Having looked at this sticky, I find one category somewhat deficient (or perhaps just lumped into another)... chemicals for knifemakers. Specifically, I'd like to know where to go to get Ashpaltum. I poked around in Google and noticed Dick Blick art supply is supposed to have it, and one other art supply store does have it, but charges twice as much for shipping as the product costs.
I need this to make an etch resist, as described in one of the books I read (probably the Boye book).
Anyway, does anyone know of a source for Asphaltum? Also, I presume the canned liquid is what I need (not some other form, such as the paint in tube type).
