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. Unlike the other 470 series casseroles which have flat, clear lids, it has a clear cover with a knob on it. The color is the reversed white standard pattern on orange-gold.

This has an interesting ID on the bottom which is #664 (cover is 664-C). Also, interesting is that in the few I’ve seen it is marked as both 4 Quarts and 4 Liters. At nearly a foot wide and 4 inches deep, you could cook up a pretty mighty casserole in one of these!
