REPAIRING BROKEN OILSTONE.
(a) Heat the broken pieces, on a hot plate or
satisfactory manner, to drive all oil from inside the stone.
(b) Scrub the broken edges with a dry cleaning solvent to remove
gum and dirt.
(c) Dust the broken edges thickly with flaked or ground orange
shellac. Carefully work shellac into all cracks and openings.
(e) Clamp pieces together until cooled.
(f) Dress the stone until the joint is smooth and true.
Oilstones must be carefully put away in a box or on
special racks when not in use. Never lay them down on uneven surfaces or
place them where they may be knocked off a table or bench, or where heavy
objects can fall on them. Do not store in a hot place.
