...succession. One evening last week he had three. But it was quite an occasion. Philadelphia's Franklin Institute had opened the first big public showing of Dr. Sando's neat method of preserving biological specimens (and almost anything else, for that matter) in blocks of transparent, synthetic resin...
Better glues were made from casein, a protein ingredient of milk, and from soybeans. In 1912 Dr. Leo Hendrik Baekeland, father of plastics, took out a patent on a synthetic resin for plywood filler, but did not start to exploit it until 1932. In 1926 a German chemist, Dr. T. E. Goldschmidt, developed a filler made of tissue paper impregnated with phenolic resin. This made a bond so firm that the sandwich was stronger weight for weight than steel. It was also waterproof and bacteria-proof...
...three drops of blood are taken from a finger or an ear lobe and centrifuged to remove all red blood cells. Then the clear serum is mixed with several drops of the antigen, a witches' brew of benzoin (a resin from Java or Sumatra), cholesterol (alcohol which occurs in bile), scarlet red (a dye), plain salt water, and alcoholic beefheart extract. If syphilis antibodies are present in the blood, coarse particles develop in the colorless fluid, and clumps of red granules appear around the edges of the mixture. Since the reaction is clearly visible to the naked...

Safety glass is a double sheet with a transparent filler or binding layer between. In the old glass the filler was cellulose acetate. In the new it is polyvinyl acetal resin, a synthetic plastic made from acetylene. In an automobile this flexible, yielding pane is something like a transparent, moistureproof, windproof curtain. It is expected to cut down the number and seriousness of highway injuries due to sudden stops...
