Problems in z black plating of jewellery metalsMay 20, 2012
Q. Dear sir,
We have a problem in z black plating in silver jewellery.
- Jaipur, India
A. Hi, Krishan.
Sorry, I am not personally familiar with the phrase "z black plating". Do you know whether this is a trade name or an acronym, and generically what the process is? Is it a blackening process that you are applying to the silver jewelry? In what way is it not satisfactory: not black enough, wears off too quickly, etc.? Thanks.
