Depression and Elegant Glass / Depression glass is machine produced glass made in America from the mid 1920&#39;s through the 1930&#39;s.  Elegant glass was a bit more upscale, with finishing touches by hand. American made machine pressed glassware, whether pressed or elegant, continued to be produced in abundance up until the 1970s.  Just a few companies to make this glass: Hazel Atlas, Cambridge, (Anchor) Hocking, Tiffin, Federal, Lancaster, etc.  See http://en.wikipedia.org/wiki/Depression_glass for more information. / by Lorie Long
