  • Ancient iron production - Wikipedia

    Slag should also maintain its correct composition so that it can collect more impurities and be immiscible in the melt. Through chemical and mineralogical analysis of slag, factors such as the identity of the smelted metal, the types of ore used and technical parameters such as working temperature, gas atmosphere and slag viscosity can be learned.

  • The Chemical Composition of Stars and the Universe

    The chemical composition of the stars In the early days of astrophysics, scientists thought that the stars were probably similar to the Earth in chemical composition. When they passed starlight through a prism and examined the resulting spectrum, they found absorption (and occasionally emission) lines of many elements common here on Earth.
