Turning Quartz into Lab Glass

791107316311190565

If you work in a lab, you’ve probably used lab glass made from quartz. But you probably haven’t realized that the reason those test tubes are so durable is exactly what makes them so hard to mold.

This bespoke lab glass can withstand insane temperatures and chemical reactions because it’s made of fused quartz. That means it contains virtually none of the stuff that’s added to normal glass to make it easier to mold at lower temperatures.

Instead, this stuff is virtually pure silica, aka quartz crystals—which means that to mold it into test tubes, you need incredibly high temperatures.

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
