One Of The Most Valuable Vintage Pyrex Pieces To Keep An Eye Out For While Thrifting

If you have a few Pyrex pieces in your kitchen right now, you're not alone. This massively popular cookware brand has been around since 1915, when it helped introduce borosilicate glass — loved for its ability to handle extreme temperature changes — to the public. But by the middle of the 20th century, Pyrex became known for more than just its temperature durability; it also made a name for itself in design. Postwar consumers were buying houses at a record rate and wanted their new homes' interiors to reflect their tastes. Pyrex met that demand with pieces that were functional and also beautiful, featuring bright colors, matching sets, and trendy patterns. 

Like other well-made, attractive products of the past, Pyrex has cemented its place in popular culture as a nostalgic collector's item. Some pieces from the brand are worth more than others — case in point: the Starburst Cinderella Casserole. It's a rare vintage Pyrex dish you'd be lucky to find at thrift stores. This dish has an ideal combination of features that make it worth hundreds, if not a thousand dollars, (depending on its condition). If you see it at the thrift store, grab it immediately.

The "Starburst" pattern, as collectors call it, was produced for just a year, adding to its rarity and mystique. It came out in the early 1960s, during Pyrex's production of "Cinderella" products (which were likely influenced by the Disney movie that debuted in 1950). With its cosmic motif, it's the epitome of atomic-age design: a look that continues to hold visual appeal for many collectors. Plus, the casserole is a highly functional piece. Its shape is intended to save space on your countertop or in your oven, and its flared handles make pouring and handling more ergonomic. 

This special Pyrex piece is most commonly found in its turquoise incarnation, but extremely lucky thrifters may discover it in black. (Here are the best thrifting tips to help increase your chances.) If you've really hit the jackpot, you'll find this casserole dish with its accompanying glass lid or its elevated warming stand, designed to hold two candles.

You'll know you've found The Starburst at your thrift store if its bottom says "PYREX," with the model number "575-B." The bottom will also denote that the casserole holds 2 quarts and is made in the USA. Keep an eye out for the 550C glass lid that goes with it as well. If you find the accompanying warmer in its package, it'll have model number "575CW."

If you're paying thrift store prices, the Starburst is worth picking up in just about any condition, though it will be worth the most if it is free of chips and stains and comes with its glass lid and warmer. If it's in its original packaging, its value increases more. It's worth taking to an auction house, a midcentury glassware specialist, or a certified appraiser to get an idea of its value. But in good condition, this piece can have a value ranging from about $500 to over $1,000.
