If it is the real Pedro Carvalho and he's a supplier here, why would that be an account opened today? Asking just out of pure curiosity and not trying to instigate anything.
Read the thread.
I already have. I was referring to Magaro's thoughts on Mr. Carvalho's message that Vwls just posted.
No clue, but if it is THE Pedro Carvalho and he posted anything here he would be immediately Moved On for not being a Registered Supplier here, so it's a catch 22.
Given that his reply to Vwls was just posted here, I'm gonna bet it's him.
That's true, but could a supplier not use their supplier account to read and watch other threads in the forum? I was under the impression you could only have 1 account here and it made me curious which is why I'm asking all of this, thanks for the answers.
Actually.
I believe that a Registered Supplier can post in a Thread like this. As long as He/She does NOT Post anything about their Business. Or Post Anything that could be Perceived as Promoting their Business.
But I could be Wrong.

I guess it could be a fake/imposter account, the timing just seems suspect.
Does Pedro still have a Supplier account here? I don't keep up with mechs at all.
Actually, all of them will undergo some of these changes, but let's move on.
Why do these oxides present a problem? Can you elaborate?
There's actually a pretty huge body of scientific data that documents the temperature of formation of hexavalent chromium for different alloys in different environments. Cr(VI) is a huge health concern so it's been studied to death (no pun intended).
A coil will glow red WAY before 900C, but whatever.
So let me get this straight: you are hypothesizing that eliquid is, for example, reacting with aluminum oxide at vaping temperatures to cause decomposition of the oxide? Do you have any proposed mechanism for how these simple low pH juices might be breaking down this extremely stable oxide?
So, if I understand correctly, we should basically try to prevent our coils from forming any oxide, or at least any oxide thick enough to provide corrosion protection? I think I'll pass on this advice.
That's why this whole thing made me curious and I really appreciate all your answers.
Is WHAT really necessary? I was simply pointing out that it could very likely be someone other than the Pedro Carvalho we have been discussing who created this account. And that they could be trolling this 31 page thread just to see what sort of response they can get.
I'm going to leave my comments as they stand for tonight. Here's hoping eventually everyone makes an informed decision on how they want to choose and treat their coils.

I assure you that the letter is from the real Pedro; he is a long time friend. The new account was him but it would not allow him to post (new member regulations) - this is why he asked me to post it for him. He is not a registered supplier on ECF and no longer has the account he had here years ago.
This is not my field so I might be totally wrong but my guess is that he's more concerned about the oxide layer starting to flake off (if thick enough) than with the oxidation by itself?
I remember seeing a Ti coil that had been continously pulse burned for some time (something one just shouldn't do) and it had a VERY thick layer of grey, dull titanium dioxide. I remember some pics showing the oxide flaking off rather easily.
This doesn't seem to happen with minimal thick oxide layers?
Just a guess...

Or, you know, maybe he's just reading this 31 page thread to try and get a sense of exactly what it is people are discussing.
This issue actually interests me enormously. Our ejuices are not that innocent--some flavorings, like cinnamon, citrus and banana, for example, are known to crack, fog up and even completely melt polycarbonate tanks. I can provide pictures upon request.
I have no idea what they can do to the stable oxide, if anything, especially at elevated temperatures, but it is most certainly worth investigating.

Not only that. Another issue is, really, how many casual and unsuspecting coil builders actually achieve proper oxidation of their coils? Watching some of those instructional videos that Dr. F mentioned in the interview, I'd guess very few...
