Masonry oven modular ovens, all these methods are still in use. In all cases, the ovens typically go under a roof or some kind of weather protection. Perhaps the most significant change in masonry oven construction practices is insulation. Since masonry loses heat as fast (or faster) than it absorbs it, early ovens extended bake times by increasing mass. Thicker walls held more heat to bake more bread — but only up to a point. Since heat moves from high to lower temp, the outside of the oven can’t get as hot as the inside — unless you wrap it in a
Conservation and restoration of ceramic objects materials can be harmful to ceramic objects. Wool felt attracts and harbors insects including moths and silverfish which can be potentially very harmful to other collection material types. Polyurethane foam deteriorates over time which leaves a by-product that are sticky and acidic.
