You guys are both like encyclopedias, thank you so much for the long, explanatory answers and the pictures. Everything is much clearer now. I will no doubt contact you again with more questions once I get the blowtorch.
As for the appropriate kerosene/paraffin to put in these blowlamps (or Petromax lamps)...
When I was a child back in the 70's, everyone used to have a heating stove in the house, one in the living room, one for the bedrooms etc, because we didn't have a natural gas infrastructure in the country. We all used to burn wood or kerosene (gazyagi - gasoil would be the mot-à-mot translation from Turkish) in these stoves, and this fuel was very easy to find and widespread in the country, everywhere. We also used to have constant power shortages, so nearly every family had more than one wick lamps which also used kerosene.
Now that we're using natural gas, kerosene has become more and more difficult to find. A few years ago petrol stations used to carry them, now they don't have it either. All that I can find nowadays is this blue/orange/yellow colored 1 litre kerosene bottles they sell in Bauhaus/Praktiker... They are artificially colored and have fragrance added in, so that when you burn it the room smells of a stupid pine, orange or lemon odor...
My question is, what do you guys do in Europe? Can you still find the old style kerosene? Is this new colored fuel harmful for the Petromax lamps and blowtorches? Do they leave soot after burning (rußgeschwärzt?)? What would your recommendation be?
Kind regards...
