I recently heard about an etching product, which is a photo polymer
film made by Dupont called, Imagon . I believe it is similar or the
same material used to etch circuit boards. A fellow artist has used
this material to etch with ferric chloride on copper, he is getting
a very fine etch line. I was interested in using this material and
checked on line. I came up with a graphics company that sells this
material. The web site is:

I also found a tutorial on how to use the Imagon at this web site:

The artist I know has purchased Imagon locally, so you might check
out graphic companies in your area. I hope this helps
you.

Hi there, there are a couple of ways to dispose of Nitric acid short
of pouring it down the drain. You can neutralise it with sodium
bicarb. If you can get pH strips, they’ll help you work out when to
stop adding bicarb. Just add the powder a little bit at a time and
stir. When it’s neutral (or you’re getting an excess of
un-solubilised bicarb), you can pour the liquid into an absorbant
material, let it dry and throw it out. The acid will get warm as you
add the bicarb. All the necessary protective gear should be worn
when you do this (eyes, mouth/nose, skin - including feet) and clear
a decent space around you. The other alternative is to ring up your
local government department and get the trash disposal section.
They’ll be able to give you the name of a few companies that will
dispose of the acid for you. The disposal company might require an
MSDS from you on the acid. Hope this helps Eileen
