New studies find carcinogens in vg and pg at high temps, even in tootle puffers

I know have a Vamo for testing. (It was like an old friend when I opened the package, I smiled, it was my ADV for a long time)
First thing I will do is compare the same atty on both it and the provari at identical VV settings and see if I get the same temps. If I do then the Vamo will sufficient for future testing.

OK, how about some wicking tests? Thanks to @B2L for the cotton samples.
For the moment I am just going to number the samples, with #1 being on the left, and so on.
This is the separation rig which was placed over a glass jar:
- All samples were exactly 0.11g of fiber, except sample #5 which was so dense it wouldnt have been long enough.
- All samples were properly fluffed according to their type.
- All samples were placed in a 3mmID spring, akin to one of our coils.
- All samples were placed in a rig that kept them separated and also not touching the walls or anything else
- Jar was filled with a 50/50 mix of PG/VG with some pro grade food coloring
And the race is on.....
Im calling #3 the winner, and #5 the 2nd place contender just because of how much juice was trapped in the fiber.
Especially when viewed from above:
1-Koh Gen Do
2-VCC Vapers Choice (was probably the easiest to work with)
3-Rayon, big box from Sally's
4-Hemp
5-3mm braided Ekowool, considered the most premium silica
6- Native Wicks Platinum Blend
Now keep in mind that this is only HALF the story. With wicks we care about 2 things, capillary action, and flow. This only demonstrated capillary action. I am still pondering a good protocol to test flow.
Really though, from what I saw, anything but #4 and #5 would work just fine.
As promised, a follow up to the wick test. The first test was mainly to show how poor silica is compared to modern materials. The context being that poor silica performance might have significantly contributed to why Dr Kurt's Gen 2 results were so bad.
On this test I took the 4 best from the first round and matched them head to head.
Test Conditions:
- 50/50 PG/VG mix
- each wick trimmed to about 1.5 inches
- 0.11g of fiber each
- Coil (spring) was 3mm ID
- All set in a rig that kept them suspended without touching the walls.
- VCC Vapers Choice
- Rayon
- Native Wicks Platinum Blend
- Koh Gen Do organic cotton pads (outer skins removed)
Results:
- Initial Capillary
- Rayon
- Koh Gen Do
- Native Wicks (actually a very close 2nd IMHO)
- VCC Vapers Choice
- Capacity: (defined as g of fluid held in the wick after 1 hour))
- KGD - 3.22g
- Native Wicks - 2.69g
- VCC Vapers Choice - 2.13g
- Rayon - 1.72g
I am sticking with my rayon. Other factors like flavor, longevity, and scorch temp still make this my fave.

Thanks for the test Mike.
Rayon saturated the wick the fastest.
Cotton holds juice better. Rayon wicks faster.
IMO - Rayon won.
I want my wicks to feed my coils as fast as possible.

I agree for the way I build, but I can see where others might have other priorities. Lets say a guy with dual claptons that need a lot of juice, but he desnt hit often, maybe once an hour, the extra juice capacity held in the wick might be good for them.
I think for us tankers the transport ability of rayon is best but for the drippers holding more liquid is a big advantage. Again, vaping wins...whatever works for you!
You can run it just fine without all that stuff but whenever I get a new one I always set the internal resistance first w/ the little copper plug, then run case/battery analyzer.
Mike, you might be able to test flow by putting one end partially in something like the tank for the flash-e-whatever, leave the bottom end long and hang it out, upside down over a cup or something, then see how much drains into the cup over time.

I am out of most of the samples sent at this point. Probably dont intend to do any more wick testing. I think we know what we need to know for our individual vape styles. At least until some new "Game Changer" comes along.
For years I havent been able to get the archimedes screw out of my head.....
A miniaturized version of this, linked (closed loop control) to temp and/or wattage settings on the mod.
Thanks to @englishmick for donating the test victim!
Protank 2 users, you are in for a surprise!!!
These hits were all on a 2.2ohm stock coil between 5-6w. (Full detail to follow in a few hours)

OK, so the Protank 2 coils were a real PITA to test.
The 40gauge thermocouples are tiny, delicate, and they fell out easily and frequently. So I got a chance to see and feel the wicks a lot while re-threading the probe. There is no doubt, the rebuilt coils with cotton held magnitudes more juice than the stock coils with silica wicks.
This may shock some tootle folks, but data is data, and this is what I measured.
Stock 2.2 ohm coil on a Protank2. Red was 5.5w, yellow was 5.0w, and blue was 6.0w
*********************************
YES! - A stock 2.2ohm coil is measuring over 500f at only 6w! Just because you are "tootle" does NOT mean you are low temp!
*********************************
The rebuilt coil made with 30g kanthal and cotton wicks fared much better.
And finally, the full data:
Just for the record, NONE of these hits tasted burnt!
Properly rebuilt coils are pretty safe, stock silica coils are NOT, at least according to Wang and Geiss.
A good TC mod and you wouldnt even have to ask these questions......
