The blue hues resulting from yohen (kiln transformation) are exceptionally rare, appearing only when various conditions align during the firing process in a noborigama (climbing kiln). This is a guinomi sake cup crafted by Takashi Baba in Bizen City, Okayama Prefecture.
This product would be a great fit for those seeking an authentic, high-quality Japanese sake cup that showcases Bizenware pottery craftsmanship.
