Pyrex (<a href="Trademark" title="Trademark">trademarked</a> as PYREX and pyrex) is a <a href="Brand" title="Brand">brand</a> introduced by <a href="Corning_Inc." title="Corning Inc.">Corning Inc.</a> in 1915, initially for a line of clear, low-thermal-expansion <a href="Borosilicate_glass" title="Borosilicate glass">borosilicate glass</a> used for <a href="Laboratory_glassware" title="Laboratory glassware">laboratory glassware</a> and <a href="Kitchenware" title="Kitchenware">kitchenware</a>. It was later expanded in the 1930s to include kitchenware products made of <a href="Soda%E2%80%93lime_glass" title="Soda–lime glass">soda–lime glass</a> and other materials.<a href="#cite_note-1">[1]</a> Its name has become famous for making rectangular glass roasters.

In 1998, the kitchenware division of Corning Inc. responsible for the development of Pyrex spun off from its parent company as Corning Consumer Products Company, subsequently renamed <a href="Corelle_Brands" title="Corelle Brands">Corelle Brands</a>. Corning Inc. no longer manufactures or markets consumer products, only industrial ones.

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<a href="Borosilicate_glass" title="Borosilicate glass">Borosilicate glass</a> was first made by German chemist and glass technologist <a href="Otto_Schott" title="Otto Schott">Otto Schott</a>, founder of <a href="Schott_AG" title="Schott AG">Schott AG</a> in 1893, 22 years before Corning produced the Pyrex brand. Schott AG sells the product under the name "Duran".

In 1908, Eugene Sullivan, director of research at <a href="Corning_Inc." title="Corning Inc.">Corning Glass Works</a>, developed Nonex, a borosilicate low-expansion glass, to reduce breakage in shock-resistant lantern globes and battery jars. Sullivan had learned about Schott's borosilicate glass as a doctoral student in <a href="Leipzig" title="Leipzig">Leipzig</a>, <a href="Germany" title="Germany">Germany</a>. Jesse Littleton of Corning discovered the cooking potential of borosilicate glass by giving his wife Bessie Littleton a casserole dish made from a cut-down Nonex battery jar. Corning removed the <a href="Lead" title="Lead">lead</a> from Nonex and developed it as a consumer product.<a href="#cite_note-IDSAQuote-2">[2]</a> Pyrex made its public debut in 1915 during <a href="World_War_I" title="World War I">World War I</a>, positioned as an American-produced alternative to Duran.

A Corning executive gave the following account of the <a href="Etymology" title="Etymology">etymology</a> of the name "Pyrex":

</style><blockquote class="templatequote">The word PYREX is probably a purely arbitrary word which was devised in 1915 as a trade-mark for products manufactured and sold by Corning Glass Works. While some people have thought that it was made up from the <a href="Greek_language" title="Greek language">Greek</a> <a href="https://en.wiktionary.org/wiki/%CF%80%E1%BF%A6%CF%81" class="extiw external" title="wikt:πῦρ">pyr</a> and the <a href="Latin" title="Latin">Latin</a> rex, we have always taken the position that no graduate of <a href="Harvard_University" title="Harvard University">Harvard</a> would be guilty of such a classical <a href="Hybrid_word" title="Hybrid word">hybrid</a>. Actually, we had a number of prior trade-marks ending in the letters ex. One of the first commercial products to be sold under the new mark was a pie plate, and in the interests of <a href="Euphonism" class="mw-redirect" title="Euphonism">euphonism</a> the letter r was inserted between pie and ex and the whole thing condensed to PYREX.<a href="#cite_note-3">[3]</a></blockquote>

Corning purchased the <a href="Macbeth-Evans_Glass_Company" title="Macbeth-Evans Glass Company">Macbeth-Evans Glass Company</a> in 1936 and their Charleroi, PA plant was used to produce Pyrex opal ware bowls and bakeware made of tempered soda–lime glass.<a href="#cite_note-4">[4]</a> In 1958 an internal design department was started by John B. Ward. He redesigned the Pyrex ovenware and Flameware. Over the years, designers such as <a href="Penny_Sparke" title="Penny Sparke">Penny Sparke</a>, Betty Baugh, Smart Design, TEAMS Design, and others have contributed to the design of the line.

