Making the 200‑inch, 20‑ton mirror involved melting mountains of quartz in a giant furnace heated to 2,700 degrees Fahrenheit, writes David O. Woodbury in The Glass Giant of Palomar.

Quartz minerals in Earth’s crust are thought to melt at high temperatures. Laboratory friction experiments, however, show that metastable melting of quartz on a fault surface can occur at lower ...

I’m melting! The researchers divide the ensuing events into three phases. ... That's enough to shock-melt quartz, even if said quartz weren't already being heated by radiation.

"Melting Sun II: Cherry Quartz" was inspired by a cherry-tree alley in the woods near my house. I used to go to there with my dog in the summertime.

"The quartz crystal is neither a solid nor a liquid. Its vibrates (sic) a 786,000 pulses per millisecond! ... "Its melting temperature is over 1,600 degrees Celsius." ...

Researchers in Japan have reportedly invented the ultimate summer treat: ice cream popsicles that don't melt. As Quartz reports, scientists from the Biotherapy Development Research Center Co. in ...

Glacial melting, scientists agree, ... near the Swiss glacier have used the blankets every summer for the last eight years, Zoë Schlanger reports for Quartz.
