The stone and stencil
is now moved over conveyors into one of the sand-carving
booths. The operator stands behind a shielded opening,
directing a stream of abrasive that is blown under pressure
of about one hundred pounds per square inch. When the
abrasive strikes the rubber, it merely bounces off;
but where the rubber has been cut away, the abrasive
etches the pattern into the granite. This one-step method
is used to produce letters and other two-dimensional
designs. Although sand-carving has reduced the need
for hand-cut letters, it has not eliminated the artistry
required to produce fine lettering. Rock of Ages’
expert sand-carvers produce deeply sunk lettering with
sharply defined edges.
