Heatless Toner Transfer:

First experiment with this technique: Very successful.

I used ordinary 70% Isopropyl alcohol with acetone in the ratio given in the YouTube video.

And, I must admit that my technique was very sloppy.

With a bit of refinement, I think I would be inclined to use this method over heat transfer

because it gives very good etch images with an absolute minimum of fuss, bother, and

unreliable results.

Next, I will try 70% Iso with Xylene.

Besides:

You are not going to take a bath in the stuff!

At most, you will have a few CC's out in the open, or a few eyedroppers' full.
