Even our Paleolithic hunters and gatherers must have been done an awful lot of gathering to get upwards of 100 grams of fiber a day.
VERY large quantities of kitchenware, serving bowls, ovenware, measuring pitchers, etc, as well as glass electrical insulators for telephone and power lines were made. A search of the internet, such as Google Images pages with “Pyrex insulator” and “CD 128” should bring up examples of that particular shape.

Each measures about 7 & 1/4th inches in diameter and 3 & 3/4ths inches in height. NOTE: In 1998, Corning discontinued the production of their PYREX line of glassware, (concentrating instead on their lines of tech-related products) and the rights to the PYREX brand name was assigned to World Kitchen, LLC. The most common Pyrex insulator (found in clear glass) would probably be the CD 128 style.The derivation of the word may be from magpie, shortened to pie.The explanation offered in favour or this is that the magpie collects a variety of things, and that it was an essential feature of early pies that they contained a variety of ingredients." ---The Oxford Companion to Food, Alan Davidson, 2nd edition, Tom Jaine editor [Oxford University Press: Oxford] 2006 (p.The Paleolithic period, the Stone Age, only goes back about two million years.
