overglaze painting; overglaze enamelling
Art term for applying decorative painting or enamel onto already glazed ceramics, then firing again at a lower temperature.
The overglaze painting on this plate is very delicate.
I tried overglaze painting at a pottery class.
Glaze itself; 上絵付け uses special overglaze enamels on top of the fired glaze.
Compound of 上 (うわ, 'upper, over') + 絵付け (えつけ, 'painting, decoration'). The term refers specifically to decoration applied on top of the glaze.
