Patterned Pyrex—such as the 1956 Pink Daisy or the 1983 Colonial Mist—also tend to be valuable as a collector's item. Some patterned collections, like the 1959 Lucky in Love heart and four-leaf clover design, have been valued as high as $4,000 for one bowl. But colored Pyrex must look shiny and new.
Pyrex cookware is meant to withstand baking, but it cannot be trusted for use over 425 degrees. This means that for recipes requiring higher temps you should use metal pans. If you use modern Pyrex on a direct heat source, the result will likely be a cracked or exploded piece of glassware.
When ordinary glass acquires some new characteristics due to some tempering and other processes, it is called Pyrex. The tempering process when applied to the finished glass products called Pyrex makes it four to six times stronger than the regular glass product. Pyrex was produced in 1915 by Corning In.
Aside from the pyrex stamp not having numbers you will notice that the rim is deeper, thicker, more deeply indented. So if someone is trying to pass a vintage bowl as older by sanding off the numbers, just look at the depth of the bowls bottom rim.
Identify Pyrex Using Markings and StampsUse the glass markings, stamps, and logos on the pieces themselves to identify when the glass was produced. The oldest Pyrex markings should be on the bottom of glass pieces and feature Pyrex in all capital letters inside a circle with CG for Corning Glassworks.
“While any glass bakeware has a risk of breakage, Pyrex glassware has an exceptional safety record,” Corelle Brands spokesperson said in a statement. In other words, just buying pre-1998 Pyrex cookware doesn't guarantee that it's made of borosilicate glass, and shattering remains a risk.
Model numbers simply designate a particular size and shape of a piece of Pyrex Ware with no regard to color or decoration. Except for the earliest color ware and a few other pieces, they are molded into the piece itself.
Before you decide to donate or toss any of that outdated glassware, think twice: Vintage Pyrex sets have sold for up to $1,800 online. Even single bowls have gone for a whopping $900 and this "Foulard Pyrex mug" on Etsy is up for sale at $800.
Thermal shock occurs when you take something from a cold environment to a hot one. It is acknowledged that Pyrex can explode when this happens.
As you can imagine, promotional Pyrex patterns can be quite expensive. In fact, the Pyrex pattern that's the most in demand can go for upwards of $4,000 and is called Lucky in Love. If you ever find one of these pieces, you'll be lucky indeed.
Before geometric designs became big Pyrex sellers, the Snowflake and Daisy patterns were the first of their kind. Produced from 1956 to 1967, the longest running pattern was snowflakes on a turquoise Pyrex background, while there are also versions of turquoise snowflakes on a white background.
Yes. Almost all vintage Pyrex bowls and baking dishes test positive for lead when using an XRF (a precision scientific instrument that will report the exact quantity of lead, cadmium and other heavy metals found in an item).
These were, primarily, a set of four nesting mixing bowls, with new round casseroles in a handful of sizes following in 1958. Oval open bakers and divided casseroles were also grouped under the Cinderella moniker, although the oval casseroles were not.
Patterns that had short runs are the most collectible because they are rare finds. From the top are Cornflower, the first pattern issued and an easy one to find; Wildflower, made from 1977-84; and Floral Bouquet, made 1971-75.
The results were not pretty–Pyrex had a slight temperature range advantage over Anchor Hocking, but a fairly high percentage of both broke or exploded if they weren't used exactly within the laundry list of restrictions on the cardboard overwrap that came with the new bakeware.
For people worried about making food in plastic containers, glass Pyrex is relatively clean and the vintage pieces are American made. (The modern ones are, too.) And while they're old, they're also surprisingly durable.
Soapy Water: Soak your vintage Pyrex in soapy water, wash with a sponge or dishcloth. Barkeeper's Friend: Scrub with Barkeeper's Friend–1st with a sponge, 2nd with a scrubbing pad. Sharp Razor Blade Scraper: Carefully use a razor blade widget to lift off thick gunk and/or to scrape off surface grime.
