In archaeology, the Carp's Tongue complex refers to a tradition of metal working from south eastern England in the later Bronze Age.
It is part of the Ewart Park Phase that dates from the ninth century BC.
[2] The period was one where experiments in alloying lead with bronze were being used to develop new artefact types some of which have an uncertain purpose.
[4] Quite why so much experimentation was taking place at a time when iron was increasingly supplanting bronze as the material of choice is uncertain.
Colin Burgess has argued that new techniques triggered a kind of industrial revolution, others that there was an oversupply of bronze that smiths were obliged to find something to do with.
