Pyrex came along in 1908. Corning introduced it for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. Pyrex is a purely arbitrary word, devised as a trade-mark.
This glass is used in astronomy applications. Corning cast the mirror for the California Institute of Technology's Palomar Observatory project during the same time period. It took a year of cooling after it was cast.
It was the the shape of the measuring cup that my attention was focused on. It has remained the same for a long time. I have a measuring cup that is more than 50 years old. It looks like new, yet it seems that there would be better designs that are more accurate. It is hard to measure small amounts of liquid.
You can see one here at kickstarter.com. The design has 2,748 backers and has reached $129,159 of its $30,000 goal. The estimated delivery is May 2018.
The product information says: "We're tech nerds with a passion for cooking, and we've created a better measuring up. Euclid's patented shape delivers a level of accuracy that no traditional measuring cup can match."
What is that shape? It made me think of the pretty Calla lilies in today's pictures.
