If the defect is very slight, how- ever, it may be remedied by pressing a knife handle on the lower edge against a hard surface, thus straightening the offending bulge. Another test is made by putting on the rubber, screw- ing the top on tightly and then pulling the rubber out. If the rubber returns to place, the top does not fit and should not be used on that jar. 3. Vacuum seal jars may be tested in the same way as the glass-top jars. See if the tops rock if tapped, when placed on the jar without fastening. STANDARDS AND TESTS FOR RINGS 1. Good Rubber Essential.—Buy new rub- bers every year, as rubbers deteriorate from one season to another. A good rubber for Fig. 9. Wire rack for Fig. 10. Simple test for rubbers. A perfect rubber will show no crease or break after being folded tightly several times. cold-pack canning must be such as to stand four hours of continuous boiling or one hour under 10 pounds of steam pressure. The combination of moist heat plus acids and mineral matter in vegetables and fruits tends to break down the rubbers during steriliza- tion. Rubbers kept in a hot or very warm place, as for example, on a shelf near the kitchen range, will deteriorate in quality. Be very particular about the rubbers used. Spoilage of canned goods has been traced frequently to the use of poor rubbers. 2 Testing Rubbers.—It is always well to test rubbers when buying. A good rubber will return to its original size when stretched. It will no
