Fired at a temperature of 1000°C, Karatsu stoneware is covered in a thick, dark brown or black glaze or a cracked white glaze with floral motifs. The famous three-chamber kiln of Nakazato Taroemon has been in operation for 14 generations and is still used once a month for about two days. The gallery-museum exhibits some of the oldest pieces of Korean influence and other more recent work (Taroemon). The fine art work and cracked enamel finish are highly prized by wealthy collectors of tea services.
