Craft record

Notes from the bench

The bowl is raised from sixty-two individual iron plates, each hand-forged, riveted and filed until the seams read as a single curve. House Mizuno lacquers in the old Kaga manner: eight grounds of black urushi, each cured in a cedar chamber for nineteen days before the next is laid.

The maedate crest is not cast. It is a single sheet of copper, hammered over horn forms and fired with gold in the mercury-free kaga-mekki method the house has guarded since the seventeenth century. Under candlelight it does not glitter — it glows.

The silk lacing is dyed with fermented indigo to the depth called kachi-iro, "the color of victory," and will darken, not fade, as it ages.
