Bizen was a little behind the field, only obtaining a unique process and
getting it off the ground at the beginning of the Muromachi Era (with only temperatures
of 1200°C, [2192°F], Bizen used
slow firing to realize hardnesses in excess of those at Tokoname, etc., with 125°C, 257°F). It
grew to obtain an 85% share of all pottery in the area around the capital, the
Japanese consumption region with the greatest economic activity at the time.
During the period of tea ceremony culture that followed, Bizen continued to
have a central status.
