Hello Guys,
found this forum these days and its amazing! Good job done and doing!

I wanted to share my favourit way of vaping cause I often red about trouble with this.
I use a glasspipe (not a Bong) with a coupling for standart 18.8 bowls. The bowl should be as high as possible, mine is 6,5cm + male adapter. I put a screen in the lower end, so that nothing could fall through the bowl if you put something in, that´s a bit tricky cause screens slip around very easy. Now you fill it ca. 1cm - 1,5cm with vermiculit and put your spice on top of that. Place a second "hang-in" screen at least 2cm above the spice and put ca. 5mm vermiculit on, the more the lower/slower the heat comes throug.
Now hold the flame of a torch lighter at the middle of the vermiculit and slowly start to inhale. The close the flame is to the vermi´, the hotter the air/thicker the vape.
The vermi will first absorb the spice till the heat is enough to evaporate.

Never had any problems this way, good luck!

I don't think vermiculite dust will be very good for your lungs.

i am almost certain (99.9%) this is terribly unsafe.

I have worked with vermiculite, the dust is terrible for you to breath.

It wouldn't really be dusty if it was washed before hand. I don't see the vermiculite becoming more dusty with heat (it is made by super-heating minerals). Is it really that bad? Really, you're already inhaling foreign substances into your lungs.

Interesting doodad! I love my changa, though.

pretty bad, especially if it is contaminated with asbestos (which is not uncommon)

some shroom growers like to wear a mask when just working with the stuff (i'm not that cautious, but they do exist)

i see no reason OP couldn't do the same thing with a silicon carbide foam filter, which would be completely safe and inexpensive.

Oh! I was thinking it was pearlite!
I know pearlite is probably not much better than verm. Pearlite might work better, as it has a huge surface area. But you're right, silicon carbide would be better. I know some folks have short budgets, but at the same time, you get what you pay for.

Why spend so much on root bark, and other stuff, look for a deep experience and then make a pipe out of junk yard stuff? I don't mean to put anyone down, but the 30 bucks I spent on my glass bong was one of my favorite investments. There's pretty great attachments that could vape freebase for like 10 more dollars.

I would never do this.

its $5. even if you can barely make rent you can finagle it (its more with shipping but still)

Of course you should wash the vermiculite before use to discart dust. I dont think it´s bat for the lungs because even when its fully glowing (without spice) there is not even a touch of smoke or taste . Its the best way of many ones I tried before: glass/ceramic globules, thick layers of screens, wounded electrolytic copper, steel wool, ash and even some different vapo-bowls, but non of this worked comparable to vermi.
I use this vermiculit for reptilian incubation and I dont think there´s asbest in (especially if youre living in the European Union where asbestos is strictly prohibited)
Just give it a try and enjoy!

those vapo-bowls are bunk, and that list looks pretty sub-par (seriously, try those filters i linked). if i were you i would make 100% sure inhaling heated verm doesn't have any negative health effects. you probably won't be able to confirm asbestos contamination, but apparently most asbestos comes from a montana vermiculite mine, and most of its production was sold to the US (so a european source is actually a good thing - even though asbestos is expressly forbidden in the US too).
steel wool is great for resting your DMT on, but i wouldn't use it as a vaporizer.

i guess if it ends up being safe (i still feel like the heat would break down micro-fibers which would be inhaled and not tasted - but this is pure speculation), and it works, then there is no reason not to do it but...

i still wouldn't.

this got me thinking about a mock vg top



instead of the OPs suggested use of vermiculite, why not use sand or NaCl on top of some changa
