The Scientific American 9, 27.8.1864
Res sealing wax of good quality is made by carefully fusing a mixture of 48 parts of shellac, 19 of Venice turpentine, and one of Peru balsam, to which 32 parts of finely levigated cinnabar and some sulphate of lime are afterwards added. In the cheaper kinds red lead is substituted for the vermilion, and there is much common rosin, which causes the wax to run int othis drops when melted. Black sealing wax is made of 60 parts of shellac, 10 of Venice turpentine, and 8 of finely levigated ivory-black.
