Hey guys, I’m fairly new to the world of casting so I have a lot of dodgy porosity filled castings lying about that id love to re-use in future castings, I read everywhere that I should only use a max of 50% scrap in my future melts, anymore and ill see defects in my castings.
Whats the best way of preparing dud castings for re-use? pickle, scrub, dry and back in the electro melt?
Is there a way to turn that silver back into new silver grain that will be appropriate for casting that I can do myself? Or do most people send these castings back to a refiner?
Whats your process for recycling scrap, id love to know!
Thanks so much for any help!
