Is that coiled metallic foil as a cooling unit?
It's not something I would try as I prefer no metal in the vapour path. I'm interested to know how you keep the gaps in the spiral though, nicely done!
yes, it's a rolled strip of offset aluminum foil.
it was a quick thought, I just thought of rolling it around a nail, adjusting it a bit and thanks to the springiness it creates gaps by itself.
first of all I was interested in whether the rolled foil would cool down with this labyrinth and at the same time not increase the air resistance. (the balls in the gvb mouthpiece cause me higher air resistance and after two uses they also stuck together and the air resistance is even greater. in addition, I was uncomfortable, when drawing, the balls hit my body-blocking my breath.)
upgravline was the best, but still too warm compared to venty at the same temperature.
secondly I was interested in the extension, which logically should also contribute to the cooling and at the same time not having to pull a long fragile hook.
I'm trying this for the first day and it's definitely colder than anything I've tried to use there so far.
the taste is fine. the foil almost doesn't heat up, so I don't know if it can significantly affect the taste. definitely not in contact with the herb, it is quite far from the heater... aren't the capsules also made of aluminum?
I will test more...
I will try paper, it is eco, but the question is whether it will cool better.
research good luck
Interesting, but in my experience glass and metal are not good partners, unless there’s enough room for expansion of both from the heat, glass is always the loser, hate that popping sound when the glass breaks. An alternative would be to have wider gap and using orings to absorb the expansion.
I've only tried it at my favorite temperature for all vaporizers, which is 180 degrees Celsius, and the foil barely warmed up.
But it's true that I'll do about three or four rather short puffs at this temperature and then turn it off. If it were in company, it would probably start to heat up more.
