Dear Orchidians,
I am having some problems with porosity.
On the same cylinder, I have perfect rings and other ones with some
porosity, specially those ones that weigh more than 5 grams. I am
working with silver, using 980C for casting with 560C on the
cylinder.
Can somebody help me to eliminate this porosity problem?
Thank you and best regards,
