This is almost certainly totally illegal now, but…..
Back in 1971 I bought my first house. The previous owner was a Shipwright in the place where I was working at the time. The last time any work had been done was, going by the newspapers under the lino, the mid 50s. Sadly a lot of the lino had to be ripped out, sad, because it was in good condition. The lino was "Pussers Lino", used in electronics compartments on RN ships, it was at least twice the thickness of ordinary lino, very heavy and very robust. I had taken out square meters of the stuff. So being young and naive, I stacked it up in the back garden, along with all the stripped off wallpaper, paint scrapings, bits of odd grot that you find when stripping an old house. It made a sizable heap. I threw on a match, and carried on with washing the emulsion off the ceiling of the back bedroom. Some time later I noticed something flickering and looked out of the first floor bedroom window, up at the flames, deep orange flames and lots of them. The thick black smoke made me think of a destroyer making smoke at high speed, appropriate really, given the fuel!!
Fortunately the fire burned itself out fairly quickly, with no damage, but I have never forgotten the flames and black smoke!!
