The Pyrex SS hybrid Wick

[mre777]

The glass is darkining from the juice. If no juice were in the tube the color would not change. The inside of the tube where the coil is is where the highest temp it, and the juice is building up crude where the pyrex is hotest. It is not because of lead in the pyrex IMHO.

I agree Dan that there is no lead in the Pyrex, but i think he was using a glass fuse. I had a neighbor who did neon signs and he mentioned the lead in the glass thing to me some years back. Some types of glass have lead and when heated the molecules un-aline they take on a smoked shine inside the glass. I could be wrong though, wouldn't be the first time

I don't have the materials on hand to test this yet, but this is what I am thinking about to go after air-flow issues:

Three separate chambers. The end of the tube in the vape chamber is aligned with the air intake. Not drawn to size.....

Now that looks promising in idea form anyways.

Dan, interested in your take on the various opinions expressed by the fine folks taking part in this thread - after all, you are the reason all the glass companies are shaking their heads in disbelief ("we're not even running a Black Friday sale...")

A lot of great ideas to begin with, pyrex does have its risk and I will be switching to quartz. Ceramic IMHO will not heat up efficiantly enough so it is not a candidate in my book. I have thin wall pyrex comming, so I would like to try the .29mm thin wall vs the .6mm standard wall to see what the differance is. Also extending the wick out slightly I thing helps reduce the splattering. I was looking at a slightly enlarged top wick, like a cork for the pyrex, it would allow vapor out and catch the splatters. I would have to agree with the idea of positioning the air hole above the coil at the end of the tube.

In my glass fuse attempt, I had a definite build-up of hard deposits, interestingly enough, in the shape of the coils. And I could not remove them. I don't know about lead, but it looks as if it is burned or carmelized juice actually fused or baked into the glass. I'm sure that the glass is of a very poor quality. I have even noticed some small fractures in it. I have abondoned the project until some Pyrex or fused quartz is obtained.

Yeah my fuse has run it course. I too have put it up and am waiting for the good stuff to get here. It did serve as a good experiment so i will have something to go on when my FQ arrives.

Have you ordered it yet, and if so, from where? Any idea of shipping costs?

That's it (kinda). I'm thinking a cartridge for Chamber 2 with a threaded bottom that is metal and the power lead that screws into the juice tank bulkhead.. The glass tube extends thru the top of the cartridge and attaches to the mixer assembly. You just drop the wick down into the center of the cartridge. Changing the wick is easy. The coil cartridge stays put.

 

[subsolanus]

Expanding a bit....The cartridge is somewhat sealed to prevent contamination from the vapor. It has to be vented to allow for air expansion. If the venting is to a chamber that contains vapor then it will eventually get contaminated by thermal "racheting" of the air inside. I am still of the opinion that a large amount of the heat transfer is radiative so the cartridge would have a reflective inner wall. The annual air space can be very small. One coil lead would be joined to the threaded metallic cartridge base. I'm still thinking about it. I'll put a skech out one I get it all settled in my head and process the info from the thread I havent read yet.

I'm still playing catch-up equipment wise.

I got mine from here and it says 14 dollars shipping but it might change. I emailed them and asked if they could cut it in half to save on shipping but so far no word back from them. The transaction is still pending so i think it will adjust for shipping.

Im tempted to get this one as the wall is thinner but its spendy

What about this to insulate the coil/tube?

I would avoid it just based on the MSDS sheet. No idea how any of this applies to such an application, but I would think it's not a good idea

Yeah humm, "Contains trace quantities of naturally occurring radio active uranium,
thorium, and radium (106-120 picocuries/gram) over-exposure to respirable dusts containing
radioactive uranium, thorium and radium may cause lung cancer."

I think im good with that, Not!
Thanks Killjoy1 for being on top of things

Ok, guys, Bedazzle was spot-on about this. I have been having an interesting e-mail discussion with the owner of TGP. He was very curious what all of these orders for this same FQ tube product was about. I was upfront with him and explained what it was about. He's not too hot on the idea about shipping out all of these small orders. He said that he would be losing a lot of money on the shipping containers and such. He says that there are currently around 30 some orders that were placed. Maybe a central delivery, or maybe even delving into a co-op would be a better plan? I told him that I would feel out the situation here and get back to him. Thoughts?

People would be surprised as to what in their house gives them a "small dose" of radiation on a daily and year long basis. Luckily all of the sources, off the top of my head, doesn't emit radioactive particles to be inhaled.

 

[subsolanus]

While I'm searching my quartz glass I want to try something so I use pyrex to setup. Results are good but not great. Next I use diamond cutter to make slit all the way instead of small holes. Actually, I tried to make holes with small drill bit but couldn't make it.

4.0V with 28 guage wire 10 wraps to make it 2.1 ohms.

I could taste metal for first 20 puffs or so but wires are new so it suppose to be. Surprisingly, tastes are getting very clear and because of that actual liquid flavors stands out. Vapor productions are x1.5 better than without slit. Vapor now out streight from top but also sides. I'm not saying volumes are same as my mini DID but 8 out 10 for me now.

EDIT: Somehow wick was too tight so I loosened up with narrow wick and vapor production is way up, it's getting into comfy zone for me.

I think one of the attractive features of this system is the ability to isolate the coil from the consumed air. Having the coil heat the air after the vapor is generated reduces the potential improvements. Providing more control of the vaporization process by moderating the chaotic effects of airflow over the coil is where I see the greatest potential in this effort.

Scubabatdan may want to step in here and establish a pedigree over this specific aspect of his progeny.

It might be nice to have a co-op, especially if we could get them to cut the FQ down to maybe 1 ft pieces.
Anyone interested in running one?

Ok, so here is my input on the matter. I'm going to wheel and deal with TGP to get some sent out to me. Should be enough product for around 150 15mm pieces. I'm assuming, so far, that this is the best workable size of tube right now. If anyone has placed an order with TGP, then cancel it, and I will send out samples for testing to those who are interested. How does that sound? If this works for most, then I will fill in the details when everything is said and done.

Love it! I'm in!

I was just about to say all that! Whoever runs the coop on this, put me down for about 4 feet.. Btw, I would think getting it cut in 1 foot sections would be more beneficial. 15mm might be too big for some tanks, then you're stuck trying to cut up tiny pieces.
