I am looking for the type of blackening agent (not liver of sulfur)
that is wiped over the surface of a piece. The excess is immediately
removed with a cloth, leaving black to dry in the crevices. The
substance has a paint-like consistency and comes premixed. The name
of the product and distributor would be much appreciated.
I think that black acrylic paint can be used, but is the real
product better? Thanks!
