Textured with green drips overall, the gaiwan is stunning to be topped with large vitrified green glaze on the lid , and the bottom is pooled with green inside as well with dark drips surrounding the edge of the body , absolutely being a visual feast. Firing: Woodfiring 3 days and nights Inside glazed: YES Volume:120ml (up to the lid) Dimension:∅=9cm , H= 7.5cm Note: the appearance of gaiwan might be changed inside and outside with regular use because the tea residual may have an effect on it and cause the color change. It is a normal reaction and food safe as well.
