Ahhh ... here you guys hang out! Finally I found you! Thank you tseuq for pointing me here!

And thank you very much for your report!

Since you and Aum_Shanti both recommend the Bald T for 5-Meo ... I get, that the molten substance does not travel up the walls of the cup ... otherwise you probably would have said so. (Because the alternative would still be the Source Nail where the walls are heated too.)

Now I am still curious about the residue that's left behind. Is it black stuff?

I am asking this, because I believe it only gets black, if a small amount gets burned instead of vaped ... and I would love to avoid this.