Corning divested itself of the Corning Consumer Products Company (now known as <a href="Corelle_Brands" title="Corelle Brands">Corelle Brands</a>) in 1998 and production of consumer Pyrex products went with it. Its previous licensing of the name to <a href="Newell_Rubbermaid" class="mw-redirect" title="Newell Rubbermaid">Newell Cookware Europe</a> remained in effect.<a href="#cite_note-History-5">[5]</a>

France-based cookware maker <a href="Arc_International" class="mw-redirect" title="Arc International">Arc International</a> acquired Newell's European business in early 2006<a href="#cite_note-hoovers-6">[6]</a> to own rights to the brand in <a href="Europe" title="Europe">Europe</a>, the <a href="Middle_East" title="Middle East">Middle East</a> and <a href="Africa" title="Africa">Africa</a>.<a href="#cite_note-7">[7]</a><a href="#cite_note-8">[8]</a> In 2007, Arc closed the Pyrex soda–lime factory in <a href="Sunderland" title="Sunderland">Sunderland</a>, UK moving all European production to France. The Sunderland factory had first started making Pyrex in 1922.<a href="#cite_note-9">[9]</a>

In 2014, <a href="Arc_International" class="mw-redirect" title="Arc International">Arc International</a> sold off its Arc International Cookware division which operated the Pyrex business to Aurora Capital for its Resurgence Fund II. The division was renamed the International Cookware group.<a href="#cite_note-10">[10]</a> London-based <a href="Private_equity" title="Private equity">private equity</a> firm Kartesia<a href="#cite_note-11">[11]</a> purchased International Cookware in 2020.<a href="#cite_note-12">[12]</a>

In 2021, Pyrex rival <a href="Duralex" title="Duralex">Duralex</a> was acquired by International Cookware group for €3.5 million (US$4.2m).<a href="#cite_note-13">[13]</a><a href="#cite_note-14">[14]</a><a href="#cite_note-15">[15]</a>

In March 2019, Corelle Brands, the makers of Pyrex in the United States, merged with Instant Brands, the makers of the <a href="Instant_Pot" title="Instant Pot">Instant Pot</a>.<a href="#cite_note-16">[16]</a> On June 12, 2023, Instant Brands filed for <a href="Chapter_11_bankruptcy" class="mw-redirect" title="Chapter 11 bankruptcy">Chapter 11 bankruptcy</a> after high interest rates and waning access to credit hit its cash position and made its debts unsustainable.<a href="#cite_note-17">[17]</a> The company emerged from bankruptcy on February 27, 2024 under the previous Corelle Brands moniker, after having sold off its appliance business ("Instant" branded products).<a href="#cite_note-18">[18]</a><a href="#cite_note-19">[19]</a>

In <a href="Europe" title="Europe">Europe</a>, <a href="Africa" title="Africa">Africa</a>, and the <a href="Middle_East" title="Middle East">Middle East</a>, a variation of the PYREX (all uppercase) trademark is licensed by International Cookware<a href="#cite_note-20">[20]</a> for bakeware that has been made of numerous materials including borosilicate and soda–lime glass, stoneware, metal, plus vitroceramic cookware.<a href="#cite_note-21">[21]</a> The pyrex (all lowercase, introduced in 1975<a href="#cite_note-:1-22">[22]</a>) trademark is now used for kitchenware sold in the <a href="United_States" title="United States">United States</a>, <a href="South_America" title="South America">South America</a>, and <a href="Asia" title="Asia">Asia</a>.<a href="#cite_note-23">[23]</a> In the past, the brand name has also been used for kitchen utensils and bakeware by other companies in regions such as Japan and Australia.

It is a common misconception that the logo style alone indicates the type of glass used to manufacture the bakeware.<a href="#cite_note-24">[24]</a> Additionally, Corning's introduction of soda-lime-glass-based Pyrex in the 1940s predates the introduction of the all lowercase logo by nearly 30 years.<a href="#cite_note-Aikins-25">[25]</a><a href="#cite_note-:1-22">[22]</a><a href="#cite_note-26">[26]</a> Nevertheless, all "pyrex" manufactured since 1998 in the United States is soda-lime glass,<a href="#cite_note-27">[27]</a> while all French-made "PYREX" glassware is borosilicate.<a href="#cite_note-28">[28]</a>

Older clear-glass Pyrex manufactured by Corning, Arc International's Pyrex products, and Pyrex <a href="Laboratory_glassware" title="Laboratory glassware">laboratory glassware</a> are made of borosilicate glass. According to the <a href="National_Institute_of_Standards_and_Technology" title="National Institute of Standards and Technology">National Institute of Standards and Technology</a>, borosilicate Pyrex is composed of (as percentage of weight): 4.0% <a href="Boron" title="Boron">boron</a>, 54.0% <a href="Oxygen" title="Oxygen">oxygen</a>, 2.8% <a href="Sodium" title="Sodium">sodium</a>, 1.1% <a href="Aluminium" title="Aluminium">aluminium</a>, 37.7% <a href="Silicon" title="Silicon">silicon</a>, and 0.3% <a href="Potassium" title="Potassium">potassium</a>.<a href="#cite_note-29">[29]</a><a href="#cite_note-30">[30]</a>

