This kind of blue and white pattern is hand-drawn by skilled craftsmen with their own ideas so even the pattern is the same, the styles are different. The hollow engraving process is applied on thin embryo cups to make regular holes, which become translucent, crystal after glaze firing. The green and transparent holes and the hand-drawing China flower are complementary with a special aesthetic quality, presenting the highly technical and artistic achievements of ancient Chinese porcelain. The color of glaze is very glamorous and the hollowing engraving part doesn't make water leak. The specification is 7.2 cm in width, 3cm in height, 50ml in volume and 22.7g in weight.
