Hand-Painted Blue & White Underglaze Red Landscape Ya Shou Bei (Pressure Hand Tea Cup)

By artist Modu：this cup uses the underglaze blue and red technique, one of the rarest and most difficult crafts in Jingdezhen porcelain. Unlike standard underglaze blue, this technique uses two mineral pigments: cobalt for the blue mountains, trees and figures, and copper red for the vibrant maple leaves. The two pigments have extremely different firing temperature requirements—even a 5-degree difference in the kiln can ruin the red pigment, turning it black or burning it away entirely. For centuries, even imperial kilns struggled to produce perfect underglaze red pieces, making this craft a true test of an artisan’s skill. Every line of the misty mountains, every dot of red on the maple leaves, every detail of the scholar walking by the stream, is painted freehand with a fine brush, no stencils, no shortcuts. Fired at over 1300℃, the pigments fuse permanently with the clear glaze, so the colors will never fade, chip, or leach, safe for a lifetime of tea moments.
