There go’s the reputation of argentium silver being firestainproof.
I wonder under which condition CATRA performed their firestain test
and yes I know that they described I downloaded them (both) but
practice and statements from others show otherwise.
Are we all doing something wrong here?
So, if Argentium does oxidize being "7 up to 8 time stronge"r then
other silver alloy’s, Does that mean that regular silver get’s
oxidized in 1 day compared with Argentium?
Frankly, I never noticed that but reading the PDF- reports from
CATRA that’s how it sounds.
I worked with Argentium (960 to be specific) aswell as with S88,
S57NA (from UPM) and regular sterling silver.
They all will oxidize but not in the rate as I’m supposed to
I must complete my writing that S88 and S57NA are not mentioned in
I’m just talking out of experience with the different alloy’s.
Now the same with the firestain PDF-report.
As the report shows, the’re is no firestain to reveal after
performing that test.
Their test is performed with 1 trial (I think) and with one
temperature (580 C).
However, firestain will start forming from a broader range of
Why only testing at this temperature?
It all becomes fuzy to me realy.
I’m confused with all the statements of people ranking Argentium so
The funny thing is that you can’t do much wrong other then buying
the product as it is and following the working procedures.
I’m not setting the rules and I don’t have all the testing abilities
but what is left to believe? Being a gold- silversmith with enough
experience to know what to do and not, I understand others problems
They are trying to make a wonderful piece and just don’t get the
I do start to believe that Argentium is promising more then it can
stand for pointing towards firestain and oxidizing.
This is an attemption to place the company in a bad spotlight, not
Fact is that many people are confused -as I am- and they don’t get
the solving answer to a straight forward question.
So, what makes the difference between a perfect argentium workpiece
and the troubles people encounter with this alloy?
