Beautiful but small

This cup is a work of art. The color is soothing and the quality is top-notch. Just be aware it is quite small, intended for traditional tasting rather than large servings.

Perfect gift for tea lovers

Bought this as a gift for my father who loves Gongfu tea. He was thrilled with the Ru kiln style and the unique octagonal design. Packaging was secure and premium.

Exquisite craftsmanship

The sky blue glaze is even more beautiful in person. The octagonal shape feels comfortable in the hand, and the crackle pattern is subtle yet elegant. Perfect for my daily oolong sessions.

Nice but fragile

The aesthetic is undeniable, but the rim feels very delicate. I am always worried about chipping it when washing. Handle with extreme care.

Great for aging tea stains

I've been using this for a month now, and the 'cultivable' aspect is real. The tea soup is starting to leave a lovely patina on the inside, enhancing the vintage feel.

Authentic Ru Kiln vibe

As someone who collects tea ware, this piece stands out. The crackle lines are natural and the sky blue hue captures the essence of classic Ru porcelain without the museum price tag.

5 FAQ

Q: Does the crackle pattern change over time?

A: Yes, part of the charm of Ru kiln ware is that the crackle lines can absorb tea oils over long-term use, subtly changing color and deepening the vintage appearance.

Q: Is the octagonal shape difficult to hold?

A: Not at all. The eight sides are gently rounded to provide a secure and comfortable grip, often making it easier to hold than a perfectly smooth round cup when hands are wet.

Q: What is the exact capacity of this octagonal cup?

A: The cup holds approximately 50ml (1.7 oz) when filled to the brim, which is standard for a master cup used in traditional Gongfu tea ceremonies.

Q: Where is this product manufactured?

A: This Guanzhi master cup is crafted in Jingdezhen, China, known as the porcelain capital, using traditional firing techniques to achieve the authentic Ru kiln effect.

Q: Is this cup safe to use in a dishwasher?

A: We strongly recommend hand washing only. The high temperatures and harsh detergents in dishwashers can damage the delicate crackled glaze and affect the cultivable patina.
