Which takes the temperature of a battleship? The thermometer with wires attached. (5) It hangs in the powder magazine and long before the temperature there reaches the dan ger point, the mercury inside the tube makes an electrical connection and sounds an alarm. The right-angle thermometer (3) is screwed in the side of a milk-pasteurization tank. It tells when milk has reached the proper heat for killing harmful bacteria. And the long thin one (4) is used by research chemists. The stubby model (2), made to register only low temperatures, is to put in your home freezer. Poke the meat thermometer (6) into a beef roast in your oven. When the thin black line pushes up to "Medium Rare," you can take your roast out-sure the slices will be pink and juicy. And everyone recognized the fever thermom eter (1) which your doctor uses when you are ill. These are only a few of the more than 1000 kinds of glass thermometers made from tubing manufactured by Corning Glass Works. The accuracy of a thermometer depends to a great extent on the uniformity of the tiny bore which runs the length of the glass tubing. Making a short length of tubing with a bore 1 the diameter of a human hair is difficult enough. But Corning turns out mile after mile of such precise and uniform tubing. Thermometer tubing is but one of thousands of products that have resulted from Corning's research in glass-researchto develop the right kind of glass for the job, research to develop new ways to make glass precisely by mass production in order that it can be used for wide spread product and process improvement. If you are planning new products or processes, it will pay you to call on Coming before you reach the blueprint stage.
