Another advantage of working with adobe is the relative speed in which house walls can be built, seven courses a day for walls 10" or 14" thick, and three courses high each day for walls 20"-28" thick during sunny hot weather.For strength and durability, as well as aesthetics, the adobe brick and mud plasters should have a low number of small shrinkage cracks, which often occur during drying.After about an hour, further gradation results with layers of fine silt and then clay at the top.By visual inspection one is able to estimate the relative proportions of clay to sand.Sometimes for the taller bases, this beginning phase should take two work sessions (for a longer drying period).Now the small dome of the oven can be started on the top of the platform hearth.A slurry of mud is placed in a form and left to set for awhile.
The standard sized adobe for building in New Mexico is 10" wide, 14" long, and 3.5" thick (the width of a wooden 2"x4" form).
This can vary in height from one to three feet, with the width of the oven being 2' to 6'.
Located away from ponding areas (standing water) with some drainage, stones or adobes are placed in mud mortar at ground level to begin the massive base.
By use of the form (approximately 4"x7"x 2.5"), each adobe will be the same size (with more complex angles if desired), which allows simple mortaring and assemblage for making the round shape.
This formed adobe would ideally be pie shaped (and truncated at the narrow end).
