Pattern: Butterfly Gold
Identifiers / Alternate Names: Various butterflies and five petaled flowers. Most commonly a yellow-brown pattern on white, though the reverse of white on yellow-brown also exists. Two distinct pattern variations exist for various items - one has just the butterflies and flowers while the other has those items embedded on "wheat stalks", much like the Autumn Harvest pattern. Some lids feature a ring of butterfly gold with a single flower in the center, and the smallest size refrigerator box contains a single flower. Some other items (mugs and some casseroles) may not have butterflies in the pattern and only flowers. Also known as: Golden Butterflies, Five Petal Flowers

Sizes and ID#s: #664 (4 quart / 4 liter casserole with lid)
This is one of the more unusual items in the popular Butterfly Gold series of Pyrex dishes. It’s a rather deep four quart round casserole with the pattern on it. The dish has a flat rim encircling it which is different than most other shapes - it sort of looks like the rim on the round Pyrex butter tubs.
Unlike the other 470 series casseroles which have flat, clear lids, it has a clear cover with a knob on it. We’ve seen several cases where the cover is a sort of finely mottled, bumpy texture. In addition, sometimes the knob is square and other times it is round. The color is the reversed white standard pattern on orange-gold.
This has an interesting ID on the bottom which is #664 (cover is usually 664-C). Also, interesting is that the one we have and most others we’ve seen are marked as both 4 Quarts and 4 Liters. The full stamp on bottom of ours says: “664 4Qt - 4l / Pyrex By Corning Corning NY USA / Baking & Microwave Only.”
At nearly a foot wide and 4 inches deep, you could cook up a pretty mighty casserole in one of these! Actually, below is a picture with a standard 1410 mug inside of it to show the scale.
