I wanted to do a post about this but soon learned that things get very chemical very quickly. Those two links up above will get you started, if you want to look more deeply into this modern wonder.
Or you can simply sit back and enjoy a short silent movie of someone at Tuffnell Glass fashioning borosilicate glass into something not at all utilitarian – a dragonfly!
For the first time ever, I recently tried a French press for making coffee and like it a lot, but the glass is SO thin.
Since I’m old enough to remember when you had to put a metal contraption underneath Pyrex so it wouldn’t break when you used it, I was really careful about pouring hot water into this at first.
Of course, it’s fine. According to Dr. Wikipedia, this borosilicate glass has an extremely high resistance to thermal shock.

After getting an associate's degree in forestry, I studied geology as an undergraduate back in the 1980s but went into medical transcription instead. It just worked out better for me.
The Internet renewed my interest in geoscience as a hobby, and when I retired in 2014, I decided to write a book about cat evolution. That started a new career for me (enormous fun but not self-supporting yet).
Right now, besides blogging I am finishing up the first two books in a self-published ebook series about the cat family and its history.
Thanks for your interest!
