took on the project, . . .
I've been experimenting with cheap ways to improve lo-cost wood-fired earthen ovens. How can I make mud denser, harder, and more durable? Without going to bricks and/or spending a lotta dough? Adding sand to mud reduces shrink and increases density. But clay and sand are generally still less dense (hold less heat) than a good, hi-fired dense firebrick. Hmmm... Experimental Goals: 1. to increase the density and toughness of a clay/sand thermal mix appropriate for building wood-fired ovens (and other wood-fired appliances?), 2. to fabricate a higher quality cast dome ("earth-oven") . . .
