Hi everyone
I am curios if anyone else had experienced this
I set out to do a handfull of boards that almost looked like memory fingers once cut
I figured minimal bsse metals so covered in hcl and added potassium nitre untill all gold in solution
Problem..gold never seems to go into solution after waiting days and visibly there's no more basemetals i still see gold foil/flakes. :shock:
I gues this is where my color blindness comes in
I believe the color of the solution (dark green to brown) and the little specks of board and mask are very reflective and appears like gold
The way i figured this out was by adding 100ml of bleach while the solution was still warm and all the so called gold was still there.
This i have enough experienceto know was then not gold but again i am left with to much nitric :lol:
I think this time i will try cementing instead of the tedious evape
