The Pyrex SS hybrid Wick

[stuntmunky]

I'd be in for the smaller stuff to give it a go.
I'd also be up for 3mm id stuff. I'd like to find thinner walls ideally. Might be worth waiting/following the ecf thread a while yet and see if a supplier is found for thinner wall quartz, with a group buy we could look internationally as well.
But if you want to go ahead Im in.

These any good to have a play with

Wondering if a porous ceramic material might be the answer? I was thinking about ceramic diffusers like you blow air through in an aquarium. Here's a US supplier, will have a look around for a UK company... www.sentrotech.com/porous-ceramics

I think you are spot on..A ceramic rod or tube with porosity between 25-40 microns should work well as a wick..

I know there is a device called the RES which uses ceramic as a reservoir for e-juice..Perps showed it me and I read up on it and it uses porous ceramic to hold e-juice.

I had an idea to use sinter rods but unfortunately they are quite fragile and not really suitable for making rods.

Hmmm..

Time to make some enquiries methinks...

Being a relative novice, I read threads like this & totally admire you guys.............Kudos........ #icon_welldone#

Are we talking about the ceramic being a capillary transport for the liquid or a porous design for heat penetration and still use ss mesh? If its capillary then we arent solving anything?

[maccafan]

To use it as a wick as a direct replacement for SS mesh.

By using a non conducting, non reacting glass based wick you get rid of the need to prepare the mesh, gets rid of shorting issues whilst still maintaining the ability to direct the airflow over the wick to get better flavour..Easy to slide in and out, make coil in situ and clean. All the best dripping attys out there house the coil in ceramic.

What does a pyrex tube over SS mesh solve exactly? Just coil gunk?

[Skwoddy]

From following the thread, the plusses were clean coils, no shorts, easily changeable mesh, and a ton of vapour. Negatives were condensation dripping onto coils, high wattage to power through the glass and difficult initial setup. Think its great that so many ideas are being put forward. Genesis may well win because of simplicity but rome wasnt built in a day. Ceramic works for me.

[maccafan]

I really think a porous ceramic rod/tube is worth a try..If it wicks well, it should be very good.

I not too sure how glowing coils on the outside of the pyrex/quartz glass tube will alter the taste, after having spent time learning to get rid of glowing coils because of the funky taste, and also the fact that it prevents air from flowing through the wick.

But won't know till we try both, I guess..

[Skwoddy]

The only reason the coils werent glowing as far as I can surmise, is that it was a 4 ohm coil, even with 15 watts going through it, totally dumbstruck when i seen it tbh.

as seen here:-
(also with a glass tank on a DUD GRRR)

[maccafan]

That's a 20mm x 2.5 mm thick pyrex tube and makes it look bulbous..

If anyone wants that tank, it's not a problem and I can get the manufacturer to supply that..

[Skwoddy]

nah im good, think the chid is gonna join the other one... in the bin, after ive abused it with ceramic and quartz.

Have been pondering this over the weekend - ceramic does indeed sound like a much better advance on SS than SS + glass tube.

I believe that some investigation into this is already underway somewhere on the ECF forums, it just hasn't attracted quite as much attention as the glass tube trick.

Think I'm going to hang tight for the time being and follow what's going on over there closely - people who went and ordered loads of quartz tubing as soon as they saw the original post will start receiving them this week and posting their results.

In the meantime may do a little trawl of the web to see what can be found in terms of porous ceramic rods. Unless of course Macca has already found all of them, verified the specs, made a computer model to find the optimum wicking porosity, negotiated a deal with a supplier and is awaiting samples.

I think the reason the quartz glass idea is getting so much attention is because it's clean. The idea of inhaling burnt fiberglass/silica/stainless steel, I think, bothers a lot of people.Does anyone here know about inhaling burnt ceramic. Isn't it quite a brittle material and therefore susceptible to chipping/flaking etc? Correct me if I'm wrong.

[maccafan]

Your coil would be long dead and pop before you can inhale burnt ceramic or stainless steel smoke.. .A shorting coil pops at 1350 degrees C if it is Kanthal A1 and lower for the rest and it is momentary. Burning of ceramic starts at 1700 degrees and melting point of stainless steel is around 1500 degrees.

You can't inhale burnt silica wick either at vaping coil temperatures. Normally a coil with a good wick is between 75-95 degrees C.
