I found my way here killing time waiting to pick up my daughter from pre school. I have a son in seventh grade, and I was curious about making soap as a project. Which made me curious about wood ash, charcoal, lye, and natural chemistry.
Anyway, that's why I'm here.
to the guy that did the salt peter article, I do have two questions:
Can animal dung/urine be used?
Also, I need some clarification here:
Now allow the mixture to evaporate. A container that is more like a tray than a barrel will evaporate off the water more quickly. The evaporation portion can be done in batches.
Heat is now added to the solution to bring to a slow boil. So boil the saltpeter ley to begin concentrating the solution.
If I have allowed the mixture to evaporate, how can I then boil it? Is there a step missing, or am I just being dense?
