Health hazards[edit]
Fibrous dust[edit]
Based on the total experience with humans and the findings of scientific research (animals, cells), it can be concluded that elongated dust particles of every type have in principle the potential to cause the development of tumours providing they are sufficiently long, thin and biopersistent. According to scientific findings inorganic fibre dust particles with a length-to-diameter ratio exceeding 3:1, a length longer than 5 μm (0.005 mm) and a diameter smaller than 3 μm (WHO-Fibres) are considered health-critical.

HTIW processed to products contain fibres with different diameters and lengths. During handling of HTIW products, fibrous dusts can be emitted. These can include fibres complying with the WHO definition. The amount depends on how the material is handled. High concentrations are usually found during removal of after-use HTIW and also during mechanical finishing activities and in the assembly of modules. Where fibre products are mechanically abraded by sawing, sanding, routing or other machining the airborne fibre concentrations will be high if uncontrolled. Dust release is further modified by the intensity of energy applied to the product, the surface area to which the energy is applied, and the type, quantity and dimensions of materials being handled or processed. Dispersion or dilution of dust produced depends on the extent of confinement of the sources and the work area, as well as the presence and effectiveness of exhaust ventilation.

Crystalline silica[edit]
Amorphous HTIW (AES and ASW) are produced from a molten glass stream which is aerosolised by a jet of high pressure air or by letting the stream impinge onto spinning wheels. The droplets are drawn into fibres; the mass of both fibres and remaining droplets cool very rapidly so that no crystalline phases may form.

When amorphous HTIW are installed and used in high temperature applications such as industrial furnaces, at least one face may be exposed to conditions causing the fibres to partially devitrify. Depending on the chemical composition of the glassy fibre and the time and temperature to which the materials are exposed, different stable crystalline phases may form.

In after-use HTIW crystalline silica crystals are embedded in a matrix composed of other crystals and glasses. Experimental results on the biological activity of after-use HTIW have not demonstrated any hazardous activity that could be related to any form of silica they may contain.

I dont think its a issue. I also use Ready Wick. I used to smoke cigs and drink allot, I wasnt worried about that at the time. Im not worried about vaping either.

 

[JustMeB]

My thinking is as long as you're not handling the product, and it is saturated it wouldn't produce these dust particles? Somewhat the same as dusting with a dry cloth vs. dusting with a damp one? (Dry kicks the dust up, damp traps the dust in).

I really like the coil videos that's really a great view of the whole coil.

 

[Akasticker]

From my understand this is some type of ceramic fiber, not fiber glass. they are both fibers perhaps though? Idk about you guys but after switching from kanger style silica wicks and silica in RDAS to BVCS ive never felt better. Honestly since switching to BVCs i no longer get any type of vapors tongue or and harsh throat hits. I think they are great and unless anyone can actually come out and say that these are in fact actual fiberglass and that vaporizing off saturated fiberglass is bad for you then im gonna keep using them and enjoying them as i have been. Just because one guy took it apart and it crumbled doesnt mean that its bad for you either. The material is also not being vaped dry. Perhaps vaping dried out ceramic fiber is bad but so is doing the same with cotton. But we keep them saturated with juice so its not an issue. Also as a side note i do believe the mesh screen is to somehow prevent spitback not pieces of the filler.

 

[Heavyrocker]

Ceramic is the cleanest vaping material.

 

[drunkenbatman]

Hey OP! All of these points and better information on what the filler most likely is, why it's a bad thing is in this thread for you to make up your own mind.

http://www.e-cigarette-forum.com/fo...ficial-statement-atlantis-coils-material.html

In my mind they're a dark cruel joke by a 4-year old chinese company that's made its priorities clear, and they aren't you. They've been asked point blank multiple times how it differs from the known ceramic fiber paper on the market that are known not to be safe for inhalation (inflammation, carcinogen & long-term permanent damage) and dodged the question while saying they'd switch to cotton. It's not like you're going to sue them in China, and while it may take awhile for the damage to show up, and long-term use for it to get really bad, there's zero reason to think it isn't happening.

 

[Katya]

Err... if you use a ceramic cup to vape out of, perhaps.

But ceramic/fiberglass paper contains crystalline silica fibers, which are really a big no-no when it comes to inhalation. Wet or dry.

Please read the thread that Drunkenbatman linked above if you need more information, documentation and science wrt crystalline silica and inhalation (thinks cancer and silicosis).

Why quit smoking and drinking then?

