Apparently it is a type of Wood's Metal and is a bismuth alloy : Roscoe & Schorlemmer, on "Metals" says Fusible Metals. Proportion of contents. | | Newton's Metal. | Roses Metal. | Lichtenbrg's Metal. | Wood's Metal. | Lipowitz. | |---|---|---|---|---|---| | Bismuth | 8 | 2 | 5 | 4 | 15 | | Lead | 5 | 1 | 3 | 2 | 8 | | Tin | 3 | 1 | 2 | 1 | 4 | | Cadimun | 0 | 0 | 0 | 1 | 3 | | Melting Point C | 94.5° | 93.75° | 91.6° | 71° | 60°. | "Fusible metal is now largely used for stereotyping, obtaining copies of wood-cuts etc. and is not only valuable on account of its low melting point, but because it expands considerably in the act of solidification and thus gives a perfect cast, it is important to make the cast when the metal is so far cooled that it is beginning to be viscid". We have completed the model of the mascot (¼ scale) in wax, and have made several test specimens Cont'd.{John DeLooze - Company Secretary} | ||
