As pandemic restrictions that required mask-wearing and restricted capability for companies of every kind wound down over the previous a number of months, I’d be mendacity if I mentioned the very first thing I needed to do was go to a restaurant. As a substitute, I’ve been longing to spend my days safely wandering the dust-draped aisles of small-town vintage shops and junk retailers of every kind searching for classic Pyrex.
Many people doubtless bear in mind some iconic piece of Pyrex glassware in a mother or grandma’s kitchen. The avocado inexperienced casserole dishes within the “Spring Blossom” print and basic mixing bowls, bought in units of major colours, have held numerous top-secret household recipes and adorned the dinner tables of a number of generations. Now, the timeless serving dishes are having a renaissance of types, due to a thriving secondary market powered by vintage malls, intimate circles of collectors, and naturally, eBay.
Whether or not it’s the resurgence within the mid-century fashionable aesthetic, a collective obsession with all issues classic, or the truth that many imagine in its superior high quality, there’s no denying the enduring attraction of Pyrex.
Pyrex made its debut on the buyer market in 1915, when Corning Inc. revolutionized the at-home glassware market with the introduction of borosilicate glass. Because of the addition of boron trioxide, borosilicate glass is described as “low-expansion,” which implies it’s much less prone to explode in high-heat environments like a ripping scorching oven. It’s additionally much less vulnerable to thermal shock, or breakage that happens in excessive temperature disparities. With the introduction of Pyrex, house cooks may now prep, prepare dinner, serve, and retailer their favourite dishes all in the identical bowl.
Pyrex was so tough to interrupt that an Military sergeant was recognized for betting his fellow troopers a greenback that he may hurl the Pyrex glass at partitions with out it breaking.
The primary Pyrex tableware to hit the market was produced from clear glass. In 1936, Corning acquired the Macbeth-Evans Glass Firm in Charleroi, Pennsylvania, and commenced producing the opaque white “opal glass” that’s now coveted by collectors. Initially, although, these merchandise weren’t supposed for the house — as an alternative, the glass was produced as a sturdy line of “messware,” or tableware for troopers, for the US army. In line with the Corning Museum of Glass, this messware was so tough to interrupt that Harvey Littleton, an Military sergeant and son of early Pyrex builders Jesse and Becky “Bessie” Littleton, was recognized for betting his fellow troopers a greenback that he may hurl the Pyrex glass at partitions with out it breaking.
Beginning within the Nineteen Forties, throughout and after World Struggle II, Corning started courting homemakers with a brand new line of Pyrex obtainable in a variety of colours. The primary iconic items, launched in 1943, are a set of blending bowls in basic major colours — crimson, blue, inexperienced, and yellow. These preliminary colours have been chosen by Lilla Cortright, head of the Pyrex take a look at kitchen. After these first bowls got here a slew of recent items — dinnerware, fridge containers, casserole dishes, and extra — in a variety of colours, together with the enduring pink and turquoise, and pastel yellow.
In line with Jennifer Ashley, creator of an exhaustive Pyrex guide referred to as Shiny Comfortable Pyrex Folks, the corporate capitalized closely on the post-war frugality of People, a lot of whom have been shopping for their first houses within the midst of an financial increase. The model’s fridge dishes, stackable glass dishes with lids, have been touted as a method to save leftovers and cut back meals waste, whereas the glass’s superior warmth retention high quality may very well be described as an early method to be vitality environment friendly and use much less gas throughout cooking. The Pyrex dinnerware was promoted as extra sturdy than different glass plates, a lot in order that gross sales representatives internet hosting dwell demonstrations in shops and supermarkets would climb ladders and drop plates from the highest to point out potential clients that their new purchases wouldn’t break.
For collectors, the Pyrex candy spot runs from the Nineteen Fifties to the late Nineteen Seventies, when the dishes have been nonetheless produced from borosilicate glass.
