I would like to think that I have a fair knowledge of metallurgy, as
with working with metals you need to know how they perform when
The question I have is. Is it possible to induce porosity to a piece
of metal while performing a simple sizing job on a ring?
I sized an 18 carat white gold ring up a couple of sizes, nearly a
year later the customer came back as the ring was cracking, and has
been told by another jeweller that the metal is porous because of my
work in sizing! This to my mind cannot be possible! Is not porosity
in metals induced during casting?
Any ideas would be greatly appreciated.
