This is a large Chinese Yongzheng period (AD 1722 - 1735) minyao copper red glazed, sang de boeuf (ox blood) or Langyao porcelain bowl. It has a glossy glaze of crushed raspberry colour and white rim where the glaze thinned. It has a very well-balanced shape. The wall is thick. The characteristic square-shaped mark within a double circle in underglaze blue on the bottom shows that this bowl dates to the Kangxi period. Similar bowls produced at the imperial kilns are in large museums and collections around the world, such as the one in the prestigious Zhuyuetang Collection of monochromes of the Yuan to Qing periods of Hong Kong shown in the last photo. It is in pristine condition.
