Comments:

Factory literature reads, " Fine (or True English-bodied) china with the new sculptured look, so durable it's replaced if it breaks, so practical you can cook, bake, 'n serve in the serving pieces."

"Impromptu is the true English-bodied china you've always dreamed of owning - the luxury of true china without dollar extravagance. Noted designer Ben Seibel created the enchanting shapes and patterns that inspire so many table-top fashions for every dining occasion.  With the famous Iroquois cook, bake 'n serve feature, you can add to your culinary accomplishments those wonderfully artistic and appetizing oven-to-table recipes you've always wanted to try.  Impromptu gives new flair to our hostessing, yet makes entertaining so easy on you."

There are two markings, one is a black under glaze backstamp, the other is a colored "sticker."  Do not pass by a piece you know is Impromptu just because it is not marked.  The "sticker" washes off!

Patterns:

In addition to the patterns listed, a set has been found in a blue glaze, no decal. If you have any information on this, please let me know.
