- Hi Jake....
I used creosote at one time for a decent if not perfect sunspot, it stained
the back of the paper. It had to be 20 years ago and they are still OK,
except for the stain, which is grease like.
I use garden potash now, it's 60% potash and looks like 40% dirt! But it
makes a real nice sunspot, a little differnt from the hauptman recipe, but
in ways I like it better.....so the tradition evolves a bit, eh? Garret
Dixon sells the regular potash.....but yes, it's caustic, I used some
yesterday, it got in a paper cut, I thought I'd hit the roof. My garden
potash, I barely feel anything from it.
