Potassium carbonate is derived from wood ashes by mixing it with water, letting it soak for a while to dissolve it, then filtering out the ashes and evaporating the water. The potassium can be used to create soap by saponifying oils and fats. This is also why wood ashes can be bad for animals to play or roll in, and can be bad for the soil if it's simply poured in one place

His dead what?
Print out a grid and use that to determine how the lens warps the image (e.g. barrel distortion)
The point was that rich people (capitalists) play with the lives of others for entertainment and wealth (e.g. gambling, stocks, company margins), and dont care of they get hurt or die. Squid game takes it very literally by kidnapping and trapping people, and putting them into death games that the rich can watch and bet on. It isnt much different than the rich trapping us in low wage jobs while we slave away and die from a lack of health care while wall street ghouls bet on stocks. This is in why there is so much support for Luigi Mangione - people are tired of being exploited.
Some people believe that they can push through and become one of the rich guys in the end, but reaching that point requires the same exploitation of others that keeps the rich, rich. So rather than saying its better than capitalism, its saying that it IS capitalism. Its a critique of capitalism: "Either you get exploited or you exploit others"
Theres a lot of things which used to be part of american culture but have fallen out of fashion for one reason or another. For example, a lot of american christmas songs reference roasting chestnuts, which most americans have probably never seen in their lives because an infection brought over from japan on imported plants wiped out almost all of the chestnut trees, the dominant tree in the eastern US. Id say with the 12 days of Christmas its because of capitalism and endless work leading up to christmas and right back to work afterwards.
Ceramics arent unheard of in terms of pcbs and ic packaging, though forest clay certainly isnt the ideal ceramic by any means. Ceramics also are much harder to work with and create things like vias. They are sometimes used in interposers or for creating interconnects in chiplet designs due to their capacity for high density microvias
The amount of plastic waste we generate is ridiculous. Walking into a store at the mall, theres walls, racks and containers of crappy toys, stickers and knicknacks that only an old person, who isnt familiar with what theyre kids like, would buy. As far as i could tell, at least 60% of it would probably end up being burned or landfilled without ever being sold to a consumer. Who is going to buy a shitty little rubber generic controller keychain? Or 5000 funko pops. Or a 600$ gameboy game
