Thesis

“风炉以铜铁铸之如古鼎形” still has operational value at a contemporary tea table, provided Tang conditions are not silently universalised.

Text

“The wind stove is cast of copper or iron, shaped like an ancient tripod.”

Context

风炉：煮水用的炉子，仿古鼎形制，以铜铁铸造。

Evidence

• Collation: 各本一致。唯后世刊本或作"古鼎形"或作"古鼎之形"，无实质差异。
• Existing readings: 吴觉农指出：风炉取鼎形，既稳固聚火，又寓"以茶事承三代礼器"之意；陆羽为风炉铭刻"坎上巽下离于中"等卦辞，可见其以易理入茶器的审美。

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.

Water and fire magnify the difference. The same leaf at a higher temperature or a longer steep changes the sweet-bitter balance; the text only becomes operational at the brewing stage.

In Tang context, 吴觉农指出：风炉取鼎形，既稳固聚火，又寓"以茶事承三代礼器"之意；陆羽为风炉铭刻"坎上巽下离于中"等卦辞，可见其以易理入茶器的审美。. Tea was tribute, medicine and monastery drink at once, not a standalone commodity; the conclusion cannot be transferred without that context.

Modern tea science would split the sentence into cultivar, soil, light and plucking variables. 吴觉农指出：风炉取鼎形，既稳固聚火，又寓"以茶事承三代礼器"之意；陆羽为风炉铭刻"坎上巽下离于中"等卦辞，可见其以易理入茶器的审美。 The variables remain useful, but none of them alone explains the cup.
