Geez, this etching that I started working on
back in March has been one of
the most frustrating and difficult
plates that I’ve done in years.
It began as an experiment using
sugar lift ground and the saline sulfate etch.
I could tell early on that
the sugar lift/aquatint ground was
fouling biting and wasn’t going to
Here’s the first proof…which looks
nothing like what I intended!
Not one to just give up, I dove right in
and began to add line work, burnishing
and more aquatint.
Here is the latest proof, hot off the press
I have more burnishing to do, and will
also be adding more line work
here and there.
This is the first real print
that I’ve done with the saline etch,
it seems to have a lot of quirks
that I have yet to figure out.

Today was my third (and final)
“safe etching” workshop that I
did at Tiger Lily Press.
It was a brief introduction to the
saline-sulfate solution used to etch
zinc plates. You can find info
on the technique here.
I haven’t done an etching in
about 3 – 4 years, but the workshops
got me interested in getting back into it.
Besides I need to know how to use
this technique in order to teach it!
I’ve chosen the old-fashioned
“sugar lift” (sometimes called lift ground)
method to make my image. It’s
been 30 years since I tried it.
It’s ridiculously tedious
and time consuming I have to say.
This is the plate after etching
four times at timed intervals.
Beginning with 1 1/2 minutes and
up to 3 minutes.
After applying a rosin aquatint, I begin to
paint on the sugar lift solution for the next etch.
There are numerous recipes for it, but all include
sugar, water and india ink. Mine has a
bit of liquid soap and gum arabic added.
Once completed, the solution
needs to dry thoroughly.
Then a thin layer of hard ground is applied
to cover the entire plate and dried.
Now the fun part…
The plate is placed in a sink
of hot water…and then I wait.
This part takes hours and hours of time.
The point is that the hot water will
be absorbed by the sugar solution
and begin to lift off the hard ground,
thus exposing the aquatint underneath.
It works, but it requires constant water
changes to keep it hot enough. I also have
to use a brush to gently
help remove the ground. The drawback to
brushing is that it’s very easy to
scrape off the delicate rosin.
(which I’ve already done)
This is the plate once
the sugar lift has been totally removed.
I etched this stage today,
but haven’t pulled a proof yet.
I can tell that I have some foul biting
in places, but I thought I’d etch at least one more time
and then print the plate
to see exactly what I have.
I can always go back and make
corrections with line etching
or drypoint as needed.

Once Tiger Lily Press
moves to our new home, sometime in the
next month or two, we will no longer be allowed
to use nitric acid to etch zinc plates.
So in order to keep etching alive, I’m
learning how to use
the saline-sulfate etch.
Today was the second day of
I didn’t have the opportunity to
take any photos this time during the process,
but you can check out a previous
