Burning Rock. Experiments with fire setting (without music) @perstoremyrarchaeologycons3975

Per Storemyr Archaeology & Conservation In the Melsvik Stone Age chert quarries near Alta in Northern Norway there are dozens of extraction marks that are difficult to explain by other ancient techniques than fire setting. Hence within the Melsvik archaeological project, run by the University Museum of Tromsø, last week we experimented with fire in order to substantiate that it actually formed an important method of breaking loose small and big pieces of stone. The idea was that it is not necessary with big fires and high temperatures, but that small, controlled "bonfires" are enough to create high shear stress and cracking. In this way high temperatures greatly reducing the quality of the chert for tool making are avoided. It works!
