Development of Technology Ferrous Metal Melting Furnace Ancient Times in Indonesia

Abstract. Technological knowledge of the use metals is inseparable from human in processing pyrotechnics fire as a power high temperature processes for producing objects. The used smelting and casting melting furnaces. Metal furnace heat production device, which to purify metal, this case iron. This paper aims determine development ferrous metal technology Indonesia with library research method results previous studies. Based on analysis, there are four technologies iron, namely pit kiln, bloomery furnace, blast induction furnace. Of technologies, three Indonesia,
