So I knew I would not be able to resist the lure of writing about the elements. But I began to see also that an introduction to the elements need not after all become a tour of the Periodic Table—which anyway others have conducted before me, and more skilfully or more exhaustively than I would be able to manage. The story of the elements is the story of our relationship with matter, something that predates any notion of the Periodic Table. Intimacy with matter does not depend on a detailed knowledge of silicon, phosphorus, and molybdenum it flows from the pleasurable density of a silver ingot, the cool sweetness of water, the smoothness of polished jade. That is the source of the fundamental question what is the world made from ... 

Both fractions obtained from crackers extracted less than one week after baking had strong cracker-like aromas. The Freon 113 fraction had a cracker, roasted grain, cooked rice aroma while the ethyl acetate fractions had a cracker, sweet baked good, burnt butter aroma. A preliminary analysis of the two fractions by gas chromatography-mass spectrometry on a 25 m by. 22 mm methyl silicone column between 700 and 1800 retention indices showed the compounds listed in Table 2. 

Most of the silicone rubbers used in the food industry are based on polydimethyl vinyl silicone and these materials have very good high- and low-temperature properties. It is their high-temperature resistance that enables them to be used for seals and tubing, for example, in drinks vending machines up to 100 °C. Cold cured silicones are used as release coatings on items such as food transportation belts and for sweet moulds.
