Answer
Hi Cecilia,

No, soldering copper foil is not dangerous, but breathing the fumes from flux could cause health problems if you solder in a room with no ventilation. Therefore, you should take precautions. I use a fume extractor, as well as working in a room where I can have windows opened. You can see one type of fume extractor here.

Until you get a fume extractor, have a fan blowing from behind you. It will blow the fumes away from you. Don't have it blowing on the glass because it will cool the solder to a point where it won't flow properly.

You can also solder outdoors, on days when there is no wind. Many of don't live in a climate that allows us to work outdoors for many months of the year, but take advantage of it if you can.

I hope this helps you and calms your fears,
Sue
