Hi guys! I am having trouble keeping the 24k gold foil applied to my argentium silver pieces from also tarnishing in the liver of sulfur solution.
I learned that if I leave a piece or argentium too long in the liver of sulfur, the black deposits get too thick and chip off. So I do repeated approx 15- 20 second dipping, soapy brass brushing, re dipping, until I get the silver to a nice deep black.
The distilled water and liver of sulfur solution is in a glass beaker, on a coffee warmer hot plate. (Approx. 120 to 140 degrees Fahrenheit, Midas brand liver of sulfur)
I roll my own 24k foil to about 0.02 mm (measured with a micrometer).
By the time the silver is deep black in color, the 24K gold foil has also tarnished!
What am I doing wrong?
I wonder if I am burnishing the 24K foil too long, at too high of a temperature and the foil is diffusing into the silver? (I use 700 to 800 degrees Fahrenheit) But using a lower temp on the hot plate created issues with adherence of the gold foil to the silver.
Am I using the wrong liver of sulfur solution temperature?
Any thoughts or ideas would be so appreciated!
