So what do you guys think, is the glass core more convection-only while the ss core offers a bit of conduction as well?

No. Assuming you don't let the heater touch the load, there is virtually no conduction going on with either.

I think any difference can be attributed to the fact that glass and SS have different properties regarding heat retention. Glass has insulation properties that SS does not and will be cooled more IMO by the act of taking a draw vs. the SS. In theory (I haven't actually used one personally) the glass stem should have a purer taste, so the tradeoff is worth it to many.

Assuming that we can get to the same effective temperature with both style cores, what do you think accounts for the darker abv and (slightly) more complete extraction of the ss over the glass core?

If I remember correctly the SS core holds the heat better so it takes it a little longer to cool off when vaping. But that is just my SWAG(scientific wild assed guess). So if it holds heat longer then I guess you would get a darker roast on the material. That's my SWAG on it.

From my experience with my SSV, I would guess that one cannot simply crank the temp to achieve equivalent extraction. My SSV wand has a deep bowl and increasing the temp couldn't take the ABV any further. Instead, I found that effectively moving the bowl closer to the heater - via Tweak's EZ bowl mod - did take my ABV darker.
So from my experience, I would think that the inherent properties of the SS produces thicker hits and further extraction that cannot be matched by the glass core by simply increasing the temp.
I chose SS. I've had to delay my HI, but for not much longer. :clap:

Also, from emails with @Alan, he stated that with the HIBrid you can get the ABV "about the same darkness as with the ss core". "The draw and roast is just a little slower with the glass core".
When comparing glass to ss he said "With the stainless steel core, I can get maybe half of my lungs full of vapor before I feel the need to stop and fill them the rest of the way with room air. The vapor is much more dense. The hits are much more intense. You can get almost complete extraction to where the ABV is coffee brown." I'd assume from this that the ABV from the glass HI isn't quite as dark as the darkest of ss and HIBrid ABV?

Glass = HIbrid
I do have the glass one and like Alan say it is much slower... You can get it as dark or almost as SS but it will take you a few sipping and working on it, on the other hand you'll be avoiding combustion really easily. It as some advantages btw... With the good draw it can be really consistent long hits !
Also glass is much more fragile : after a small flip over the glass core is loose and moves a bit. Still working fine but now I'll have to be extra cautious.

Oh, Alan's dropped the glass heater option (glass w/o ss heat shield) and is offering a choice between 'HIbrid' heater (glass w/ ss heat shield) and ss heater options, then?

Glass may be fragile, but according to Alan "The only way I can see the glass breaking is if someone pries at the hole in the end. "

Also, there's this "I expect that the wood will have a longer life with the glass core as less heat is conducted to the base of the wood."

I like vaping at higher temps usually but the unique heater is one of the biggest reasons I'm going for a HI over other logs. But I chose glass over SS not only because it's more unique but I figured if it can reach the same effective temperature, you can still high temp vape, so it shouldn't be an issue...

I am buying a HIbrid core HI and my friend is getting a SS core one so we can compare the differences easily... I am still really excited for my toys to arrive!

I emailed Alan asking about the SS/glass heat thing we've been discussing before I read this whole page. Hopefully he sees this first and doesn't have to explain it all back to me ;)

That's it !

IMO HIbrid can get to the same temperature but without the same "flash" extraction SS core can. That's why I would use a SS for concentrates or when you want this flash extraction. However, I could still see myself use the Hibrid with a good bubblehash to enjoy the taste at the fullest.
It is fragile indeed, not broken yet... Simply moving around a few millimetres.

I just thought I should get back on the list. We never know...

LOL before it is all said and done, i myself and proably most everyone on this thread will have every model that @Alan comes out with. I am okay with that idea.....lolololol..although my wallet at times may not be!

Are the HIbrid core ones very fragile? I would have to take extra consideration traveling with one then...

@hoyo77 - Good to hear you have your HI connected to a VVPS. A great way to dial in a precise temperature. Nothing new on the horizon yet. Just need to get some GTV units made along with trying to get through the list. Hopefully, I won't hurt your wallet too much.

