The period in human history beginning in about 1200 b.c. is called the iron age. it was at about this time that humans first learned how to use iron metal. ancient egyptians had learned how to use iron before the first dynasty, which began in about 3400 b.c. the egyptians probably found the iron in meteorites. meteorites are chunks of rock and metal that fall from the sky. some meteorites are very rich in iron. the egyptians made tools and jewelry out of iron. iron was also known to early asian civilizations. in delhi, india, for example, a pillar made out of iron built in a.d. 415 still stands. it weighs 6.5 metric tons. early chinese civilizations also knew about iron. workers learned to produce iron as early as 200 b.c. even from the earliest days, humans probably seldom used iron in a pure form. it was difficult to make iron that was free of impurities, such as carbon (charcoal) and other metals. составьте к тексту 1-4 вопроса. типа: какие изделия изготовляли древние египтяне из железа? где нашли железо древние египтяне? какие древние цивилизации могли получать железо и изготовлять из него изделия? почему люди не использовали железо в чистом виде?
