Thesis

Section 6 is not really about “承一曰台一曰砧以石为之不然以槐桑木半埋地中遣”; it is about how Lu Yu turns tea from a local product into an object of argument.

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

Formally, the section gives a judgment, adds material detail, then returns to human practice. 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。 That is why the Classic of Tea reads as an argued book rather than a miscellany.

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.

Source: The Classic of Tea, Chapter II · The Implements, section 6; the original is in the public domain.

Modern tea science would split the sentence into cultivar, soil, light and plucking variables. 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。 The variables remain useful, but none of them alone explains the cup.

Storage adds another variable: moisture and temperature. 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。 Old and young tea do not share one shelf life, so “the older the better” is not a rule.

As a new reader, I first took “承一曰台一曰砧以石为之不然以槐桑木半埋地中遣” as a conclusion. Reading the annotation to section 6 again, it is clearly a judgment with conditions attached.
