Peculiar color. Peculiar insulator. Doug Williams list this CD 724 as one of the favorite insulators in his collection of threadless glass. The color is described in the price guide as "clambroth w/ purple tint". Seems a very apt description for this example in particular, with the bubbles and swirls giving the piece a liquid appearance. The insulator is base embossed CHESTER N.Y. Like CD 723's, the 724's also had a wooden cover to protect the glass from damage.
