“What still vastly increases the fusibleness of these Metals is the addition of Bismuth or Tin-glass, a Marcafite or Sulphureo-metallic substance, not so easily melted as Tin. That Bismuth Sir Isaac Newton used in these curious experiments, we shall just now have occasion to copy from him, did not melt with a heat under gr. 460 ᵇ. And Dr. Musschenbroek’s Bismuth was much harder to dissolve, to wit at gr. 1051 ᶜ. And a golden Marcasite, though more fluxil, took gr. 506 to melt it.”
