Propane burner smell
Sometimes when I use my blowtorch (e.g. when it is in a small furnace just started and the lid is closed) a strange smell appears of 'unburnt gas'. It
appears that too few air is added. It is not really pungent, but a distinctive smell which differs from a typical gas smell.
What is this ? Really an incomplete combution ? But incomplete combustion results in CO which is odorless, so what has such a smell ?

it is added to most gasses so that they can be smelt if they are leaking.

Wouldn't the ethanethiol burn as well, it has a NFPA 704 flammability rating of 4.

Yes, it would also burn.
The only time I've smelled unburned gas when using a propane torch, it was leaking from the valve.
Please remember: "Filtrate" is not a verb.

I like it too... same with unburned gasoline, and a few other similar smells.