And cotton lung disease is real and very bad for you. Most people think that cotton wick is safer. It's no more safe than any other wicking material.

Nah, rayon's the safest, because...



that's what I choose for wick.

Whatever keeps us off cigarettes is the safest alternative. But chances are there is no truly "safe" wicking material in reality.

Cotton lung disease (brown lung, or byssinosis) doesn't apply in using it as a simple wicking material in an atomizer. You're not correct here, and it's discussed as to why in detail here after someone else claimed it caused cancer:

I have to respectfully disagree on both points, simply due to the science behind the materials. Here's two links where from the thread above where it's discussed in more detail:

It could well come up at some point that normal silica isn't safe, but we have no reason to think it isn't safe right now based on our current understanding of biology and materials. Conversely, there is no reason to think the material in a BVC coil isn't doing damage that can't be reversed. It doesn't matter that you don't notice it now, because that isn't how damage like this works.

So the test report labels the wick or filler material as "fiberglass".

Is ceramic and fiberglass the same material?

That I know of - anything involving glass is some variety of silicon and possibly other added ingredients, there is a disease called; silicosis, but I think that involves inhaling very fine silicon fibres. Not sure - but I think asbestos is some form of silicate.

The only ceramic I can think of that I actually know what its made of, is spark plug insulators - that's alumina, or aluminium oxide, its commonly used for abrasives or sintered into grinding wheels.

 

[350ZMO]

Fiberglass is a type of fiber reinforced plastic where the reinforcement fiber is specifically glass fiber.

The glass fiber is made primarily of SiO2 but it contains some percentage of other oxides that modify its properties for a particular application.
Common fiberglass modifiers are calcium oxide (CaO), magnesium oxide (MgO), aluminum oxide (Al2O3) and boric oxide (B2O3). Applications like insulation or making a boat.

Silica is SiO2 and is glass.

Reputable silica wick (rope and woven tube and sheet - paper and matting and flat stock) including readywick is literally made of glass or fiber glass. Woven fibers of SiO2. Not exactly fiberglass that we think of that has other stuff in it.

Still, I believe microscopic silica glass fiber javelins imbedded in my lungs pose a health hazard even though there is no proof as yet.

I always laugh when I see terms like "ceramic", "wool", "bio", "eco", and etc used when talking about silica wick.

This is a ceramic wick:


This is 99.9% silica wick:


This is fiberglass insulation:

The most commonly produced fibreglass these days is from recycled glass - they melt the glass and spin it just like candyfloss (cotton candy).

I haven't the faintest idea what elements are added to colour glass bottles, but lead is a common ingredient in cut glass tableware and sometimes uranium is used to colour glass ornaments

 

[caramel]

Is there any disposable atomizer that would work great around the 8W mark and uses cotton exclusively?

There are different kinds of silica; one kind is OK for vaping--and it's been discussed on this forum for quite some time, long before Aspire introduced their fiberglass/ceramic wicking material. Amorphous silica, commonly used in wicks by all (or most) e-cig manufacturers, has been deemed safe by our resident chemists and is even approved by FDA for use in food and medicine. Those tiny wicks threaded through the heating coil, used in cartomizers, atomizers and clearomizers, are all made out of amorphous silica. Kanger's OCC (organic cotton coils) made for the Sub Tank do not contain any silica fibers because they use Japanese organic cotton (see picture of Kanger's coil I posted earlier).

Please read this post by tenshi, and this one by Boden,and [URL="http://www.e-cigarette-forum.com/forum/health-safety-vaping/377764-dangers-silica-wicks-5.html#post9181477"]this one by Kurt,[/URL]our resident chemist and a person I trust completely in all matters related to chemistry.

More on the subject:

http://srs.unm.edu/industrial-hygiene/media/docs/silica.pdf

"Amorphous Silica: Multiple studies have found amorphous silica to be biologically inert when
ingested and inhaled, with the exception of extruded fiberglass and ceramic fibers (which have been
designated as carcinogens by the National Toxicology Program), which are hazardous due to their
very small size and their high length to width aspect ratio. Because of this inertness, the US Food
and Drug Administration permits the use of amorphous silica (not fiberglass or ceramic fibers!) in food
and medicine. "

So, the question under discussion is not whether Aspire is using silica fibers or not, but what kind of silica they are using, exactly. Their lab test clearly states that the material tested is fiberglass. And fiberglass (crystalline silica) is not suitable for inhalation.
