An article about how in the GDR a state-owned firm developed a damn-near unbreakable glass. Of course as with most other industries in the GDR, the plant got bought out by western interests and stripped for parts. We’re told it’s because “socialism is inefficient” but this is a good example of how that’s bullshit - the commies made something of such high quality it was deemed “unmarketable” because retailers wouldn’t have more repeat purchases of people who broke their glasses. Not even because they were too expensive! As the article states these glasses were ubiquitous across the GDR.

The article is mostly free a brainworms except one odd digression where the author states that no one knew who the glass designers were because in the GDR they valued the collective over the contributions of the individual. Hey, without Googling, can you tell me who came up with idea for Yeti mugs? Or the Stanley cups? Just a weird point to make, like in any society people have any clue who is designing fucking drinkware.

The actual science bit:

Glass Structure Research at the Central Institute for Inorganic Chemistry near Dresden. The material scientists there knew that when glass breaks, it is typically due to microscopic cracks in the material’s surface which form during the production process. Dramatically increasing the toughness of the glass surface was possible, they found, by replacing the smaller sodium ions in the glass with electronically charged potassium ions. Potassium ions need more space, pressing harder against neighbouring atoms and building up more tension that needs to be overcome for the microscopic cracks to get bigger.
