The blue on blue-and-white porcelain is painted under the glaze

For underglaze blue porcelain, a maker paints cobalt-blue designs on the pale ceramic surface. A transparent glaze covers the painting before firing and leaves the blue visible beneath a glossy finish.

One blue brush can put a bird, a branch, and an entire little landscape on a vase.
