dlaery Posted May 25, 2018 Report Share Posted May 25, 2018 I buy pure lead with a analysis I think 99.9% lead. I looked at the analysis and it's all minute amounts of other stuff, I have bought a lot of this lead and usually mix antimony with it for spincasting, never blue I hand poured some jigs and they all turned blue. but it has been a long time since I've seen it turn blue but this is really bad. here's a pic of the cut off sprus anybody ever experience this?

Porkrind Posted May 26, 2018 Report Share Posted May 26, 2018 Nope, I can honestly say I’ve never seen lead turn blue like that. I’ve seen some other issues with lead nowadays but not the blue coloring. Really makes me question where I should source your lead from in the future.

stretcher66 Posted May 26, 2018 Report Share Posted May 26, 2018 it somehow oxidized, either by over heating or some type of zinc was introduced to it. Quote Link to comment Share on other sites More sharing options...
Slammingjack Posted May 26, 2018 Report Share Posted May 26, 2018 I have seem lead that was like a rainbow. Blue ,red or pink spots. It was darker than the other lead I had. Was told it was very pure lead. Maybe pure that has been cleaned. It poured real good and once it was painted look real good. Quote Link to comment Share on other sites More sharing options...
dlaery Posted May 26, 2018 Author Report Share Posted May 26, 2018 Wikipedia says " When freshly cut, lead is bluish-white; it tarnishes to a dull gray color when exposed to air" I don't have this problem (Blue) with scrap lead . the longer stuff sets the darker it gets. I wasn't going to paint this. Oh well. just curious other peoples's experience. Thanks, Quote Link to comment Share on other sites More sharing options...
