Spherical with a bit of a bulge around the equator. Spiral hammer marks from centre of bottom. Mottled robin's egg blue. Around rim is irregularly darker(from initial bleach treatment of the cupric nitrate). Silver leaf interior, quite bright. The effect will be enhanced when the silver tarnishes a bit like old silver, to an iridescent lustre. The vessel is alive in the sense that it will change with time. The process will take years to decades.
Measures approximately 8 H D 9 W cm
