Hi it's me again lol
Please is there another substance less nasty than asphaltum for
making silver for etching?
I was one of the few artists trianed on stone lithograph printing
press. Could Gum Arabic(usa name) or Guar Gum(rest of the world) be
used to mask on the silver?
We used it and printmaking and stone litho uses Nitric and
Hydrochloric acids so I was just wondering as I have a pound of the
stuff in powdered form. :)
