Ground Glass
in the early '70s i resurrected an old multiple-blank machine that could b
"programmed" with cam-driven grinding wheels to produce votive candle-holders.
each piece was unique, as the old machine had so much slop in it
that no 2 were ever the same;-) i imagine it's still sitting somewhere in the
cold-end of the smith factory...also note that the sprayed red color is coming off.