All through the Nineteen Fifties and Nineteen Sixties, Pyrex continued to provide new colours and patterns for its glass at a powerful clip. The primary patterns, referred to as Pink Daisy and Snowflake, have been launched in 1956. After that, the corporate started to roll out new patterns usually. From 1956 to 1983, Pyrex produced 170 distinct patterns with fanciful names like Golden Honeysuckle, Fortunate in Love, and Pineapple Celebration. For collectors, the Pyrex candy spot runs from the Nineteen Fifties to the late Nineteen Seventies, a time frame wherein the dishes have been nonetheless produced from borosilicate glass and produced in a few of the hottest patterns.
All through this time, different glass producers, like Hazel Atlas and Anchor Hocking, noticed their very own success producing opaque tableware emblazoned with fairly patterns. A lot of these gadgets, like cups and saucers produced from Fireplace King jadeite glass and mixing bowls decked out in cheery polka dots, are nonetheless collectible right this moment. However Pyrex stays the dominant identify available on the market, largely due to the broader vary of distinct, and visually hanging, dishes Corning produced compared to its opponents.
Along with Pyrex made in the US, the molds used to provide best-selling items have been additionally utilized in different international locations, together with the UK, New Zealand, Argentina, and France. These items are particularly common amongst collectors right this moment as a result of they’re extra uncommon and aesthetically distinct from American Pyrex.
Within the mid-Nineteen Eighties, manufacturing of Pyrex opal glass in the US all however ceased for causes that stay unclear. Maybe opal glass was now not worthwhile for the Corning Glass Firm, or possibly curiosity within the brightly coloured dishes had waned. In 1986, the corporate started producing clear glass bowls that have been painted with stable colours and patterns, and bought some U.Ok-produced opalware within the States. In 1998, Corning bought off its housewares division to concentrate on producing glass for different industries, like scientific analysis and know-how.
What occurred subsequent is the supply of some main controversy. Following the sale of the Pyrex model to World Kitchen, Inc., now generally known as Corelle Manufacturers, some Pyrex followers say the method modified dramatically. After 1998, all Pyrex merchandise have been made with soda-lime glass, which many imagine to be vastly inferior to the energy and thermal-shock-resistant properties of borosilicate Pyrex. Whether or not or not that’s the case is up for some scientific debate. Quick ahead to 20 years later, and Pyrex was slapped with a class-action lawsuit in 2019, alleging that the soda-lime glass merchandise have been vulnerable to breakage and even exploding.
Following the sale of the Pyrex model to World Kitchen, Inc., now generally known as Corelle Manufacturers, some Pyrex followers say the method modified dramatically.
In line with NBC5 Chicago, greater than 850 cases of this new Pyrex glass exploding or shattering have been reported to the Shopper Safety Security Board over the previous decade, although Corelle Manufacturers insists that its merchandise have an “wonderful security report,” and that soda-lime glass was generally used to make Pyrex all through the a long time. Litigation over the allegedly exploding glass continues to be pending.
However nicely earlier than the exploding Pyrex scandal, the basic opal glass was discovering a resurgence amongst collectors and people obsessive about the midcentury fashionable aesthetic. And as with the remainder of the rise of mid-mod, Pyrex’s rising recognition will be owed in a single pop-culture phenomenon: the tv present Mad Males, which spans the ‘60s by means of the lens of a Madison Avenue promoting agency. In line with Ashley, curiosity in classic Pyrex surged following Mad Males’s 2007 premiere, and solely continued to develop as followers watched watched Joan Halloway put together dinner together with her Pepto-pink casserole dish and Betty Draper set out get together snacks in poppy-red bowls.
“The buddies I’ve made within the Pyrex group have been amassing for 20 or 25 years, they’re long run collectors,” Ashley says. “I believe I’m late to the sport, as a result of they’ve mentioned that Mad Males undoubtedly introduced some new curiosity. After which got here Mrs. Maisel.” Ashley’s referring to Amazon streaming sequence The Marvelous Mrs. Maisel, a few rising comic within the Nineteen Fifties. Within the present, titular character Midge Maisel serves her brisket in a Pink Daisy Pyrex casserole dish, the identical favored by Joan in Mad Males, sparking renewed curiosity in one of many earliest Pyrex prints.
