Factory One Shui Ping | 70cc | Hei Tie Sha | 1990 (Geng Wu Year)
Unused | Compact & PreciseA petite 70cc standard Shui Ping teapot made by the Yixing Factory One in 1990, marked “Made in Yixing Geng Wu Year (宜興庚午年製)” on the base.
The clay is Hei Tie Sha (Black Iron Sand), a high-iron purple clay known for its deep brown-to-charcoal tone and fine mineral speckling. Compared to standard Zi Ni, Hei Tie Sha is slightly denser and more mineral-driven in character, offering stable heat retention and a grounding effect on tea liquor.
In brewing, this clay tends to:
• Suppress overly sharp high notes
• Increase body and depth
• Enhance aftertaste and sweetness
• Produce a calmer, more structured cupIt performs particularly well with:
• Medium to heavy roasted oolongs (Wuyi Yancha, aged Dong Ding)
• Old Bush Shui Xian
• Shou Pu’er
• Aged white tea
• Traditional black teasThe small 70cc capacity makes it ideal for solo sessions or focused gongfu brewing, especially when working with high-aroma or high-intensity teas that benefit from tighter leaf-to-water ratios.
This teapot remains unused, preserving its original factory condition. A compact yet powerful brewing tool from a respected production era.
