The Story of Borosilicate Glass: Why Pyrex was Special

[@Cracktune]

bought 'pyrex' thinking back to my grandmother's adoration for her glass bakeware. Mine shattered ruining a holiday meal... research then thrift store hunting I have now replaced my 'pyrex' with PYREX. Be aware and beware. Great video. Sub'd

Thats not an indication of anything, educate yourself a little harder. Both spellings used both materials at times.

[@tseksloquet1532]

Somehow stumbled across this video while googling what exactly the borosilicate in dab rigs and bongs was. This is a super dope corner of youtube and you sir are a wonderful human for sharing this knowledge! Thanks for the deep dive into mat sci.

Originally it was marketed as Nonex (Non Expanding) and was first sold in the form of Railroad Lantern Glass, it was hot, but had to handle snow and rain hitting it.

[@suzannaflores1164]

Wow cool!!!!

[@PotionsMaster666]

Damn son, where did you find this !?

[@mightyst3v]

1908 corning sold nonex branded glass actually for pharmaceutical companies wheter it was also for railroad lanterns i couldnt check anywhere on the internet

[@MadisonKirkman]

@@mightyst3v It should be pretty easy to find, alongside being part of the major history of Corning Glass company, The MythBusters did a promotional commercial for Corning Glass Company talking about this history. Also plenty of lantern Globes turn up with the Corning nonex logo.

Thank you for this very informative video. I work in the Flat Panel Display equipment industry and you will be happy to know that actually all the TV's, Monitors, LCD LED displays, etc. use Corning's Borosilicate glass. In some cases these panels are heated to over 500°C temperature. They are very thin .35mm to .7mm thick and can withstand quiet a bit of abuse during the processing. they are very large sheets up to 110,000 cm² or 11m².

As a Boro lampwork glass artist I appreciate this in depth explanation of the glass I love working with so much. Borosilicate glass is used almost exclusively in the Functional Glass arenas (ie...pipes and other items for the pot smoking industry). It is a fantastic material for creative flame glass working as it easy to work with and produces strong products and works of art. I have a couple questions.... is CTE and COE the same? In Flameworking we refer to COE = Coefficient Of Expansion. I assume that’s the same as your CTE??? Hard glass (Borosilicate) has a COE of 33; Soft glass (Sodalime) has COEs ranging from 90-104. How do the COE numbers relate to the temperatures they are affected by? Boro needs much higher temps to melt but has lower COE. Soft glass melts at lower temps but has much higher COE numbers. THANKS

[@vansskater692]

Yes

[@irisjones737]

Hi, friend, do you have a social media account for glass art? Because i like glass art too.

[@andyhsong]

i believe borosilicate pipe makers are also responsible for pioneering alot of modern flameworking techniques and spurred the creation of a ton of crazy new colors for artists to work with. i think its pretty amazing!

[@lindacondray7918]

@@irisjones737 Sorry, unfortunately, I’m one of those old fuddy duddies who only has a very outdated website. I’d rather be creating with my glass than keeping up sod media channel pages. LOL

[@janetk3015]

thank you for sharing! Very good explanation. I liked especially how you encouraged people to hold onto the original PYREX measuring cup. I have the pyrex in soda lime. It's still durable. But I never dare put anything hot in it. I wait until it's lukewarm. Thanks again.

[@wwondertwin]

If you'd like to get brand new borosilicate Pyrex that's as good as the vintage, you should look into buying Pyrex made in France. All French made Pyrex is real borosilicate unlike the Pyrex manufactured and sold in the US. It's a bit pricier especially if imported to the US, but if you travel to Europe you can buy it for cheap as souvenir from any good shop that sells kitchenware. The French made Pyrex is the standard Pyrex all around Europe.

[@janetk3015]

@@wwondertwin thanks. I don’t know if i’ll get it. Knowing me i will mix up the two and they probably look the same 🤣

[@tripudium17]

Thanks for the video. I have seeing other brands in North America make borosilicate kitchen products. Now I understand the benefit of this material.

[@Aranimda]

Nice stuff. I got myself a borosilicate glass food container that is made for the freezer, microwave and oven. You can put food in, freeze it to -20 C and then put it into a preheated oven of 200 C without it breaking. Pretty amazing.

[@rn4l62]

Please note: PYREX is made of borosilicate, but pyrex is not.

