With the arrival in Britain of skilled metal-workers from mainland Europe around 2500 BC, metal technology began. These people are called the Beaker People, the name arising from their particular style of pottery.
The first metal used was copper, but this was soon replaced by the harder bronze (an alloy of 90% copper with 10% tin), for which the time period, the Bronze Age, is named.
Smiths working in the Peterborough area, mostly in the east, produced hundreds of swords, daggers, spearheads, axes, pins, ornaments and jewellery, such as rings.
The production of metal led to greater control of fire and with it, improved, harder pottery.
