As one of the last patterns to exist in the opal Pyrex line, Shenandoah is one of the lesser-known patterns released to the consumer market.

The collection was small and only released on the three-piece Mixing Bowl set (300-80), the Cinderella Bowl set (440-80), the three-piece Bake, Serve and Store set (470-80), and the three-piece Casserole set (480). A four-quart casserole dish was added to the collection in the mid-1980s.

As the popularity of CorningWare and Corelle Tableware grew, interest in the Pyrex patterned opal ware declined. By 1986, when production on all opal Pyrex ceased, Shenandoah was one of four patterns being made.
