Certificate of authenticity for authentic Yixing teapot
To protect your rights and those of Siyutao's artists and craftsmen. We started using a set of certificates of authenticity on 03/21/2026.
Each Certificate of Authenticity features an encrypted password, a unique serial number, and a QR code. It is personally signed by the artist or the craftsman and bears the official seal of the Siyutao art gallery.
Its production uses special paper, ink, and multiple anti-counterfeiting hidden marks. Additionally, the certificate includes a photo of the teapot and its details.
It consists of two parts,
part 1 is a card with teapot information, including the teapot artist/craftsman, the date when the teapot was handmade, a clear photo of the authentic yixing clay used in this teapot (you can see it clearly after scanning the QR code), the unique identity code of each teapot, the teapot origin information, the teapot's mark and a clear indication that the teapot was produced in Dingshu Town, Yixing.
Part 2 is a collection certificate with the official seal of Siyutao Art Gallery. Not only that, each certificate has a photo of the corresponding teapot, an anti-counterfeiting code, and the signature of the artist/craftsman.