With elevated curiosity has come critically elevated costs. In line with Ashley, many early collectors have been scoring uncommon items at thrift shops and storage gross sales for a couple of bucks every. “The market is certainly completely different,” she says. “You may have extra competitors for each bit, particularly amongst collectors, and thrift shops like Goodwill now have their very own public sale websites. They’re pulling issues straight from the donation pile and sending them straight to public sale as an alternative of placing them out on the shelf for collectors to seek out.”
“My grandmother and my mom each cherished Pyrex, and as I began researching and studying extra about completely different patterns — and completely different patterns made in numerous international locations — I fell onerous and quick.”
For Nate Smith, a steerage counselor at Dallas’s Booker T. Washington Excessive College for the Performing and Visible Arts and a comparatively new — however severe — Pyrex collector, the hunt is a part of the attraction. His curiosity within the model started in earnest final yr, as he sorted by means of his mom’s belongings. “It was an unintended, generational obsession,” Smith says. “My grandmother and my mom each cherished Pyrex, and as I began researching and studying extra about completely different patterns — and completely different patterns made in numerous international locations — I fell onerous and quick.”
Since starting his Pyrex assortment final fall, Smith estimates that he’s collected near 1000 bowls, casserole dishes, storage containers (or “fridgies,” as they’re recognized within the Pyrex world) and different Pyrex necessities. He’s pursued uncommon patterns and promotional gadgets internationally, scouring on-line resale teams and public sale websites for the items he seeks. Just lately, he scored one in every of his most coveted items — a big casserole dish within the “Cloverberry” print. Smith wouldn’t dish on what he paid for the dish, however directed me to eBay, the place current gross sales figures point out that the identical casserole bought lately for upwards of $1300.
Smith can also be a vendor, who often re-homes classic finds of every kind — not simply Pyrex — that he doesn’t wish to hold through the net buying platform Mercari. Whereas vintage malls, thrift shops, and different resale retailers are stable locations for Pyrex looking, most collectors ultimately have to show to on-line retailers like eBay, Etsy, and Fb Market to seek out less-common items. “You may get fortunate going right into a thrift retailer or an property sale, however if you need one thing uncommon, you’re going to have to buy on-line,” Smith says. “When you’re not keen to do this, you’re going to be ready round a very long time.”
Costs within the Pyrex market are set by the 2 elements that information most markets: demand and rarity. All through the a long time, Pyrex produced a slew of promotional gadgets and limited-edition patterns in small portions, and people are critically coveted by collectors. Proper now, Smith is searching for a uncommon casserole dish produced by Pyrex in 1962 to commemorate the opening of New York Metropolis’s Lincoln Middle. Different promotional gadgets have been produced as a part of stamp redemption packages like S&H’s Inexperienced Stamps, the place customers at grocery shops would acquire stamps as they bought their milk and bread to earn mixing bowls and different housewares.

In line with Ashley, there are some prints so uncommon that just one or two items of every have ever been seen by collectors within the wild, like an ocean-inspired sample nicknamed “Angelfish.” Different uncommon, coveted items have been prototypes that by no means went into full manufacturing, and there are additionally people who appear to have been produced by artistic Pyrex designers given free-reign. “I believe loads about how a lot autonomy the designers had, and what they have been doing of their downtime,” Ashley says. “As a result of there’s fairly just a few one-offs. It’s only a matter of the one that has it, and whether or not or not they wish to share it.”
In what might come as a shock, many severe fans by no means truly use their Pyrex to prepare dinner with, together with Smith. “The individuals who purchased them initially purchased them to make use of them, as a result of individuals of that technology in that point interval might not have had more money for present items,” he says, emphasizing that plenty of Pyrex customers nonetheless see their collections as extra sensible than valuable. “Now, contemplating that so many of those items are handed down from technology to technology, if any individual noticed their dad and mom utilizing them, they’re going to make use of them. Over time, they see that the items are nonetheless okay and so they use them once more, or if one breaks, it’s not an enormous deal. Issues will be changed.”
