Something to ponder.
My younger sister still has a Pyrex measuring cup that our grandmother used which is virtually identical to one you can buy today I have no Idea how many years our grandmother used the cup She passed away in 1965 when I was just 11 years old but I remember her making cookies cakes pies she made the best pies I've ever tasted and the measuring cup was ever present.
So my question would be were the cups made by the same or similar machines some 50,60 or more years ago? I've often thought of the generation just prior to mine as having been the smartest generation. They came up with ways for repetitive duplication while later generations have only managed to convert to more automated higher speed machines mostly based on ideas and machines from bygone eras
Just as a reminder, OLD "Pyrex" was borosilicate glass. They sold off the consumer products division so "Pyrex" just became a brand name for "stuff". The glass-like items are just soda glass now.
However, the laboratory "Pyrex" stuff is still borosilicate.
It's like how mecurochrome was banned for having evil toxins. So, now you can buy a brand of wound treatment called Mecurochrome(tm) that is essentially the same as Bactine with food coloring added.
When my youngest graduated from College I gave her 3 crates of various sized beakers test tubes a 5 tube centrifuge and a box of valves some lengths of tubing and a Bunsen. She said dad I'm going to be teaching the 2nd grade not high school. chemistry. Well you can always set the stuff up at home and create the world's most elaborate coffee maker. She still laughs about that 20 years later
