“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.”
