【Pine Stump Cup 5】 Longshantang - All Handcrafted Biomorphism Series - No. 4 Deep Well Di Cao Qing - 150cc

【Local Taiwanese Store with Comprehensive After-Sales Service】 【No. 4 Deep Well Di Cao Qing】 Sourced from Yellow Dragon Mountain's No. 4 Deep Well Authentic Yixing Zisha Raw Ore. No. 4 Deep Well Di Cao Qing is located at the bottom of the ore layer. The raw ore features purplish clay with light greenish, eye-like speckled patches of Duan Ni. These "eyes" are distributed densely and evenly in pairs. Within the blocky texture, there are greenish "eyes" and "cat's eyes," indicating purplish clay containing Duan Ni particles. Due to the rich natural iron oxides present in No. 4 Deep Well Di Cao Qing, its color leans towards purple with a hint of green. The final fired color is contingent upon the ore's composition and firing temperature. The clay body displays fine, dense golden-yellow granules, appearing as scattered specks. Its purplish hue with a greenish undertone is exceptionally rare, and the clay itself is exquisitely fine. After firing, it develops a purplish-red color with a wide firing range. Commonly seen market pieces exhibiting a "pig liver" color are typically fired around 1200°C. The texture is firm, fine, and lustrous, with a shrinkage rate of approximately 10%. 【Frequently Asked Questions】 1. How to prepare the teapot before first use?