[@tyronekim3506]

Thank you for the video. Years ago, I bought a PYREX bowl and measuring cup. Recently, I bought more but the price was less. I didn't know the difference between PYREX and pyrex. Now I know.

[@flbeachinggirl]

Pyrex stopped making Closed loop handles on their measuring cups. The newer open handle hooks on to pots in the sink and are a pain if they get caught on something while on the counter preparing food!

A few days ago I put some hot gravy in a Anchore Hocking measuring cup, i carried it to the table and put a fork in it to stir it and the cup blew up and threw glass over the hole kitchen. fortunately the glass was thrown more horizontally and did not hit me in the face. it broke in little pieces like safety glass.

[@suzannaflores1164]

[@TruthDigest]

Very easy, complete and nice explanation, thank you very much.

[@JS-ed2hg]

Very well done!!!! I remember being a child burning a flammable gel substance in a glass candle holder. Just being stupid as a child lol, I did it in the sink and to put it out turned on the water not even ice cold and then it exploded. Thank God I did not lose my eyes, before I knew nothing about thermal shock or other scientific findings. Great video you left nothing out!!!

[@ClearerThanMud]

Just stumbled onto your channel -- great stuff! Thanks for the tip about PYREX vs. pyrex. Anchor Hocking, which I think has never used borosilicate glass, claims that their tempering is 40% better about thermal shock than borosilicate. Are they lying?

[@GanondorfMaster]

Hey cool video man, helped me pass my exam :) one thing I think is wrong though is the addition of CaO into the silica structure, as it works as a stabilizer, connecting the non bridging oxygen atoms caused by Na2O rather than create NBOs. Great video man keep it up!

[@Azizm92]

Thank you 🤗 Borosilicate has been popular in Turkey thanks to the company that started doing/importing it long ago. They have created product range named BorCam (from Turkish bor - boron, cam - glass) but I wonder of they have switched nowadays to tempered soda-lime glass too

[@richragenj]

[@nicholasfrantz]

I heard a rumor that corning made borosilicate glass because of a roman legend where one maker who gathered raw materials near a boron rich environment, went to the ruler claiming to have unbreakable glass, and then was then killed on the spot because the fragility of glass creates value

[@BooBaddyBig]

Yeah, I wondered why the measuring jug with a pretty slightly blue tinge to it exploded all over the counter and floor when I poured boiling water into it when I was in Canada. Soda lime is junk.

Is borosil glass safer than limesoda glass to contain water or food

[@flbeachinggirl]

I am confused about car and home window glass. Im surprised it doesn’t shatter when we blast the heat on one side while ice, snow and water cover the other side.

[@LuisCaneSec]

That's because the change in temperature is gradual and not sudden. If you dump a bucket of boiling water on your cold windshield, you may get a crack.

[@MrVTeta]

@@LuisCaneSec Also boiling water adds additional thermal difference. Normal glass can handle thermal shock, what matters is how much.

[@techienate]

Borosilicate glass breaks into extremely sharp pieces when it does break, more than normal glass. Be careful not to touch broken borosilicate glass with your fingers

[@jujijiju6929]

[@Themsbeatlesrock]

How come borosilicate is more expensive to produce than soda lime? Is it because the materials to make it are not as abundant or the manufacturing process? Is there a chance it could ever become less expensive than soda lime?

It takes more energy to heat and produce

they should not be able to sell glass products as Pyrex if they are soda lime glass. the average consumer is not going to know that their Pyrex is no longer Pyrex

[@j7ndominica051]

Why does glass break more on cooling? Most glass can handle hot water/drinks poured into it. Even fairly thick glass. Then it breaks on touch and cooling. The difference between warm and cold beer is so small that the breakage must be a truly unique case. Quite a few common items need to withstand heat: water kettles, coffee presses, tea glasses, halogen oven, pan lids. They should make coffee presses with the diameter and height of a standard lab beaker so that it could be replaced. But pointless visual design rules, and they keep reinventing basic shapes.

[@HaveYouTriedGuillotines]

I really wish I could get new PYREX in non-metric. :/ I have two PYREX measuring cups, but the larger one has lasted so long that all the red text wore off, so it can't be used to measure anymore. I think this happened because the glass is legitimately more thermally resistant than the print, and decades of heating, cooling and washing wore the markings off. I want to replace it with an identical copy, but it's not possible because of greedy businessmen and their race to the bottom mentality.
