The quantitative objective characterization of tarnish gave results which are identical with those obtained from a blind subjective analysis. 2. The low-gold alloys fall into three classes. The alloy Ney Cast III is superior in performance to the other low golds and approximately equivalent to the high-gold alloy Firmilay. The intermediate alloys, including Midacast, Stabilor G, Mowrey No. 46, Tiffany, and Midas are similar in performance to the high-gold alloy Rx O.R.Y. The low-gold alloys Dent Cast 44, Minigold, and Progold tarnish in a manner which, in our opinion, makes them unacceptable.

对变色进行的定量客观表征所得到的结果，与通过盲法主观分析获得的结果相同。2. 低金合金可分为三类。Ney Cast III合金在性能上优于其他低金合金，且大致相当于高金合金Firmilay。包括Midacast、Stabilor G、Mowrey No. 46、Tiffany和Midas在内的中等合金，其性能与高金合金Rx O.R.Y.相似。Dent Cast 44、Minigold和Progold等低金合金的变色方式，在我们看来使其无法接受。
