Using Fire to Make Tools | The Great Human Race

on this journey we need to carry grains
milk water processing number materials
directly on a fire so I want to make
some clay pots prior to the invention of
pottery our ancestors used organic
containers such as animal stomachs and
baskets to store and process food but
now with the invention of pottery we had
the ability to cook and process food
directly on a fire we’re no longer stuck
with just a few cooking options we can
now make soups and broths and stews we
can throw a whole bunch of things
together and make one meal in one pod
these pots really make all the
difference for us my plan is to turn
this copper into a knife the first metal
blade I’ve had you dig into the coals
and find the hottest spot to put this by
five thousand years ago we were no
longer reliant only on stone wood and
bone for tool making we began to shape
metals into knives and Spears giving
rise to the Bronze Age this is
revolutionary for humans this gave us
strong tools tools that we could use and
reuse over and over again you heat up a
metal until it’s red-hot
the copper becomes soft and more
malleable and then cool it down quickly
and as soon as it’s cool that can be
hammered
can tell it’s thinner already that’s
gonna be a great knife along this edge
so now I’ve just got to put a handle on
it
my next step is to raise this
temperature slowly in these pots until
they’re at the point that they’re fired
and they’ve turned to ceramic once these
pots are preheated I’m spreading out the
fire I place the pots on the ground in
the middle and then build the fire back
over top of the pots I’m continuously
adding wood to this fire until I’m
convinced that these pots chemically
changed from clay to ceramic
