Well, after four glorious hours of sleep (whoo hoo, how can I stand it, LOL)? The day begins again... O rfeels like it. Of coures, yesterday my brain fatigue hit and I forgot I had laundry in the dryer. Better than forgetting it in the washer! *whew*
Well, my furballs love my insomnia issues. I get up, they get up. Brushing, pets, play, oh boy!
Today's google doodle honors a German chemist who identified the compound we know and love as "caffeine", and also did many other things, but mainly, the doodle refers to the caffeine. He's probably notable for me for discovering aniline blue, a non-plant-based fabric dye, referred to originally as "a coal tar dye".
Why coal tar dye? The compound is a derivative --- or side effect, as you prefer --- of making "coke" from coal. A coke furnace was used to heat coal in a non-oxygen environment (or as little as possible), to get a high-carbon fuel. This is a method very well-known, and produces lumps of what kinda reminds you of pumice: Gray, porous, etc. Anyway, the "tar" residue?... Is useful.
Coal tar soaps/shampoos have been used to treat skin issues and scalp issues for well over 150 years. Meanwhile, the coal tar was processed with bleaching powder, and turned a gorgeous indigo-like blue. Since coal-to-coke production was growing rapidly in the 1800s? (To keep pace with coal-fueled steam engines, and coal-heated furnaces in such things as the iron and steel industry...)
Well, lots of coal "tar" to play with. So to speak. I've seen old coke furnace/kiln remnants. That's some nasty as heck stuff, IMHO. The furnace/kiln things were kinda beehive-shaped, and put off some noxious smoke and such, from what history records. Coke itself put off a lot less smoke/gas, as the coal impurities were burned off in the kiln. Since that meant coke was more carbon-pure than coal?
Basically, when the reaction ends? You get iron and gas when you use coke in smelting iron ore (especially hematite!). The gas is carbon dioxide. (Yep, good old CO2. Gives you the fizzies in your soda pop, and in the atmosphere it traps heat.)
Anyway, when you turn coal to coke, there's this nasty slag stuff, as I mentioned, and people finally realized this could be useful, and here we are. Coal tar being plentiful, then dyes derived from it were cheap(er), very bright, long-lasting, compared to th eprevious botanical dyes. (A few exceptions do exist.)
How di dI get here?
My furballs are tornadoes this morning. I've got to get sleep. I'm stressed. and a front is hitting... ooooh, achy!
OK, gotta referree the Taloned TErrors I call cats. Pum apaw-bump and happy Friday!
Today is my Birthday. This day had always been a special day for me. Thank you all for all for all the support you have given me through out the years i have been here. Thank you for getting me through tough times.Scott
Hey, all. No therapy today! And little sleep *again*. The weather went from "nromal" to "storm" to --- brace yourself --- 60*F by noon today. That's a lot in 72 hours for the old fibro barometer body!***The average age of a US citizen identifying as a "farmer" by occupation is 58 years old. The trend goes back to the 1980s, when farm foreclosures and other market force. Basically, farmers...
