How about tungsten? Don't know anything about it except that my wedding ring is made of it and it's impossible to scratch

 

[TommyDee]

Indeed, tungsten is super freakin' hard. Machining cost might be an encumbrance as it might require diamond grinding.

God damn posting images on this site...somebody give me a new primer on posting pics. Posting pics to this forum is utter bullshit...

I really like www.turboimagehost.com
There's a few other good ones as well but turbo works well for me.

Edit: Thought you hosted on Tinypic who black balled FC or something like that a while ago.

I think tungsten is a really bad choice for a number of reasons.

here is one https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4579035/

Thanks so much @Stu

It took awhile, but I finally got comfortable with imgur and they got a stick up there ass...

Also just realized that I double posted, so please mods rectify that. These turbulent times make me a little bit loopy...

Tinypic fizzled out and Imgur doesn't like us. LMAO

I use https://postimages.org/
and has worked great.

Avoid Corona, Find that TP,
and...

Happy Vaping!

It has been my go to since tiny image tanked.

Choices.

 

[vandalizedbythelotus]

Funny you should say that @BabyFacedFinster . One interesting material would be the ceramic alumina. Super-neutral taste and completely inert. Wouldn't work with an IH though so that's out.

the glass OG works fine with an IH so i maybe this would too. not as fast as a regular metal tip ofc and pulse heating is a must but the glass tip works.

 

[stark1]

You must mean the glass stem. With cap/tip. Works?

Wait. OG has no tip. So, Cap?
(A tiny more mass should help. A small disc magnet?)

Back, to Dreamland.

 

[vandalizedbythelotus]

the OG stem/tip is the same segment yes. i just mean the tip portion gets heated from the cap and works very well with IH. but pulse heating is a must because the glass needs extra time for the heat transfer and the cap by itself heats very fast.

 

[stark1]

No convective heat?

Maybe it’s a good thing?
I was posting photo’s until a member responded that I my picture’s were offensive?
“M” cap is a decent medical device to get Through opinion’s!
The long stem is the bomb!

 

[TommyDee]

Good point @vandalizedbythelotus . If there's a screen, that too would heat. I like that. That may just solve the combustion problem with real-time IH heating.

An update on the real time heating of the VapCap using an underpowered IH - "FUCK!"
1/2 bowl, 30 seconds, 1 draw, and dark ABV. These draws are close to what I can do with Muad Dib using concentrate. This is as close to a bong hit I've achieved yet with a VC. I can't even come close with the Launch Box.

I always enjoyed seeing your pictures.
You know what they say.
One bad apple.
Or in this case maybe one mouldy bud.

 

[TommyDee]

Well what do you know - after cleaning up my last flame-out (full power IH is too hot for active heating ) I took a close look at the '18-M CCD. It doesn't actually have a lip that captures it; okay, noted. Last time I replaced the CCD I used just the center to punch it in there. Worked great and the CCD was pretty much conical. But remember the earlier discussion of making use of those openings along the edge of the CCD? I got the CCD to fit convex! It is locked in and pushes out easily from the stem-side.

If you want to try this I'll tell you how I got there; first a fresh new CCD installed using a pocker. Something that will reliably lock on the center hole and broadens quickly. The CCD will go cone shaped and install. Remove the CCD with a tube from the stem-side. Maintain the conical shape and put the CCD back in with the center proud toward you. Use 5/16" tube to finish seating the CCD.

You now have much better flow through the holes along the edge of your CCD when the bowl is stuffed with dense herb.

Stems, we love 'em. Lots of talk about cooling stems, cool vapor etc. I though it may be interesting to look at the potential heat sinking ability of common stem materials. Below is a list of the approximate thermal conductivity of some potential and common stem materials. The higher the number (k) the better the heat transfer.

< 1 Wood low and varies with species, gran direction moisture content etc.
1.05 Glass
1.14 Borosilicate Glass
14 Stainless Steel
20 Titanium
76 Platinum
240 Aluminum
420 Silver

I'd say it's reasonably certain that glass and wood are poor choices for a cooling stem. eeek you say but but beads and nipples! Okay, for glass to just match SS it performance must be improved by 14 times! Seems pretty unlikely, I'd take that bet. 14x just to match, good luck.

I realize this is a simplistic view but I think is still speaks volumes.

Cheers.

@Planck - so lower numbers could translate to less condensation maybe?

@Planck - so lower numbers could translate to less condensation maybe?

Yes I think that is almost certain. I say almost only because I've never read a paper that proved that is what happens. It is the way most materials would behave.

"Get all the jones with Quincy Cones!"

 

[TommyDee]

I was surprised how little glass condensed. Definitely knew wood was condensation resistant.

BTW: the reverse CCD has a notable change in draw resistance. Impressed after an evening with it.

 

[phattpiggie]

Thank you for the reminder @mucsusn, seems a lifetime ago when that stem was made.

@Planck having made both glass and SS lined stems I can say SS loses out to glass on flavour but makes up for it with its ability to rob heat from the vapor.

As I've said before if I'm paying up to $100/g for concentrates I want them in me first time around rather than stuck to beads, dimples or a twisted tape turbulator only to be dissolved off in some Iso.

The other thing that makes a difference is the bore of the lining.
Smaller bore accelerates the vapor which in turn scrubs heat.
So far I've tried an ID of 4.5mm, DV size, 4mm which is my regular size and 3.2mm.
3.2mm being the size in my DD stem.

 

[TheThriftDrifter]

@phattpiggie Just to clarify for my own hazy brain.

Glass = less condensation.
Larger bore = less condensation.

A huge shout-out to @mucsusn
and PP for clearing up a conundrum. Seems
I had acquired a mystery stem the provenance for which I knew nothing about.
