May I suggest carbon steel instead? (I bought these ones specifically, because the handles are welded on, so there’s no rivet bumps inside the pan to collect crud) https://amzn.to/3OlGcXb

Are nonstick pans toxic”? “Can aluminium cookware cause dementia?” “Are my scratched pans still safe?” You’ve read the scary headlines now read the facts at @theconversationau

Excellent piece from Alex Tullo at C&EN detailing where different fluoropolymer companies are with backing away from or replacing #PFAS in their polymerization processes.
Unfortunate that #PTFE is one of the hardest polymers to find a non-fluorosurfactant replacement for

What’s the difference between PFAS, PFOS, PFOA, PTFE, and GenX?
"There are estimated to be more than 9,000 #PFAS chemicals. Some of the most common include Perfluorooctane Sulfonate (#PFOS) and Perfluorooctanoic Acid (#PFOA), also known as C8. These chemicals were once widely used in substances like fabric and leather coatings, household cleaning products, firefighting foams, and stain-resistant carpeting. Although manufacturers have phased out their use in Canada and the U.S. over the past two decades, they remain ubiquitous in the environment—and in our bodies. Dupont developed #GenX as a replacement for PFOA in 2009, but subsequent studies of GenX have also raised health concerns.
"Polytetrafluoroethylene (#PTFE), along with C8/#PFOA, were used to produce #Teflon, the non-stick chemical coating manufactured for decades by Dupont and now #Chemours, which #Dupont spun off in 2015."

Cycling while wet? Tech clothing option changes are afoot. https://www.cyclingnews.com/news/pfc-bans-are-going-to-change-the-face-of-all-waterproof-garments/
Personally I lean more towards layers involving wool. It's all about staying warm rather than attempting to stay dry while sweating in a rainstorm.

#PETG is stuck in #PTFE tube. A blob is forming at it's end. Even at the lower temperature given by the manufacturer (Sunlu) which is 220°...
I’ve successfully printed for hours at 235° I have no fucking clue on what’s going on. #Help please.
My guess would be that the speed/flow is too low, allowing the heat rise in the tube dispite the fan which is running at it’s max speed by the way.
