Khmer ash-glazed tea bowl, 12th-16th century

This is a Khmer ash-glazed tea bowl (15th-16th century, excavated) with a quiet color. The color tone is also soft, reminiscent of egg-glazed tea bowls. It seems that it will develop a good flavor if used as a matcha bowl. The rim is slightly thin. I think it would also be nice to use it as a confectionery dish or for serving dishes.
