When calcined amorphous mineral silicate is added to traditional silicate stucco a shell can be constructed in 4 to 6 hours. Non-ferrous metal shells can be constructed in as few as 4 hours, whereas ferrous metal shells require 6 hours. The amorphous mineral silicate functions as a microscopic sponge that wicks moisture away from the damp slurry coat. After a short drying time (20 – 60 min), part of the stucco layer, which contains water-saturated amorphous mineral silicate, is mechanically removed (blown off). Approximately 75% of the stucco coat remains on the slurry coat after the mechanical removal. Slurry and stucco coats are applied until the desired shell thickness is achieved. After the seal coat is applied and allowed to dry ~ 1 hour, the wax is removed from the finished shell in an autoclave or by flash firing. Shells utilizing this process demonstrate easier shell removal and produce a finished product that has comparable results to current industry standards.
