      China had bronze early on
      Science Alert [Australia], 03 December 2009

      ANSTO research has shown that an area of desert in north-western China
      was once a thriving Bronze Age manufacturing and agricultural site. The
      new findings may help shed light on the origins and development of the
      earliest applications of Bronze Age technology. Dating, using ANSTO's
      precision techniques, was used to identify the age of seeds, slag,
      copper ore and charcoal at two sites. The findings show the material is
      up to 3700 years old, but that smelting was still being carried out as
      recently as 1300 years ago. The research indicates bronze production may
      have begun as early as 2135 BC and that the modern mine location -
      Baishantang at Dingxin - was possibly the historical source of copper
      ore for manufacturing.
