The Pinnacle of Zini: Why Dicaoqing is the Connoisseur’s Choice
If Zini is the soul of Yixing, then Dicaoqing (Premium Zini) is its most precious heart. Sourced exclusively from the deepest, most compressed layers of the legendary Huanglong Mountain mineral veins, Dicaoqing represents less than 8% of the total purple clay harvest. It is the definitive choice for the seasoned tea lover who demands the ultimate balance of rarity and performance.
Nature: The "Gold" Within the Trough
At DXY ZISHA, we don't settle for surface-level minerals. Our Dicaoqing is hand-selected from the deep-well troughs (Hole No. 4), ensuring a mineral purity that is becoming increasingly rare in the modern market:
- The "Ji Yan" Signature: The hallmark of authentic Dicaoqing is the presence of "Chicken Eyes"—tiny, greenish-gray glauconite spots embedded in the ore. In our finished teapots, these appear as subtle, golden star-like grains. This is nature’s own "Security Watermark," proving its deep-vein origin and raw, untreated pedigree.
- Elite Tea Interaction: Dicaoqing is the ultimate "Tea Tamer." Its specific mineral density and high iron content act as a catalyst for aged teas. It doesn't just round out bitterness; it actively "unlocks" the deep woody, camphor, and honey notes that cheaper clays often suppress.
- The Perfect Partner: Specifically engineered by nature for Aged Raw Puerh, Premium Oolongs (Yancha), and Aged Black Teas. It delivers a tea liquor that is exceptionally clear, vibrant, and packed with a lingering Hui Gan (sweet aftertaste).
The "Jade-Like" Evolution: A Patina of Distinction
Owning a DXY Dicaoqing vessel is an investment in a living heirloom. Because our clay undergoes a rigorous, years-long natural aging process (Chen Fu), it possesses a "Hidden Luster" that is purely organic.
This is a "Fast-Transforming" clay. With regular use, the matte, star-speckled surface begins to "Jade-ify"—developing a deep, lustrous patina that feels smooth and warm to the touch, like a piece of ancient jewelry polished by time. For the collector, the joy of seeing a Dicaoqing pot "awaken" is one of the greatest pleasures in the tea world.
DXY Scientific Benchmark & Integrity
Dicaoqing is defined by its natural 4%–5% porosity and high Silicate/Iron mineral ratio, providing the ideal stable micro-climate for tea leaf expansion.
The Commitment: 100% Deep-Well Original Ore | Visible "Ji Yan" Hallmark | No Chemical Additives.

Q: Why a Dicaoqing teapot exhibit a subtle greenish-grey undertone alongside the golden grains?
A: This multi-tonal aesthetic is a direct result of the natural mineral symbiosis in Dicaoqing ore. The deep-vein "green ore" particles and golden mica flakes are interwoven naturally, creating an organic profile. This contrasts with teapots that show a perfectly uniform, monochromatic color, which often indicates industrial mud-blending or chemical coloring.
Q: Why are there faint, "flocculent" or layered mineral patterns visible on the body of a Dicaoqing teapot?
A: These patterns are the physical legacy of the "sandwich" structure found in raw, deep-strata ore. By employing traditional stone-milling instead of high-speed machine pulverization, these original mineral layers are preserved. A finish that is entirely smooth and devoid of these organic flow-marks often suggests the use of machine-processed synthetic mud.
Q: Why does a Dicaoqing teapot appear translucent and "cyan-moist" when rinsed with hot water?
A: This "cyan-glow" thermal reaction is a specific property of bottom-layer Dicaoqing minerals. It responds to heat by becoming visually clear and vibrant, showcasing its unadulterated purity. This differs from the darkening or "muddy" reaction seen in clays where iron-based pigments have been added to artificially mimic a deep-layer appearance.
