Thesis
“凡炙茶慎勿于风烬间炙熛焰如钻使炎凉不均持以逼” still has operational value at a contemporary tea table, provided Tang conditions are not silently universalised.
Text
“When roasting the tea, beware of roasting over a windy ash-fire, where leaping flames make the heat uneven. Hold it near the fire and turn it again and again, until bumps rise like toad-backs, then move it five inches from the fire.”
Context
炙茶:烤茶饼。风烬:有风的灰烬。熛焰(biāo yàn):飞腾的火焰。培塿(péi lǒu):小土丘。蟆背:蟾蜍背。
Evidence
- Collation: 各本一致。吴觉农注:炙茶为唐代煮茶前置工序,烤出"蟆背"即火候恰好。
- Existing readings: 吴觉农指出"炙茶"是唐代特有工序:饼茶须先烤软、再碾末,烤至"蟆背"出香而不焦——此"文火慢烤"之法,与今人醒茶、焙香异曲同工。
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.
