We just started casting de-ox silver with our Memco casting machine.
However, the de-ox castings come out very brittle, where as the
regular sterling and gold castings come out fine. Our casting
temperature is 1796 degrees Farenheit. After casting, we wait until
there is no red in the button before quenching. Do we need to mix
the de-ox with regular sterling (50/50) ratio? Is the casting
temperature too high? And ideas?
