Look at the bottom of a flowerpot engraved with China Yixing and a four-square paragraph has a collector's value

There are several factors to consider to determine whether a flowerpot has a collector's value, such as age, material, craftsmanship, brand, and keeping intact. Regarding Yixing ceramics, Yixing is one of China's famous ceramics producing regions, known for its unique production process and outstanding quality. As a representative of traditional Chinese craftsmanship, Yixing ceramics have a certain collector's value, especially signed masterpieces or those with a long and rare history. As for the four-square mark, if it refers to the pattern or mark on the bottom of the flowerpot that is in the shape of a four-square, it may not be the main collector's value factor on its own, but rather, it needs to be considered in conjunction with other factors such as the overall aesthetic value of the piece, the author, and so on. If you think this flowerpot has a collector's value, it is recommended that you consult a professional art appraiser, antique expert or ceramic collection agency for a professional appraisal and assessment. They can give a more accurate assessment and advice under comprehensive consideration through on-site observation, study of relevant information and market value.
