Butterprint was one of the first printed patterns on the opal ware Pyrex line, preceded only by Snowflake and Pink Daisy. Released in 1957 Butterprint was the result of growing market trends with its turquoise on white and white on turquoise Amish print. Along with Gooseberry, Butterprint was one of the first patterns debuted on the new “Cinderella Bowls.” Cinderella Bowls were a series of large nested mixing bowls with a handle or spout on each side, and designed by John Philip Johnson. The name Cinderella was applied to quite a few different Pyrex products from carafes to butter dishes even though the new spout and handle nesting bowls marked the first use of this name.
