If you soak the paper in cold alcohol, you're just making work for yourself. I have used newspaper to make touchpaper and it works fine. No large crystals to break off. Just dissolve KNO3 in hot water, dunk your paper for about 5 - 10 secs and hang up to dry. Incidentally if you hang newspaper on the washing line then fold it up when dry and put it in an empty washing basket, the neighbours are comvinced you are a nutter. They were convinced when I did it anyway. Lol.
Yes, you just need a reasonably absorbent paper. My method here:
Blue Touch Paper
BP type comps take fire from touch paper no problem. Also ones with REd Gum / antimony etc. Just that some of the slightly more exotic comps need a bit more heat to start. The alternative to quick match is a thin layer of (compatible) easy to light prime...
