Thesis
“承一曰台一曰砧以石为之不然以槐桑木半埋地中遣” still has operational value at a contemporary tea table, provided Tang conditions are not silently universalised.
Text
“The cheng base, also called tai or zhen, is made of stone; otherwise of locust or mulberry wood, half-buried in the ground so that it will not rock.”
Context
承:垫在规下的台座,又叫台、砧(zhēn)。用石制;或以槐木、桑木半埋入地,使其稳固不摇。
Evidence
- Collation: 各本一致。吴觉农注:"半埋地中"是为压实茶饼时台座稳固,唐代制茶作坊的朴拙智慧。
- Existing readings: 吴觉农指出"承"是压制茶饼的操作台,须稳如磐石;"槐、桑木"皆坚重之材,半埋入地以取稳——制茶之讲究,连台座也不放过。
Analysis
To repeat this section today is not to copy a Tang utensil list. It is to keep its order of judgment: leaf first, then water and fire, then the table.
Conclusion
The section does not give a universal rule. It demonstrates a method: read the text, the annotation and the Tang context together before making a modern claim.
