The end of microcoils?

My internet's too slow. I can't load the most recent statement right now. What does it say?!
It just seems like One Day things are Dire. And of Extreme Importance.
And a few Days Later, things are OK. And "No worse than Smoking".

This sounds cool, but it's not really happening. At 500F the THEORETICAL (extrapolated from near the melting point, which is about the only place it can even be measured for solid nickel) vapor pressure of nickel is something like 1x10^-34 atmospheres. Which is something like one atom per billion cubic meters of space. There aren't nickel atoms (or iron or chromium or even aluminum) jumping out of your coils, folks. That is, unless you're melting them while you wait for them to glow.
Anyway, not while you're vaping. Especially if you dry burn them first and seal the surface with a nice protective oxide. Does some of the oxide flake off? Well, that's another matter. Possibly, occasionally. But then it's at least an oxide, which the literature suggests has far less health risk than the elemental metal. And there's no credible evidence than any significant number of these particles are the dreaded nanoparticles everyone seems to fear so much.I'm retiring to my lair for awhile to dry burn a couple of Kanthal Claptons, rewick them, and vape an excellent NET while sipping a fine tequila on the rocks. Cheers.
You are absolutely RIGHT! The vapor pressure of solids such as nickel is EXTREMELY small. That's the point. I'm going to do the same as you although I'll be choosing Scotch!This sounds cool, but it's not really happening.

Good article that touches a bit on tootle puffing vs cloud chasing as well as the original topic of dry burning and metal inhalation.
Now I should not be polite. Enough.
So-called "a material sciences expert" knows nothing not just about metals but about chemistry in general (as well as Dr. F). Bullmanure about "molecular structure and integrity of the metal" is repeated again. It is such a nonsense for metallurgist, chemist and a bit educated in sciences person! I stopped reading the blog immediately. I though better about Dr. F...
EDIT: in most cases it is much better to acknowledge mistake than try to hide it.

And these calculations assume a perfectly cleaved sample in vacuum, thus it ignores the ever-present real-world oxide film of any metal or metal alloy we even care about.
Air do shlàinte, dude!
What concerns me is how the big time youtubers will respond to this issue, if it comes to their attention. This misinformation can propagate quickly. And THEN it gets to the people who oppose vaping. And we all KNOW how they'll use it.

"How much is metal exposure elevated by dry-burning the coils? Probably not very much. That is why we think the vapers have over-reacted to my statement on RY4radio. "
Probably. Not very much.
Maybe we wouldn't have over-reacted if he had initially said, I'm guessing this may happen but if it does, probably not very much.
He could have come back in his blog and said, sorry I walked into your party and dropped that big metal ball with the burning fuse sticking out the side. I didn't mean to scare you.
On the other hand Dr F has made us think about coils, which I've never given much thought to before.
I YouTube, albeit far from big time. My channel is not driven by the need to put stuff over because I feel obligated, rather, I aim to help people get the same rockstar vape that I do.
Funny stuff, I wound, named and published the first "micro coil" here on ECF about 2 years ago. I called it a micro coil because it was small in diameter. This was when tech for coil making involved hand winding around something. For the first micro, I used a picture nail. The wraps were erratic and not in contact, but they looked real close under normal viewing conditions. It vaped much better than the standard 1/8" dia 4 wind coil that was popular back then. Then the YouTube celebs started to make videos about "micro coils" being all about touching wraps. I believe it was Grimm green that made the first "micro coil" video. I got no props and he made anything but a micro coil
. That was about 6 months before I started to make my own vids.
As tech evolved, making contact micro coils became easy.
I just had to drop that here as this is the first micro coil ever made public
It started as a thread in the REOsmods forum then the HUGE thread in the then "Rebuildable Atomizer" forum.
Some YouTube celebs have misled so many, and I'm sure they mislead many more.

I'm sure Dr Farsalino made the statement with the best of intentions but unfortunately I believe he both failed to understand the issue AND failed to understand the potential of his statment on coils to undermine the life saving potential of vaping to help folks stop smoking. Now, no doubt, he's concerned about his "reputation". The best thing he could do for his reputation in my opinion is to go back, restate, based on fact, and apologize for not clearly stating fact in his comments in the first place. I hope his credibility in areas where he publishes scientific data and valid conclusions is not harmed by what I believe was a serious error of judgement. I also hope he doesn't decide to hold it against the vaping community for "calling him out" on this. There seemed to be a slight hint of that when he suggested that the community was overreacting to his comments. We need him, and folks like him to publish the truth about vaping and no ones ego should get in the way of that.
I think about them a lot. I just never thought about how dry burning was breaking down their "molecular structure".
Those of us who played with titanium before TC existed have given it at least some thought. I don't dry burn titanium; I sorta steam-clean it. I do still dry-burn Kanthal though.

Props and respect from an enthusiastic follower. YOU and your channel introduced me to squonking. Many thanks.
