I think I have solved the glassware that was sold in parties ,as in like a Tupperware party question, Tiara Glass was made from 1970 to 1998 using old Indiana Glass Company and Duncan Miller molds. Tiara glass was produced by Indiana Glass and other glass manufacturers and sold through the Tiara home party plan. Boxes and stickers bore the Tiara name. Tiara Sandwich dinnerware was made in the following colors: Ruby (limited quantities), Amber, Crystal, Bicentennial Blue (sometimes called Colonial or Midnight Blue) , Chantilly (pale green), Peach (sometimes called pink, but the official name was Peach), and Spruce (teal). A few items were also made in other colors. The Tiara company ceased production in late 1998. However, Tiara Glass in Plum was offered by Home Interiors during 1999 and 2000.
