It has properties that are not dissimilar to the original Pyrex, which is
borosilicate glass (still available as cookware in Europe, but it's not the
Pyrex sold for that purpose today in the US). "Gorilla glass" is
Anchor Hocking still makes & sells borosilicate glass products in the
US. A search on their site gives 442 hits so you're wrong, yet again.
Not since 1998, Michael. Read what I said above. Pyrex cookware sold in the
US today is tempered soda lime glass, and has been for over a decade. That's
why Anchor Hocking doesn't call their glass products "Pyrex."
Once again, in your desperate quest to prove your superiority, you've stuck
your foot in your mouth.
Check your facts, Michael. You should know better by now.
Both Michael and Ed are correct. Or very close to correct. I think
it was Corning Glass not Dow Corning that owned the tradename " Pyrex
". When Corning Glass was selling bakeware , Pyrex was borosilicate
glass. And Anchor Hocking was also selling borosilicate glass
bakeware. But Corning Glass sold the tradename to World Kitchens.
And World Kitchens now uses the tradename " Pyrex " to denote soda-
lime glass that has been tempered. Anchor Hocking is still selling
borosilicate glass bakeware. Naturally they do not call their
bakeware by another companies tradename, but you can buy bakeware that
is the same as the original Pyrex in the U.S. But you can't buy it
with the trade name Pyrex.
The borosilicate bakeware is better at not shattering because of
uneven heating or cooling. The tempered soda-lime glass may or may
not be better at not breaking when dropped.
You might want to look more closely at those 442 hits. Searching on
borosilicate alone yields 9 hits, searching on borosilicate glass yields
443, however examining them it appears that 434 of them do not contain
the world "borosilicate"--apparently the search is on "borosilicate OR
glass" rather than "borosilicate AND glass" or the phrase "borosilicate
I'm not "claiming" anything except that there are only nine items on the
Anchor Hocking web site that are specifically described on that site as
being made from borosilicate glass, and there appears to be no general
statement on that site that Anchor Hocking products are made from
borosilicate. If you can show that others currently for sale are also
made from it, please provide a list of products and SKU numbers (and,
ideally, links to photos of the labels showing the SKU number and the
"borosilicate glass" statement) so that others wanting borosilicate
glass can benefit from your experience.
Just to set the record straight, there are no Anchor Hocking cookware items
made of borosilicate glass. There are a few pieces of their stemware that
are, and some decorative canisters. But no cookware. All of their cookware
is made of tempered soda-lime glass, just like US-sold Pyrex.
As far as they know, there is no borosilicate glass cookware sold on the US
market. I have no way of checking that for accuracy.
Bodum sells some borosilicate measuring cups.
Saint Gobain Vidros sells Brazilian-made "Marinex" brand borosilicate
bakeware in the US if you can find it--Amazon.com lists quite a lot of
it. Note that they also have a line of tableware sold under the same
brand name that appears to be tempered soda-lime so read the details
Arcuisine in France sells a couple of sizes of borosilicate baking dish
on the US market--google "arcuisine elegance" and you should find a
number or sources.
The plot thickens. <g>
Last November, after we had our earlier discussion about this, after Iggy's
baking dish explosion, I had a lawyer friend look into the prospects for
importing Arc Pyrex into the US (importing cookware used to be one of my
parents' businesses, and I was interested.) Basically, he said "no way."
Pyrex is sewed up. To sell under another brand, you'd have to be prepared to
spend big bucks to build a brand.
My family having been in that business for years, but long before web
marketing, our experience was that marketing niche items in that market is
expensive business. There are several angles you can take but they're either
fiercely price competitive, at the low end, or they require some kind of
prestige cache, at the high end. My idea was that, if you could market
"original Pyrex," you'd have a natural. But it appears that the license
holders have it sewn up pretty tight. No surprise.
