WOW! Thank you to all who responded, have not acted on the metal yet,
I think Leonids definition and explanation is fantastic, did not know
about the Potassium nitrite technique, also thanks to Pedro for
mentioning it from Fischer. depending on how easy it will be to
purchase the Potassium nitrite, i did see offers on Ebay and amazon,
was there a difference between that material and what is being sold
at Ficher in germany. there are huge price differences per pound.
as to the forging of the ingot, I was following that thread,and I
forged my ingots into sheet and wire for a long time before
purchasing my mills (15 years), but I do forge them minimally to
shape before my milling begins.
I do like the idea of the last resort/ trial to clean up the metal,
but am not sure about the health hazards vs the costs of refining
balancing act. But the info sounds fantastic. Larry I will pass by
and bring the metal with me,it is thursday, I just got your message.
My suspicion on this matter is that the mix of alloys over time has
gotten some materials in it from different sources, like deoxidisers
and silicone? that may be unbalancing the alloy. " it isn’t my
fathers generational alloy any longer where it was gold silver copper
and perhaps at worse zinc".I am also wondering about the crucible
contamination,I guess it may be possible that it had contaminants in
there? even though in my shop I have strict rules about NO mixing
crucible use, ever. but I can only guess.thank you all, I will get
some potassium nitirite (I welcome any advice on the point of
purchase), but will have to setup outdoor to do the cleansing.
