Hey there everyone!!
Just wondering what my options were for reusing 925 metal from a previous crappy cast with investment still stuck in some of the hollow areas which I can’t remove? I have already tried the pickle and ultrasonic.
Can I melt it down in my graphite crucible(preferably an old one just for this purpose) with my melting furnace and expect the investment to float or sink in the molten metal, perhaps be able to remove it some way?
I know everyone is going to naturally suggest for me to send it off to refining, which I usually do, but that’s about 600km away and I don’t really have the time for shipping it right now.
Any thoughts would be much appreciated!!
Cheers
