That Borosil bowl you use every day, the one that goes from freezer to microwave without a fuss, is made of the same glass used in pharmaceutical research, space shuttles and nuclear waste storage! It's not a marketing exaggeration. It's just chemistry.
Borosil's glassware is made from borosilicate glass, a material that doesn't expand or crack the way regular glass does when it hits sudden heat or cold. That's why your bowl survives the microwave one minute and the fridge the next, while a regular glass container would eventually crack under that stress. This same property is exactly why borosilicate glass is used in research labs for beakers and flasks, in astronomical telescopes, in thermal tiles that protect space shuttles during re-entry, and even in containers built to hold nuclear waste, as claimed on the Borosil website.
Borosil has been making this kind of heatproof glass in India since 1962. For most of us, that's just meant reliable kitchenware, but there's a bigger story, let's say, chemistry behind it.

X user Piramal shared an interesting story about Borosil's innovation, and wrote:
In 2010, long before "Atmanirbhar Bharat" became a mainstream tech narrative, India imported 100% of its solar glass, primarily from China. Solar glass is not standard window glass. It requires extremely low iron content so light passes straight through to the PV cells w/o reflecting away precious energy. The Kheruka family decided to solve a fundamental physics problem in materials science: How do you make solar glass thinner w/o making it fragile?
Borosil's team spent years working on this at their plant in Bharuch, Gujarat, and eventually built the world's first fully tempered 2mm solar glass, thinner than the standard 3.2mm or 4mm sheets, but still tough enough to handle hailstorms and extreme weather.

This cut panel weight by over 30% and even improved how much sunlight the cells could absorb. They also removed toxic antimony from the formula, making the glass fully recyclable, something European manufacturers took years to catch up on.
So the same low-expansion, high-purity glass chemistry that keeps your dal from cracking your storage box is quietly powering India's solar energy push and sitting in research labs across the country.
It's incredible for something you probably just use to store and reheat leftovers.
