RSword, Your comments caused me try again with ferric chloride that produced the circles you mentioned everywhere, I was pleased to see that when i applied baking soda paste the circles went away. I next tried phosphoric that brought a better definition and round spots lightly appearing in the fine crystal area. I have stopped for now on this one and will perhaps try again after i've learned more. Any suggestions on better technique or other things that might be productive.
