I've seen all the pictures, videos, read every tutorial... The thing hates me, I tell you.
Besides, even when it works, it's not my favorite vape anymore. It's a bit on a warm side and the draw is too tight for my liking. So that ship has sailed. I've moved on to bigger and simpler builds, like my beloved kayfun 4. I know that many people hate it because it's over engineered, but I love mine. I've got two of them and they are absolutely delicious. Now I'm eagerly awaiting the promised release of the K5. I hope they simplified the design a bit.
don't commit yourself yet - there are some new developments
will fetch a link after supper ............
Thanks Tibs for your input!!!
I know a bit about ceramics; this new ceramic coils are sintered ceramic and they are also TC
I think/believe they are safe after studying them; also I always use fairly low power with my 40W. I have not ordered them yet. but i am pretty sure at this point I will, after waiting to see and study what you post.

Unlike the Aspire 'ceramic paper' issue.
'Sintering is the process of compacting and forming a solid mass of material by heat and/or pressure without melting it to the point of liquefaction'
From the PBusardo video, the sintering seems to make the material more like a 'cohesive solid' rather than the 'flaky shards of glass' of the old Aspire product.
So at 'first glance', it at least appears to be 'safer'.
What are ceramic coils? An introduction to Vaporesso Target 2 with cCELL coils
note; The ceramic coils HAVE COTTON INSIDE this dude below is wrong
note: I am not interested in Vaporesso other products, I like my iStick and Nautilus Mini's!
But they have very interesting state of the art high tech ceramic coils that work in in Aspire attys

