FLINT RIDGE FLINT
RAW FLINT ON LEFT & HEAT TREATED
ON THE RIGHT
RETURN TO PAGE TWO
These Flint Ridge flakes show the dramatic
contrast in color before
and after heat treating. The
flakes on the left are unaltered as
they appear from
the Flint Ridge quarries. The more colorful flakes
on the right were altered by heating the preforms.
Roy uses an electric kiln to heat treat his flint. The
process takes from three to four days before the
preforms are removed from the oven. He programs
the kiln to slowly heat 25 degrees per hour until it
reaches a maximum of 500 to 550 degrees. He can
control the temperatures close enough to bring out
more of the yellows at a slightly lower temperature
and more of the reds with a higher temperature.
All of these flakes were quarried from Roy Miller's
property which is part of the ancient Flint Ridge
quarry complex in
eastern Ohio.
