The Hittites - Iron smelting before the Iron Age

2014-7-28  Iron probably was not the mythical secret weapon which explained Hittite military success. However, they did develop a smelting process capable of producing iron tools, weapons, and ornamental objects. Their process was the result of years of metal-working experience, not simply an accidental byproduct of an iron

Ancient Metallurgy - University of California, San Diego

2021-7-20  It was not until about 1200 BC that iron became general for the production of tools because the temperatures needed to process the ore exceeded what most ancient kilns were able to reach. Pure iron has a melting point of 1,535°C. The limit of an ancient furnace was about 1,150°C. (Recall, by contrast, that copper has a melting point of 1,083°C. Ancient pottery kilns sometimes also reached

Iron Smelting 101 – Harald the Smith

Iron Smelting 101. One of my specialties as artisan, research and demonstrator is bloomery iron smelting. An ancient method of iron production, which consists of gathering iron ore and then smelting it in a clay shaft full of burning charcoal. The result is called a ‘bloom’ – a spongy mass of white hot iron
