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
Ceramic petrography in the prehistoric Aegean. In the USA the approach is less popular, though important contributions have been made in the area of quantitative petrography. Other attempts to extend ceramic petrography include the use of automated image analysis, the palaeontological analysis of microscopic fossils within ceramic thin sections and the combined statistical classification of petrographic and chemical data from artefacts. Thin section archaeological petrography can be applied to a range of other artefact types in addition to ceramics; these include plaster, mortar, mudbricks and lithic implements. Academic papers on ceramic petrography are often published in journals such as Archaeometry, Journal of
