I'm in the process of tearing down an old toilet in my house from '48 and encountered Eternit pipes that I carefully had removed entirely, wrapped in plastic, and took to the recycling center with. I read up (and got incredibly worried) about asbestos due to this.

Now, as I continue tearing down, I see that the toilet's wallpaper is holding a plasterboard that sits on top of a wallpapered masonite board glued to the concrete behind with a brown adhesive.
Could this be black glue or is black glue completely black?

What else could this adhesive be?

Close-up view of a peeled wall showing layers including wallpaper and a brown adhesive on concrete, possibly discussing black glue in a renovation context. A bathroom wall being renovated, showing layered materials including wallpaper, drywall, and brown adhesive on masonite, with visible cracks and pipes. Close-up of a wall being renovated, showing a brown and yellow adhesive layer between gypsum and masonite boards, with a small nail visible.
 
I would definitely classify your pictures as regular contact adhesive.

Sounds reassuring! Anyone else agree or have a different opinion?
 
What I've heard is that you can't just assume it's black asbestos; it could be present anyway.
The only reliable way is to take a sample and send it for analysis, which costs around 500 SEK, and then you'll find out if it contains asbestos or not.
