One of the things I have occasionally thought about is how the discoverer of turpentine actually did it. A scene plays out in my mind:
Bob: Hey Carl, how's it going?
Carl: Pretty good, Bob. What are you up to?
Bob: Well, I was about to go boil a tree.

Let's say you had a bunch of carbon tet hanging around (7 x 500 mL, unopened), would you hold onto it, just in case, or would you ship it off for disposal. Alternately, anyone want it?

How do you #label your #solvent squeeze-bottles?
I've recently taken to use carbon pencil + clear sticky tape / packing tape.
My prior ball-point pen labels tended to "dissolve" and smear out, over time, under the sticky tape.
Carbon pencil writing seems to be long-term STABLE - even on solvent bottles, with drips and fumes.
(here's a "funny": "we" Germans call it "Bleistift" [lead pencil], as in Pb - there's no lead in there! We all know it, well, the more educated do. Colloquialisms! 🤣)
Ever wonder why water can dissolve so many things? It's all about its polarity—a molecule with a slight + charge on one end & a - charge on the other. This makes water the ultimate #solvent, allowing life to thrive by transporting nutrients & clearing waste. 💧 Speaking of thriving, $PAWSY holders are living proof that chemistry applies to markets too—precision, balance, and a splash of innovation.

A trip down memory lane, when I was a young kid listening to the radio at night, those distant airwaves: "My Radio" by #Solvent .
"It doesn't seem so long ago
When I loved you, my radio.
You promised me so much, but now you've changed.
You always played my favorite songs ..."

Judge says far-right US news outlet filed bankruptcy in bad faith
A bankruptcy judge dismissed a bankruptcy case filed by the #Gateway #Pundit on Wednesday, saying the far-right outlet did not file the case in good faith.
The ruling from the US bankruptcy judge Mindy Mora in the southern district of Florida comes as the outlet faces significant #defamation #cases from two Georgia election workers and a former Dominion voting systems employee who say the site spread #false #claims about them after the 2020 election
Calling the site’s assets “eye-catching”, Mora noted that they were
22 times the size of its liabilities.
“TGP remains both balance sheet and cash flow #solvent.
There is no present financial distress, no looming foreclosure sale, no prospect of a market crash.
There is only the State Court Litigation in which TGP must defend itself.
That’s not a basis for bankruptcy relief; it’s the justice system in operation,” Mora wrote.
The Gateway Pundit declared bankruptcy on 24 April saying it was doing so as a litigation strategy in the defamation cases filed against it.
Filing for bankruptcy pauses all civil proceedings against a business.
“This is a common tool for reorganization and to consolidate litigation when attacks are coming from all sides.
It allows TGP to consolidate this lawfare in one court for ultimate resolution,” Jim Hoft, the site’s founder, wrote at the time.

‘Extremely toxic chemical’ found in many products may be banned by EPA. What is #TCE?
Brendan Rascius
Tue, October 24, 2023
"The Environmental Protection Agency (#EPA) proposed a ban on #trichloroethylene (TCE), a #cancer-causing chemical found in consumer and industrial products.
"The proposed near-total ban — part of the #Biden administration’s 'moonshot' initiative to eradicate cancer — would take effect next year, following a period for public comment, according to an Oct. 23 EPA news release.
"'The science is loud and clear on TCE,' EPA Deputy Administrator Janet McCabe said in the release. 'It is a dangerous toxic chemical and proposing to ban it will protect families, workers, and communities.'
"TCE is a colorless, liquid chemical compound that is manufactured primarily as a cleaning #solvent, according to the National Cancer Institute.
"It’s typically not found in products marketed to consumers, but among the household products it is used in are #CleaningPipes, #PaintRemovers, #Carpet Cleaners, #ToolCleaners, #SprayAdhesives and #BrakeCleaners, officials said.
"Industrially, it’s used to #degrease metal materials found in aircraft and as a refrigerant. It’s also employed in the manufacturing of battery separators found in #ElectricVehicles.
"The chemical compound is 'extremely toxic' and has been linked to adverse health effects, the EPA says.
"The agency has found that TCE causes #NonHodgkinsLymphoma and liver and kidney #cancer, officials said. It also damages the #ImmuneSystem, the central nervous system, reproductive organs and puts fetal development at risk.
"'These risks are present even at very small concentrations of TCE,' officials said.
"'TCE is also associated with Parkinson’s disease and possibly other neurodegenerative diseases,' Briana De Miranda, a professor specializing in toxicology at the University of Alabama at Birmingham, told McClatchy News.
"Exposure to the chemical can occur in a number of ways, the most common of which is via inhalation, De Miranda said.
"'If people work with TCE they may inhale it through its vapor phase or off gassing of the liquid,' De Miranda said. 'If people live or work where it contaminates the soil or ground water, they could inhale TCE via vapor intrusion into buildings.'
"It can also be ingested orally, including through #contaminated drinking water, and through the skin, though this is less common, De Miranda said.
"Exposure often occurs at #Superfund sites, which are swaths of land across the country that are designated as contaminated by the EPA. These include manufacturing centers, processing plants, #landfills and #mines."
