By analyzing four slags from Bihar and Jharkhand, all in India, we attempted to understand the level of traditional steel-making technology in India. BH-1∼3 can be classified as a tapping slag because it shows traces of flow, whereas JK-1 can be classified as an in-furnace slag considering its dense, flat figure and the existence of iron oxides. Because fayalite appears as a columnar structure in the micro-tissue of the slag, it can be confirmed as a smelting slag, and considering the total amount of Fe and deoxidation agent contents, it can be confirmed that it was created using a direct smelting method. By applying the main component analysis results to the FAS/FCS phase diagram and considering the number of minerals found through the compound analysis, the smelting temperature was assumed to be within 1,000∼1,200℃.
