How to tell that a yixing Clay teapot is authentic Complete Guide

Step into the world of tea, and you’ll quickly notice Yixing clay teapots hold a legendary status among enthusiasts. Origintating from Yixing, a city in Jiangsu Province, China, these teapots have captivated tea lovers for centuries. Why? The secret lies in the unique clay—known as Zisha—which means “purple sand.” This rare material possesses a porous nature, allowing the teapot to absorb the essence of the teas brewed within. Over time, the teapot develops a patina, enhancing the flavor profile of every subsequent brew. Some history: Yixing teapots go as far back as Song Dynasty (960–1279 AD) but it was in the Ming Dynasty when loose-leaf tea started to become popular that Yixing potters started making pots that were not only efficient at brewing loose leaf tea but also artworks with different shapes, glazes used, and carved decoration–each telling their own story. A common saying often quoted by collectors is: “in Yixing, a teapot is not just a teapot, it’s a lifelong companion”.

Aroma and Patina: Over time, you’ll notice that real Yixing clay creates a subtle earthy aroma an a matte, glossy patina.

A fake reflects an overglossy shine or one that is entirely dull.

Contact and behold the bottom of your teapot. Real Yixing clay teapots contain a seal typically etched or impressed on the underside of the teapot. Potential locations are on the body and inside the lid, often with artist-specific seals or stamps left behind by a creator.

Pour boiling water into the teapot, swirl it, and pour water out. A real Yixing clay teapot should exude a subtly earthen scent.

A real teapot will brew teas with a uniquely silky mouthfeel and over time, develop a soft, vibrant sheen. This sheen isn’t painted or polished. It’s achieved from tea oils seeping into the porous clay. Patina Over Time

The older a teapot is, the more clues it gives.
