Heat temperature isnt necessarly the only factor when it comes to thermal shocking. It also depends on annealing. It only takes one bad batch of poorly annealed glass tubes to be bought up by one of us and literally have it blow up in our faces. One example I can think of is say your pv is in the car on a cold winter day. You come in the house and fire it up. So along with a bad batch of un annealed glass along with the extreme temperature change chances are you'd have extreme thermal shock.
I'm not saying this is not a great idea Dan. I'm just saying we should use quartz tubes. Here is my supplier I use to buy my quartz tubes.
Technical Glass Products: Fused Quartz Tubing
Bedazzle

Supplier and the stepped in here to try and lead us from injury. You would be go to for me when I needed to get more cut. Thanks for info and trying to keep tube out of our eyes!

Key word there is "relatively". It may work just fine. I'm going to buy some and give it a whirl.

From the chart on the site:

OD mm. ID mm.
....2.77.....0.51

I am assumig that the ID is the size of each hole. I wonder if the capillary action is enough to sustain wicking? If so this would be fantastic.

Problem I'm having is minimum order amount. I'm not spending $500 to experiment so I'll keep looking. I have found the single hole ceramic tubing in 12" length, so I may just try that.

Yeah, that is not feasible. If we knew it would work well, maybe a co-op. But there may be other suppliers with the four hole style, willing to sell samples.

I still think this could work in a ViVi, just a matter of making the tube short enough that it is shorter than the metal cup is wide. That way...

Well, now I'm not sure ... if we're using SS wick, would it end up over heating the juice in the tank or just allow vaporizing of the juice nearest the heat.

Exploration is needed with this ...

OK just tried this with an anodized piece of SS... Not going to work I don't think in a Vivi. First I couldn't wrap the coils tight enough to prevent shorts and second when it took forever to heat up any juice, and when I tired to see if it would draw couldn't get any Vapor at all... I am abandoning this idea in this type of device.

So the anodized coat held up? What was the wall thickness of the tube?

Here is another ceramic supplier Scientific Instrument Services. Seems a little steep pricewise (+15.00 for a six inch piece). And I'm not sure of a minimum order amount.

Edit: The only thing that bothers me here is in the description - "excellent insulating properties even at elevated temperatures". I'm sure that this doesn't mean directly applied to the wall, as the coil would be doing, but it would require actual testing to confirm.

Pete! Whats up :)

Ok straight capillary action vaporizing IMHO is out. I attempted 3 1mm pyrex tubes, no SS wicks:

The results:

Since there is no fiberous material to slow the juice down, the juice explodes out the end of the tubes. Vapor comes in cycles, when the evacuated juice leaves the tube, more juice creeps up and the cycle repeats. So there must be some form of wicks to hold the juice from rapidly expanding and pushing hot "lava" into ones mouth LOL. Very tasty though, once the taste buds heal LOL

That "excellent insulating properties" kills it for me. I was looking at porous ceramics a while ago and the only thing I could find was wicks used in a small insect repellant device. The diameter was too big so I stopped looking at it. My thinking at the time was that, if it wicked well enough, and could be made in the correct length and diameter, it would be the Holy Grail of wicks. I'm getting a headache!!!!
