This is a beautiful early 20th century bottle shaped vase with rounded body gradualy sloping to a slightly flared neck. It is done in wonderful and deep colored copper red and mirror black glaze. Sang Yang Kai Tai was first developed during the Yongzheng reign and continued during Qianlong period, though 18th century exmaples are rather rare. It is named in reference to the change of season from winter to spring, when darkness is dispersed by the sun.
Excellent condition with no damage or repairs. Crazing is normal for this glaze and seen in most if not all Republic examples. Some chips on inner foot rim as a result of the runny glaze being removed from the kiln at firing.
