LOVE your sig!

This much we can be sure of, UncleMidriff, it's not a natural material. Not cotton or wool. A synthetic, for sure. Most likely polyester. We all look forward to answers from manufacturers on the other thread. Meanwhile, if anyone can find a safe material that holds liquid, it will be Dr. Loi.

i think a fine grade stainless or titanium would would probably be pretty safe. neither should really leach. Aluminum, bronze, brass, and copper could all be problems.

My brother is a chemist, and while not 100% sure without testing, seemed to think those two metals would work well.

Thanks TB.....hope you don't put up too much expectation on me..There is at least 10 possible material to be used with a safer margin than polyester but all still need to undergo intense test and scrutiny...What Bro Dusty(I still can't bring myself to call him the Rat..hehehe :P ) has suggested was in the itinerary..but it doesn't hold back liquid well and seems to increase the heat faster than wool..there was some cartridge melting at the edges happens when the steel wool (inside the cartridge)overheats and during usage....

My suggestion to the manufacturers was a depot like liquid cartridges instead of polyester wool..I have a model like that..and I will post up the pics when I am ready to show how it looks like..future cartridges you can say...some of you will be familiar with it(..a hint..used in refillable ink pens )..later I will show you a sample(not a working model yet due to size problem)....

Anyway..FYI ..all burnt or heated up material which leads to carbon process will somehow be Carcinogenic..even our normal harmless bread if toasted till black or even BBQ meats all poses a RISK to all of us ..we live in a polluted world where there is a given 30 to 50 % of unseen carcinogens risk exposure..so... no excessive paranoia and fear needed here...just take precaution..As long as The Atomiser is kept clean and clear of any filter wool , you'll be fine....take my word for it....

THANK YOU doc.

I'll sleep better tonight.
It kinda has been a rough day today on the board, some scary stuff has been brought up, and after all it might not be so scary at all.

I had been under the impression that the atomizer worked by ultrasound, and not heat, although I guess when you make ultrasound it would probably be hard to do it without making some heat. Is this just marketing nonsense? Is it really just a little heater in there?

If you touch it, immediately after use, it doesn't seem hot at all...

There are NO ultrasound e-cig atomizers on the market. Everything being sold is a cheaped-down version from the original patent ideas. Vaporizing is done by heating an atomizer.

Here is a US patent for the e-cigarette cartridges. I didn't read the whole thing, but as far as I could see it was not very specific about the filling material. It just describes it as "Non Combustable".

If anyone can make more sense of it....

**TropicalBob** · 07-01-2008, 08:52 PM

That's an R.J. Reynolds vaporizing cigarette, using tobacco, I do believe. The original Ruyan patents are online, linked from some old thread. Some of us have read them and they did call for ultrasonic atomizers, an LED screen, all kinds of things that we don't have. Someone decided to dumb-down the e-cig -- and we got the dumbest of the dumb-down ideas in the present product generation. Expect an ultrasound atomizer and a six-speed automatic transmission in the new and improved 2010 model.

I'm wondering if there has been anymore discovered about the possible "dangers in the filter"? I just purchased my first e-cig from Totally Wicked. I have a super-mini with a bunch of Blank carts to fill with liquid. Is it dangerous to use these filters whereas they might be heating and vaping Polyester? I'm Vaping because I'm addicted to nicotine and feel vaping is a MUCH safer alternative.......I really hope I'm not vaping polyester.
