Show Jar Rubbers Are Different This Year It is now thought that red rubbr will be available for jar rings this year but there will be no cause tor alarm if the rubbers you buy turn out to be black. It is the rubber, not the color, that counts. True, you may be a bit startled when you open your first package of the war models. "But what of it?" asks Gladys Kimbrough, Home Service Director of Ball Brothers Company, "Our grandmothers got along well enough with lipless rubbers and so can we." Months ago, manufacturers began experiments to learn how to make jar rings that would conserve both rubber and food the government ; set its scientists to the same task. One of the first things upon which I all agreed was that lips are unnecessary unneces-sary for opening jars. The point of a thin knife can be run under the rubber to make a tiny space for air to seep through and break the seal. It is then easy to remove cap or lid. It was also agreed that jar rings could be a small fraction of an inch narrower but the thickness must remain re-main at the pre-war standard. War-time rubbers will keep jars sealed air-tight, but they won't stand abuse. To get good results, break yourself of that never-good habit of stretching to test and follow these four simple rules: 1. Wash and rinse rubbers. Boil them to sterilize if you can fruits the old-fashioned open-kettle way. If processing is to be done, drop the rubbers in boiling water and set aside until needed. 2. Have rubbers wet when they are used and be sure that each rubber lies fiat on the sealing surface sur-face of the jar. 3. Partly seal all jars before processing. proc-essing. 4. Screw zinc caps and bands on glass top seal closures slowly when sealing, as quick or jerky turns cause rubbers to slip out of position. |
