Doesn't welding imply the introduction of a 2nd bonding material, flux?

I wonder if something like this would work to test for chromium vi

I dont see why not. Just vape through a piece of toilet paper.......then run the test on the paper. We could do it dry and wet. It seems to me there are two possibilities of getting this into our lungs.

1. Through the leaching in to juice from the wick portion that hangs out in the tank.


2. From the coils oxidizing the wick if its too dry. Possibly. We may have to soak our wicks in HCL before we can use them. Strong acid right?

If it turns purple.....we have some work to do.

I'm not building a SS wick until this is worked out. I'll still jump on my iHybrid when I get the chance, but its looking like ceramic wicks are where its at for me with Kanthol wire. I think I will use the drill bit method and ceramic wicks. If you are carefull they will fit in just fine. You just have to pre-wrap on the drill bit and slip it in.

Where are some places to get ceramic wicks?

 

[Skeetorius]

possibly even cotton wicks. im going to continue to research this.

I worked with and welded SS of most grades, methods used were Tig, Stick, Sub arc for over 30 years mostly in confined spaces too. Heck I'm still alive!. Plasma cutting is another, and in its early days the dangers of toxic fumes were never mentioned but were known to exist, I don't know how much of this toxic stuff I took in but at a guess would have been way far more than 0.002 ppb.

I don't think we are getting our wicks up to the required temp to have a problem...there I said it The temps have been measured by other modders on another forum and they found the temp to be just under 100 c . I have touched my red hot wick before and after I learnt what temps they got from measuring the wick ,not just by the color it made more sense. If it was 800c I would have had more of a problem than a slight burn. After hearing some other views I believe that color chart incorrect for 304 and 316 ss which is what we are using. That color chart is for blacksmiths using 10 alloy steel. Make of this what you will but I feel better about it now.

Not that Germans do no wrong or make no mistakes but didn't this method derive from Germany? Also, with worldwide use at this stage of the game I would think that someone who knows a ton about this kinda thing would have brought this up a long time ago.

I have been amazed at some of the talent/knowledge that some of the ECF members have.

Someone posted earlier in this thread that they use hemp wicks. I think people using vivi nova style setups, and dripper rba's will find it easier to experiment with different wicking materials.

What are some alternative materials for use in vertical gen atty's such as the DID, Cobra, Foggatti, AGA's etc...?

Some folks have used both the cotton and hemp in the gennies without problem. I am ordering some hemp se if I like that on mine.

Caught wind of this thread last night, had to finish today. Very interested to see where this all leads. How much real risk is presented, etc.

Just keep in mind any other material will eventually find some minute to major possible risk.

Ceramic dust is just as bad. Some ceramic wicks being used have been sprayed with anti-fungal chemicals. Food for thought.

There's more Cr(VI) laying around you than you might realize. True it's more a problem if inhaled than ingested, but keep that in mind. It very well could be in your drinking water.

It's all relevant info to some degree...

Be interested in finding out how this pans out and this post also helps ensure I keep up with the thread.

This probably one of the most important post to this point in my reading. Yes this is important information but there must be context and perspective so we can access the real risk.

What kind of atty are you going to using with the hemp material?

Thanks for this post AtlantisBoy, and I totally agree with you.

Wrap a coil on a drill bit. Insert/screw the ceramic wick into the coil. The install the wick/coil onto the atty, carefully. Don't insert the wick and try to wrap a coil around it. It's too fragile and you'll likely break it. Or sometimes I pre-do the coil and install just the neg lead to the atty. Then with the pos lead loose so there's a little give, I screw the wick in the attached the pos lead. Brace the top of the wick with a finger when tightening the pos screw - there's no give - you can't be pulling the wick to the post when tightening the screw, it will snap, it doesn't bend.

Back to the topic:

Sure glad I'm getting experience this past month w/ ceramic - this thread is an eye-opener.

A critical question is it really ceramic or is it "near fused silica" aka sand?

I agree, it's anyone's guess as to how much of this stuff we come in contact with on a daily basis, but I'm glad to see this discussion progressing.

I really do think this applies to stainless steel welding and the fumes produced when welding at high temperatures. From what I've read chromium vi is produced when welding stainless steel at very high temperatures. It also depends on using tig/mig welding. The element of "alkali oxides" used in welding (which converts the regular chromium into toxic chromium 6) would not be used to heat up your ss wick.

This "Fume" while the stainless steel is being welding is airborne while doing the welding. In other words, this chromium 6 "fume" is in the air as you are welding stainless steel.

Chromium vi also appears to be green in color. It's also used as a pigment in some cases....I don't think I've seen any green color on my wicks.

Dam it ! I knew it .... Pluid

 

[st0nedpenguin]

I'm really rethinking my entire time spent as a vaper up to this point...and doing some soul-searching so far as to decide if it's finally time enough to let go of inhaling anything. I certainly don't want to continue inhaling carcinogens!

Oxygen is a carcinogen.

RIP V Ninja.

Nextel XS is a sleeve type setup. It gets very stiff when torched and can be used in the above mentioned attys.

This seems promising. Exactly which one do you use XC or XS, and why one over the other?

Thanks for the post.
