7—SURE TO ‘SEAL TIGHT:
DO NOT SEAL THE JARS TIGHT
WHILE THEY ARE BEING USED TO

STERILIZE PRODUCE.

ADHERE STRICTLY. TO THE TIME
GIVEN FOR EACH FOOD.

In using Perfect Seal jars put the cover in
place over the rubber ring, and leave THE
CLAMP or SNAP up. The jar cover must
NOT BE TIGHT DURING STERILIZING,
because air expands when heated, and if the
cover is not sufficiently loose to allow the
steam to escape, resulting pressure may blow
out the rubber ring or break the jar. In using
Screw Top jars (GEM, CROWN or BEST)
screw the cover down over the rubber ring
until it catches, THEN TURN IT BACK
ONE SIXTEENTH OF A TURN. Another
way is to tighten as much as possible using the
thum and little finger without force. After
following canning instructions as given in the
body of this booklet, put on rubbers and tops
then adjust as described above according ‘to
the style of jars used. When sterilization is
completed, press down the spring on the

Perfect Seal or screw the metal ring TIGHT
on screw jars, i.e, GEM, CROWN or BEST:

TESTING

Before using the jars the following

tests are recommended ;—

1—Remove the rubker ring, place the glass
top in position on the jar, then by tapping
or by a rocking motion on the neck of the
jar be satisfied that the lid seats itself
evenly all round. Whenin doubt pour about
two inches of water into the jar, replace
rubber ring and after sealing tightly, turf
upside down and shake vigorously. If the
jar leaks do not use it.

2—Examine the top of the jar and see that
there are no rough edges. If there are:
these should be scraped off before using.

3—The Wire Bails or Lightning Fasteners on
Perfect Seal jars should fit into place with
a slight snap and exert sufficient pressure
to hold the lid firmly in place.

The pressure on the lid can be adjusted by
turning the hinge, where the bail is fastened
to the neck wire, to or from the point marked
“TIGHT” on the neck of the jar. SEE
ILLUSTRATIONS.

If the BAIL does not fit properly it should
be taken off the neck wire and bent or straight-
ened until it acts as indicated.
