I’m having a problem with this yellow tarnish that appears on newly
completed pieces. I mostly work with turquoise and silver.
My process is that once the buffing is complete I clean the piece
with a tooth brush and dish soap. Then into the ultrasonic. Then
another scrub with tooth brush and water. I then let the piece dry
out overnight then I put each piece individually into a zip lock bag.
About 1 out of 10 pieces gets this yellow tarnish on the flat back,
polished silver side. It comes of easily with a polishing cloth or a
quick touch of the buffing wheel but I’d rather prevent it as I
usually discover it the day before I’m getting ready to deliver the
pieces to a client.
Thanks in advance…
