Katy is another interesting pattern with contradictory naming depending on which reference book you use. Imperial made Laced Edge in many colors, including this lovely deep ruby, but as Gene Florence notes, much of colored glass except for opalescent green and blue occurred after the depression.
Florence restricts “Katy” to the Laced Edge made in the 1930s, noting this means opalescent green and blue.
Hazel Marie Weatherman calls the Laced Edge shape either Sugar Cane or Katy, with the Sugar Cane having a cane design on the centers and sides. I’m guessing that the red bowl above and green bowl shown below are Sugar Cane and the blue is Katy.
The Sugar Cane page reproduction shows Imperial made it in 6 colors, crystal, Stiegel green, Ritz blue, amber, rose pink and Imperial green. Per the Imperial Glass Encyclopedia by Measell, Imperial did not differentiate between the cane and diamond designs and called them all Laced Edge – albeit with multiple line numbers.
Florence shows a Katy Blue dinner set, complete with plates, small bowls, cups and saucers, even tumblers, plus accessory and serving pieces. I’ve never seen anything other than a few accessory pieces like the bowls shown. My guess is Imperial didn’t sell too many of the dinner sets; three salad plates or soup bowls were 20 coupons or $.90, a sizable sum in the 1930s.
Plates and bowls for table use lack the delicate arched laced edges and instead have more substantial pierced rims with molded arches. Personally I’d not want to use a plate with the thin arches; the pierced rims would be sturdier. Tumblers and cups are smooth around the rim with molded arches below a plain band.
Laced Edge is another Imperial pattern where it would be rewarding to collect just a few pieces in the colors that appeal to you. The bowls are lovely and are excellent for a touch of color or to hold candy or nuts.
