Fostoria had a long tradition of making stunning glass shapes that they used for decorations and sold undecorated for dinnerware and more. During the 1950s and into the 1970s Fostoria’s go-to pattern was Century.
These saucers show the design. Century pieces are round; cups and some serving pieces are footed and the primary design element is the curlicue rim. You can spot Fostoria Century by the little C shapes (C for Century).
Fostoria made a full dinnerware set in crystal with a few pink pieces. The stemware is a little clunky for my taste but the bowls and other accessories are lovely with graceful shapes.
Heisey’s Lariat pattern was the closest in looks. Lariat had large loops on the rim like this caramel dish.
Heisey made a full line of dinnerware, stemware and accessories in Lariat and they used it for decorations too. I have only ever seen accessory pieces like the caramel dish above and the marshmallow bowl (yes, really, a bowl for marshmallow) below.
Athena is another Heisey pattern that is similar with a curlicue rim, except Athena used S shapes. Heisey made it earlier, in the 1940s and I don’t think it was as successful as Lariat since we seldom see pieces.
