Many of the metallurgical skills developed in the Bronze Age were still in use during Roman times. Melting—the process of using heat to separate slag and metal, smelting—using a reduced oxygen heated environment to separate metal oxides into metal and carbon dioxide, roasting—process of using an oxygen rich environment to isolate sulphur ...
The ancient bloomeries that produced metal tools for the Nubians and Kushites produced a surplus for sale. All traditional sub-Saharan African iron-smelting processes are variants of the bloomery process. [4] There is considerable discussion about the origins of iron metallurgy in Africa.

The metals of antiquity generally have low melting points, with iron being the exception.. Mercury melts at −38.829 °C (−37.89 °F) [21] (being liquid at room temperature).
