針對「曾侯乙編鐘（以下簡稱曾鐘）全是用複合陶範鑄作，並且迄今尚末發現先秦時期失蠟鑄鐘的實例。」之說法，筆者通過如下幾方面分析，認為不妥之點有三：（一）全部曾鐘都是採用熔模法複製。實踐與陶範鑄鐘理論相悖。（二）鐘上遍布的變體龍紋凸出的尾部大都具有倒鉤的特點，顯然，這種倒撥模花紋分範用範盒是無法翻製的。（三）泥範在脫水過程中收縮變形率較大，針對一般認為由一百多塊範、芯組合的鑄型，裝配精度達不到曾鐘的實際要求。只要熔模鑄造才是當時生產曾鐘的實際方法。要除去彈性模具，必須使用金屬模料。筆者認為曾鐘是用泥範鑄模、用金屬鉛為主要熔模料的綜合型易熔金屬熔模法生產出來的。簡稱「漏鉛法」。

　　　　　This essay is written in response to the following opinion: "The bronze bells from the tomb of Marquis I of Tseng were made cast using the piece-mold process, and we have yet to discover concrete evidence of the use of the lost wax method to cast bronze bells prior to the Ch'in dynasty. " I would like to show that these beliefs are flawed, with the following analysis: (1) All of the Tseng bells were, in fact, reproduced using melt-away models, as opposed to the piece-mold process. The facts, then, do not coincide with the accepted wisdom. (2) The inverted, hooked tail of the dragon motif, carved in relief, that covers the surface of the bells could clearly not have been achieved using the piece-mold process. It features prominent melt-away model casting characteristics. The reproduction of the Tseng bells, utilized flexible silicone rubber models. (3) Clay naturally shrinks at it dries out during the firing process, and if the model was composed of over 100 separate parts, as suggested by some, it is inconceivable that the quality of the Tseng bells could ever have been achieved. In summary, the melt-away model casting method was the only practical way that the bronze bells could have been made at the time. Expelling a flexible model requires metal material. Accordingly, I believe that models for the Tseng bells were produced from lead, and that their casting process should thus be termed the "lost-lead process."
