My brief research indicated that blue vitriol is a mordant, not
a dye-stuff. Have you made some soap with blue vitriol in it just
to see what it looks like? That would give you a benchmark to
compare substitutes with, and you could display the real thing
while giving out samples of the safer substitute.
