Seville debuted on the consumer market in 1971 and was available in 1972. Listed in the “Gifts” section of the 1972 Pyrex catalog Seville retailed at $7.95. The 2 ½ quart Oval Casserole (045) came with a double candlewarmer.

Seville has a tangerine colored dish with a white opalware lid printed with red and orange stylized floral flourishes. Seville was discontinued in mid-1972 and was the most expensive single Pyrex dishes available at the time, matched in price only by the three-piece casserole sets.

Corning Glass Works offered its first patterned opalware gift set in 1953 when the Heinz Baking Dish was sold in grocery stores. Widespread distribution of promotional patterns occurred after the overwhelming success of the 1956 release of seasonal “decorator casseroles.” Using existing Pyrex shapes, gift sets featured new patterns offered for a limited production time. They often came with mounters, cradles, or candlewarmers and were advertised in the spring to appeal to Mother’s Day and summer wedding shoppers and in the fall to give the holiday gift-buyers something new. Corning continued to produce gift sets through 1983, creating nearly 135 different gift set patterns during that time. Corning intended these pieces to be sold for a limited time, and directed retailers to remove older, unsold promotions from the shelves.

Often, patterns used for these gift items were unnamed, or given names descriptive of the dish’s purpose, like “chip and dip set.” Collectors over the years have assigned names more reflective of the specific pattern.
