  <dc:description>&#x201C;Crystals and Glass&#x201D; is one of fifty-three short educational films originally produced in 1955 for KQED San Francisco as part of the series Tempest in a Test Tube. This series of half-hour episodes illustrates basic chemistry concepts for high school students through live experiments and demonstrations by presenter Dr. Harry Sello. The experiments used in the show were designed by the American Chemical Society&#x2019;s California chapter and reflect the safety standards of the time. This episode, &#x201C;Crystals and Glass,&#x201D; teaches viewers how and why crystals form and shows how different factors affect the behavior of glass and crystals.</dc:description>
