Abstract: In the history of human evolution, the emergence of ironwares promoted the development of productive forces by leaps and bounds. Primitive iron was obtained by the method of reducing iron ore with solid carbon, i.e. so-called'bloomery process'. Furthermore, various kinds of farmigng implements, tools and weapons could be manufactured by forge welding technique with bloom as raw materials. The ancient forge borge welding technique of bloom appeared in an embryonic forms of modern P/M technique, in other words, the latter was revived and developed from the former but has reached a new level.
The paper has sumed up the emergence and development of ancient bloomery process and discussed its relation with P/M.
