Show Plastics Ancient Plastics are generally considered rather new, but their use goes back well over 100 years. First there was the use of natural resins, gums, shellac, and ceiling-wax. In 1846 cellulose nitrate began to be produced. Progress has been steady in the past century until now, if this were not known as the Atomic Age, it might well be called the Plastics Age. Today's plastic spectacle frames, with their rich variety of styles and colors, are a good example of why Plastics are popular. |
