Neolithic Matches
Researchers from Israel say that mysterious clay and stone artefacts from Neolithic times could be the earliest known "matches".
(8000 yrs ago)
The research was published in the open access journal Plos One.

By using electro-microscopy techniques, Prof Goren-Inbar and her colleagues identified tell-tale signs that the cylindrical clay objects may have been rotated at high speed, generating friction to ignite tinder.

They identified linear marks, or striations - at the conical ends of the cylinders which they interpret as being generated by spinning the "matches" within sockets found on "fire boards", which are known from other sites. Burn-colouration reminiscent of scorch-marks was also found, as well as grooves evident higher up the objects, which may have been generated by a bow, used to spin the cylinders.