@exit - I was able to turn your HI the regular size and still get a 13mm wooden tube from the same block. Finishing it up now with a batch of others. Here is a photo of the heating element stuck into the glass heater cover. There is stainless steel in the air path, just not as much as with the ss heater cover. The glass cover is fairly thin but is held in place by six aluminum prongs. The idea is that the prongs will bend to absorb the shock energy if the unit is dropped. There is not much mass to cause damage to itself because everything is so light weight. I am now making the glass cover slightly shorter so the screen is all the way to the end of the glass tube. It allows you to get even closer to the heating element for slightly hotter air temps. I am also no longer using the glass beads on the heating element wires as there is no chance of them shorting out with the new design. The heating element is identical to the one used in the ss heater cover. It just doesn't have the small ss sleeve over it. The amount of heat going into both is the same. The glass heater cover configuration just can't store as much heat energy as the ss heater cover configuration. The ss heater cover doesn't store a whole lot more energy. The diameter of the ss is 3/8" vs 1/4" with the glass cover. The length of the ss heater cover that is available to store the heat is only from the air intake slots up to the top which is not much longer than the 1/4" ss sleeve in the glass hc.

@Scott A - Glad to hear you are getting the extraction you desire with the glass heater cover.

@EveryDayAmnesiac - I like to be able to inhale through the roasting tube for the entire breath rather than taking a high temp hit and then mixing it with a gulp of fresh air to complete the hit. It seems a good way to extract since there isn't much left when subjected to the higher roasting temps. I do still find myself pulling a Vapor Lung now and then using a higher temp. The higher air flow you can get with the VL seems to lower the roasting temp a bit. Sometimes it is just fun to have a bottle of thick vapor.

@grokit - The ss heater cover contains more of the heat being produced buy the heating element. It captures more of the radiant heat that the glass cover allows to transfer to the wood body sides.

@Bvapst - Sorry to hear about the flip over. Sounds like the aluminum prongs did what they were supposed to do so the glass wouldn't break. The bent prong is allowing the glass to move slightly. The performance should be unaffected by it. If you want to tighten it back up, you can remove the two screws holding the aluminum plate down to remove the heater cover. Then you can slide the glass out of the aluminum plate and bend the prongs back into position to that it will be snug when you slide the glass tube back into place. Trying to bend the prongs back with the glass tube installed is not a good idea. If the glass does break, I only need to send you out a replacement glass tube.

My HI actually took a fall off my desk yesterday, my dog is very clumsy lol, and I think its the prongs you are talking about Alan that loosened up. At first I thought the glass was broken or something but then I realized it was just moving in around a little bit not broken. Im glad to see that it is just an easy fix to snug it back up.

edit- I got to give you some props Alan. I really like the ingenuity of that design to keep the glass from breaking as easy.

Same here. I thought directly "no broken glass sound", that's good... But I've found the glass tube moving around and just thought "it was safe nicely in place" .

Thanks @Alan
I'll probably do that later if I find it is more loose but I'm afraid another accident would be "drama". Is it possible it could slide off without removing the screws or if it get a hit ?
If I understand correctly : after removing the screws, the glass heater cover (tube only) should be removed from the top easily ? So the glass is "snug" in the aluminium plate too ?

HI, everyone! :wave:

I've been remiss in showing off my new glass-core HIsaber (sorry for the crappy vid!). My goodness, she's gorgeous and works like a champ. First run was as if I've used it for years. It's HI-ly figured walnut with an ebony cap. Alan also turned a matching roasting tube with a glass tip, which didn't make the vid because I was too HI :freak:.

You'll see I compare it with my striped maple SS core HI Alan turned for me just over two years ago. Time for that one to take a well-deserved rest.

Outstanding service and craftsmanship, as always @Alan. I'm so proud to own these works of art and HI function. Thank you!

Looks awesome, Vhole! :rockon:

Turn that sucker up to 11 to get that extra push.... over the cliff. Where can you go from there? Where? :shrug:

My next HI is going to be glass core as well. I envy us.

Thanks, @Stu! I envy us, too.

I'm having a blast with this HI. I paused for two minutes in honor of @ilovebOObs, chanting "holy fuckballs" as he'd want me to do.

Then I prepped another load and vaped myself to another galaxy.

Dare I say I'm gunning for JedHI Grandmaster status? Yes, dare I.
