The Green Plisse Medium Vase is attractive in a lovely hue of olive green. The deep furrows that that swirl around the bulge in its form tighten and straighten as they flow to the top and to the bottom in a uniformity that can only be machine-made. The most surprising thing about this handsome vessel is that it is made of 3D-printed porcelain, an ancient material you might not expect to be so amenable to such a contemporary process.