There's (potential) trouble on the horizon. I don't have any facts yet, just what's being discussed right now. So you guys may want to wait for the final test results and/or join the conversation in VG's thread about cCell coils.
Oops, the quotes didn't make it--please see the post below...
Just read this comment by pbusardo concerning NI200, so thought I would post it:
"pbusardo 3 weeks ago
Safety Of NI200: Here's the problem. Until these materials... ALL the materials, both wire and wicking materials are tested properly and in the way we're using it's very hard for me to comment. How do I know that NI200 isn't 10x safer for me than using Kanthal? I don't know. How do I know that using Rayon soaked in man made chemicals isn't 10x safer for me than pure organic cotton? I don't know. And there's the problem. We don't know, but we need to know. And soon. This is why I'm really pushing Dr. Farsalinos to do the materials test. WE NEED TO KNOW. What I won't do is create a scare or concern in the market without having the scientific data to back it. A couple other things I can mention. I know of at least one person who has a strong nickel allergy who has been using the tech without issue. I'm sure that by now, we would have heard more from the community is NI allergies were causing an issue. Also, keep in mind that nichrome was pretty much the first material that was used in early atomizers again without issue. I'm not trying to justify or defend the use of NI200, but I am saying we need real studies before blowing the whistle. Same goes for titanium, which you're going to start hearing about more and more very soon. But you have my word, that when the study is done, and if the results are bad, I'll be the first one to post that information for people to make an educated decision on how these choose to vape. -Phil Busardo From Dr. Farsalinos: Hello Phil, As i have said, problems can occur only if Nickel (or other metals) are emitted to the aerosol and at what levels. We currently do not know. Nickel and chromium are carcinogenic but without knowing at what levels they are emitted to the aerosol we cannot say of they are safe or not. From Evolv: Nickel Carbonyl is created in the refining process and you'd need temperatures around 3,000 degrees Fahrenheit to generate Carbonyl. Hi, Off the back of your announcement today of the new DNA 40 board and it's ability to control the temperature of a nickel coil, there has been much concern on vaping forums about the use of nickel wire as a coil. Here is an exert of some of the comments: "Bad, bad idea. Look up the toxicology of nickel and ask if you want to heat that and inhale the result. I won't. " "Nickel is relatively chemically unreactive to some things, but not to others. It reacts very rapidly with carbon monoxide. And nickelcarbonyl is really evil crap. And heating any organic flavour is going to resul in some carbon monoxide production. " "So in your opinion using nickel or nichrome as heating wire for vaping is dangerous? I don't know enough about it to judge if you're right or wrong. I hope you're wrong because I think this about to be the next big thing in vaping. This technology is going to start popping up in mass market devices very soon and some premade atties are going to come with nickel rather than nichrome. " Are you able to allay any of these concerns over using nickel wire? Is there a specific type or grade of nickel we use? Does nickel wire pose any more harm than Kanthal A1? Kind regards Our response: We agree Nickel Carbonyl is truly evil crap. Fortunately, there isn't any here. Point 1: We aren't generating carbon monoxide. The whole point of temperature protection is to, well, protect from elevated temperatures. Heating doesn't generate carbon monoxide. You have to be getting combustion or pyrolysis. And you have to be combusting in a fuel-rich (less oxygen that stoichiometric) environment. Like a cigarette. We never get anywhere near combustion temperature, and even if we did (say, one turned the temperature limit up to 2000 degrees) the environment in an atomizer is oxygen rich, not fuel rich. So you would get carbon dioxide, not monoxide. To get pyrolytic decomposition of the fluid into carbon monoxide and hydrogen, we would want a coil temperature of about 1500F and you'd need to have it sealed off from air completely. Point 2: If this was a problem, we would have already seen it. The Mond process you describe (nickel ore to nickel carbonyl to nickel metal) is how one refines nickel from ore. The commercial coils are already 80% nickel and run at higher temperatures when they dry out. If we were getting nickel carbonyl production, that would refine the nickel out and we would end up with a porous wire with only 20% chromium left. That's not what happens. Point 3: Given that all the real research, vapor analysis and long term studies that have been done to this point have been done with commercial cigalikes, all of which use Nichrome coils (80% nickel and not at all protected from overheating) if there was a substance as toxic as nickel carbonyl in the vapor, the anti-ecig forces would be screaming that from every rooftop. Nobody has found any, even in devices that aren't temperature controlled. One study did find some metallic nickel and metallic chromium from pitting in the vapor steam, so they were obviously looking for metallic compounds. I'm attaching the Goniewicz research paper which is one often cited by those on both sides of the e-cigarette safety debate. The study looked at products using nichrome heating coils. And yes, they measured nickel. The study also looked for carbon monoxide in the vapor stream and found none. Zero. The following excerpt is from the study: "The amounts of toxic metals and aldehydes in e-cigarettes are trace amounts and are comparable with amounts contained in an examined therapeutic product." Dr. Michael Siegel said of the Goniewicz paper: "The most important finding in this study (that the authors failed to acknowledge) was that all of the trace levels of metals they found in e-cigarette aerosol were within permissible exposure limits for FDA approved inhalable drugs and devices (e.g. nicotine inhaler, asthma inhalers) per Pharmacopeial Convention." Basically it boils down to anything a Nickel 200 coil would do, a nichrome coil would already be doing (and worse due to higher temperatures) and nichrome coils are the only ones that have been studied in any meaningful detail by the real scientists, labs and MDs. What Kanthal is or is not doing, we cannot say as we haven't really studied it. What is a problem with the commercially available nickel 200 wire is they use a particularly nasty tasting oil in the drawing process. So if you roll a new coil without degreasing the wire first, you initially get a nasty taste from that oil. A good washing with acetone or simple green, followed by rinsing in water, solves that problem. But that is something to point out if people are reporting weird chemical tastes when they first try it."
I hadn't heard of a party, but if you're throwing, I'll be there.
It's not definite yet. But I'm on standby for La Mirada in February. Of course, I'll have free time. I certainly can't be near the coast and not watch the sun set. I've always liked Long Beach. I hear there are some cool vapers in that neck of the woods too.
Long Beach is a bit outside of my comfort zone, but I used to like the E-cig City in Laguna beach. Many ECF members used to go there in the old days. I haven't been there in a while though.

Personally I think the whole Aspire 'ceramic paper' issue was bogus!
But that is another story.
But these coils might be a vaping game changer?
Sintering ALSO makes ceramic coils porous and with the added organic cotton improves wicking THROUGH THE COIL, not to mention makes excellent sintered ceramic filtration of the juice, it's a win win win in high tech coils/atomizers vaping technology
sintered filtration is simply excellent down to a few microns!!! Its used a lot in chemical glassware filters

Do we know what this sintering process does to the wires? Heating them for a prolonged period up to 1,200 degrees centigrade?

If this trip materializes, I'll be in Laguna, with no doubt. I have friends there and I've never been.
I don't. But that's all over now.
However, they did have those tiny, respirable fiberglass particles (under 5µ) that you really, really don't want in your lungs--they cause silicosis. (Chart made by Boden to show the size of amorphous silica fiber used in silica rope (22-32µ)--the safe kind--in comparison to the unsafe crystalline silica fibers).
Water under the bridge.
Moving on.
Carry on.
