AnswerHello Krunal
Is it that you wish to make Niello- a mercury containing black inlay material that is packed into carved or inlays in gold work pieces?
I have a number of formulas of different grades of processing the formula and methods for producing Niello that I can send to you ( it's far too lengthy to write here in this forum)
BUT I would like to know your skill level - honestly - as it is a dangerous process that I would not recommend for the beginner or even someone that is fairly new to jewelry making, however if you can alloy and raise and lower karats, you can probably handle the process, but there are extreme dangers and it is best done outdoors and down from the prevailing winds.
If it is simply to colour yellow or white gold black , and not just an oxidation, I can send you patina recipes..so I need some more information from you and then we can go from there.But do let me know your intended background ( meaning: the piece you are going to make or what you actually want to do and what karat your material is as well as the color..)
Krunalji, Do Please rate your skills fairly I don't want to steer you in a direction that is over your head or requires expensive or high-tech equipment when a 2 dollar jar of chemical may be all that is needed to transform yellow gold of 24 kt to 19 karat yellow with an oxidized etch! Looking forward to hearing more from you,
Best Regards Ari
