Overview
A refined set of five Japanese ceramic sencha or tea cups featuring a striking Tetsu-kesho (iron-slip glaze) finish. The matte, cast-iron appearance is achieved through rich iron-oxide slips fired to create a dark, metallic sheen over a dense clay body. The exposed light foot rings contrast beautifully with the moody, satin-black iron surface.
Story
Centuries of Japanese tea culture prized ironware for its heat retention and earthy aesthetic. Master potters recreated that coveted metallic texture in clay using iron-rich liquid slip techniques. These bowls capture that rustic, tactile elegance in a modern form.
Maker / Origin
While unsigned, these pieces embody regional Japanese craft traditions such as Mino or Shigaraki ware. Studio workshops in these historic pottery centers specialize in balancing traditional glaze formulas with minimalist modern tableware designs.
