To Bore Holes In Glass
Any hard steel tool will cut glass with great
facility when kept freely wet with camphor dissolved in turpentine. A
drill bow may be used, or even the hand alone. A hole bored may be
readily enlarged by a round file. The ragged edges of glass vessels may
also be thus easily smoothed by a flat file. Flat window glass can be
readily sawed by a watch spring saw by aid of this solution. In short
the most brittle glass can be wrought almost as easily as brass by the
use of cutting tools kept constantly moist with Camphorized Oil of
Turpentine.
