Practice today is not much different, except that synthetic corundum a - AI2O3) has replaced the natural gems. Until about 30 years ago, nonspreading clock oils had been obtained mainly by various refining procedures from porpoise jaw, blackfish, olive, neat s-foot, and bone oils by procedures which were more or less considered as trade secrets. The principal difficulties with these products were their tendencies to evaporate, to thicken, and to deposit gums. Batches of oil from the same source were often too variable in nonspreading and stability... 

The contribution of bromophenols to seafood flavor and tainting has been clarified [58-59], It appears that bromophenols are natural components of seabed algae and other sea creatures (e.g., worms). They are considered to contribute to the characteristic desirable flavor of the seafood when at low levels. However, high levels of these bromophenols in the diet result in tainted product. Boyle et al. [59] found about 3 ppb was a normal bromophenol level in seafoods. However, levels as high as 38 ppb in herring, 30 ppb in salmon, and 100 ppb in shrimp have been fonnd. These levels would be expected to produce taints. Whitfield et al. [58] found 2,6-dibromophenol as the primary source of taint in prawn with 2- and 4-bromophenol, 2,4-dibromophenol, and 2,4,6-tribromophenol as secondary contributors. Whitfield et al. [60] identified various bromophenols as the source of an iodine-like taint in blackfish (Australian origin).
