This mug utilizes a proprietary technique that fuses porcelain and pottery. Artisans meticulously hand-apply a specially formulated slip onto the porcelain base using a brush before the initial high-temperature firing. Following this, they apply unique pigments that shift color depending on the angle of light and perform a second firing to achieve a mesmerizing finish. Every brushstroke is executed by hand, ensuring that no two pieces are identical. You will enjoy the distinct, artisanal texture and one-of-a-kind character inherent in this manual process. Master craftsmen at the Densakugama kiln-located in Arita, Saga Prefecture, the birthplace of Japanese porcelain-handcraft each item with exceptional precision. - Proprietary fusion of porcelain and pottery creates a durable yet artistic base - Color-shifting pigments provide a dynamic, iridescent visual experience - Hand-brushed textures ensure your mug is a unique work of art - Authentic Arita ware handcrafted by expert artisans at Densakugama
