As far as I know these Delphite Oven Refrigerator Dishes only came in the smaller two sizes of #501 1.5 cup and #502 1.5 pint sizes. It’s very difficult to tell, however, since I’ve only seen a few of these for sale. In any case, this is your normal rectangular Pyrex dish with clear lid but in that wonderful milky light blue color which is often labeled “Bluebelle“. This is in contrast to the Turquoise colored box and the “primary color” blue boxes.

Like I said, these are rather rare (I’d love to have a few of them in my collection). However, there exists an ever rarer variety of this dish that has a LID that is also Delphite. Very interesting, because the entire dish with lid is the same color (and because it is not clear you can’t see what’s in the box… could be why so few were made). When looking for it on Ebay, you might want to try searches like “blue refrigerator pyrex” or “delphite pyrex”. In the past, I’ve only seen the smaller 501 size with the solid Delphite lid, but recently I’ve seen sets including the next size up: #502 1.5 pint with a solid colored lid as well as two of the #501 1.5 cup solid colored lid boxes.
