Very early Pyrex glassware, a set of four tiny glass custards that would look just like the old Pyrex lab ware if it wasn't for those wheel cut flowers!
The glass is rather rustic compared to the mid-century vintage Pyrex - these have bubbles in the glass, and one dish has a mold flaw 'straw mark' to the bottom.
The floral pattern is all done by hand with a etching wheel, and is not perfectly identical on these pieces.
All are in good condition showing little if any use, no chips or cracks. These measure about 3" in diameter x 1 1/4" deep.