According to glass supplier Pulles and Hannique, borosilicate Pyrex is made of Corning 7740 glass and is equivalent in formulation to <a href="Schott_Glass" class="mw-redirect" title="Schott Glass">Schott Glass</a> 8330 glass sold under the "Duran" brand name.<a href="#cite_note-31">[31]</a> The composition of both Corning 7740 and Schott 8330 is given as 80.6% <style data-mw-deduplicate="TemplateStyles:r1123817410">

In the late 1930s and 1940s, Corning also introduced new product lines under the Pyrex brand using different types of glass. Opaque <a href="Tempered_glass" title="Tempered glass">tempered</a> <a href="Soda%E2%80%93lime_glass" title="Soda–lime glass">soda–lime glass</a> was used to create decorated opal ware bowls and bakeware, and aluminosilicate glass was used for Pyrex Flameware stovetop cookware. The latter product had a bluish tint caused by the addition of alumino-sulfate.<a href="#cite_note-32">[32]</a><a href="#cite_note-Snopes-33">[33]</a>

Beginning in the 1980s, production of clear Pyrex glass products manufactured in the USA by Corning was also shifted to tempered soda–lime glass, like their popular opal bakeware.<a href="#cite_note-Aikins-25">[25]</a> This change was justified by stating that soda–lime glass has higher mechanical strength than borosilicate—making it more resistant to physical damage when dropped, which is believed to be the most common cause of breakage in glass bakeware. The glass is also cheaper to produce and more environmentally friendly. Its thermal shock resistance is lower than borosilicate's, leading to potential breakage from heat stress if used contrary to recommendations. Since the closure of the soda–lime plant in England in 2007, European Pyrex has been made solely from borosilicate.<a href="#cite_note-History-5">[5]</a><a href="#cite_note-:0-34">[34]</a><a href="#cite_note-35">[35]</a>

The differences between Pyrex-branded glass products has also led to controversy regarding safety issues—in 2008, the <a href="U.S._Consumer_Product_Safety_Commission" title="U.S. Consumer Product Safety Commission">U.S. Consumer Product Safety Commission</a> reported it had received 66 complaints by users reporting that their Pyrex glassware had shattered over the prior ten years yet concluded that Pyrex glass bakeware does not present a safety concern. The consumer affairs magazine <a href="Consumer_Reports" title="Consumer Reports">Consumer Reports</a> investigated the issue and released test results, in January 2011, confirming that borosilicate glass bakeware was less susceptible to thermal shock breakage than tempered soda lime bakeware.<a href="#cite_note-36">[36]</a> They admitted their testing conditions were "contrary to instructions" provided by the manufacturer.<a href="#cite_note-Snopes-33">[33]</a><a href="#cite_note-37">[37]</a> STATS analyzed the data available and found that the most common way that users were injured by glassware was via mechanical breakage, being hit or dropped, and that "the change to soda lime represents a greater net safety benefit."<a href="#cite_note-:0-34">[34]</a>

<div class="mw-heading mw-heading2"><h2 id="Use_in_telescopes">Use in telescopes</h2></div>

Because of its low expansion characteristics, borosilicate glass is often the material of choice for reflective optics in astronomy applications.

In 1932, <a href="George_Ellery_Hale" title="George Ellery Hale">George Ellery Hale</a> approached <a href="Corning_Incorporated" class="mw-redirect" title="Corning Incorporated">Corning</a> with the challenge of fabricating the 200-inch (5.1 m) telescope mirror for the <a href="California_Institute_of_Technology" title="California Institute of Technology">California Institute of Technology</a>'s <a href="Palomar_Observatory" title="Palomar Observatory">Palomar Observatory</a> project.<a href="#cite_note-glassgiant-38">[38]</a> A previous effort to fabricate the optic from <a href="Fused_quartz" title="Fused quartz">fused quartz</a> had failed, with the cast blank having voids. The mirror was cast by Corning during 1934–1936 out of borosilicate glass.<a href="#cite_note-Caltech-39">[39]</a> After a year of cooling, during which it was almost lost to a flood, the blank was completed in 1935. The first blank now resides in the <a href="Corning_Museum_of_Glass" title="Corning Museum of Glass">Corning Museum of Glass</a>.<a href="#cite_note-40">[40]</a>

According to their calculation and those of others, soda lime glass cookware shatters more frequently because, in theory, it can only resist fracture stress for temperature differentials less than about 55 °C (99 °F). In contrast, they estimate that the borosilicate glassware could tolerate a temperature differential of about 183 °C (330 °F), a three-fold difference.</q></cite></li></ul></li>
