Earthen ovens are inexpensive to build, fun to use, and provide a baking environment impossible to recreate in the kitchen. Attendees will leave the class with the knowledge necessary to build an oven of their own, with materials that you may already have in your yard. The class is suitable for bakers, building professionals and DIYers, and is a great introduction to adobe construction and earthen plasters covered in more depth in adobeisnotsoftware’s other classes.
