Subject:Re: Chinese blanc de chine Guanyin seal mark
Posted By: Bill H Wed, Dec 19, 2018
The square seal is one of the marks used by early 17th century Dehua potter He Chaozong (何朝宗) and reads down and across from the right (shown here in standard script) as "Seal of He Chao Zong" (He yin Chao Zong - 何印朝宗). The double-gourd seal above it reads down as "Dehua" (德化). Both of these seals have been imitated in modern times, which judging from the apparent lack of any signs of age, probably is the case with your Guanyin image.
