I've been working my way through several hundred pounds of xray room sheeting, melting/cleaning/fluxing and then pouring into ingots. I'm probably better than 3/4 of the way through the stuff, and so far so good.
Yesterday, I left about 20lbs of ingots on patio paver blocks to cool. I promptly forgot about them, and they stayed out through a rather intense thunderstorm, so they got soaked.
Would it be best to remelt them and recast them to be sure there's no moisture in them anywhere?
