I understand the stuff inside the drum to be vaporized creosote.
The stuff that dripped out was tar like but I understand this to be 3rd stage creosote.
The Blow torch gases are methane and methanol as well as acid and Carbon Dioxides, however, creosote is present in these gasses.
Here's a video showing the vapor, then gasification
I'm not exactly sure what "3rd stage creosote" is. I googled it, and I found it related back to chimneys, where they just generally call everything creosote.
The terms "vapor" and "gasification" are being used loosey goosey as it relates to making charcoal. You can't see water vapor, and the process being called gasification is actually pyrolosis.
