My use of oxidizing agents other than WinOx is limited.
As a beginning silversmith I started using liver of sulfur to
oxidize my silver. I was never happy with the results and especially
I was introduced to WinOx when I met Bob Winston. He was the first
and only sales rep of our product Cupronil.
The use of WinOx on silver is like painting the project with a black
paint. It produces an instant dark black finish.
I agree WinOx has a long shelf live. When I heard Bob Passed away I
bought all the WinOx our local supply house had. I was not about to
be without WinOx. I still have some of those bottles stored in sealed
I agree with Miss Khennesey, Bob’s Daughter in law. Bob was a REAL
character. I remember asking Bob how he did not get fire scale on
his cast silver. He would reply he used a reducing torch to melt the
silver then he would hold the flame on the button for a short while.
I would argue that that would not prevent fire scale. We would have
that discussion every time we met. He never buffed his silver as he
tumble polished all his castings.
One time after our many discussions I asked him to take one of his
cast bracelets and hit it with his buffing wheel. He walked across
his shop turned on his buffer and in about 10 seconds let out with a
long string of choice words. Buffing the bracelet exposed fire scale
that had been hidden by the tumbling process. He was shocked to say
I wish I had been able to show him my simple method of preventing
fire scale on castings before he left us.
