OK, beer turned black and so did the bearings.  Can I put them in to a zip lock and go that route or was that just a $30 experiment gone awfully wrong???   

Yes, but how did it taste?

Dude, it was nasty looking.  It smelled like liquid metallic pale ale.

Seems like a lot of work for something that has negligible benefit.

And really glad I posted and got your advice Jeff.  That would have ruined a good beer and a lot of hops.......

Whoa! Like I said not a metallurgist, but thought give it a try in a glass as an experiment just to see. Glad it saved you some angst over ruined beer.

You know me, I like to tinker!

I have one wrapped in water weld curing now.  Will try it out when I get home on Thursday.  Or maybe I'll just buy a handful of SS pipe fittings........or marbles.

52100 typically has a Cr content of ~1.5% - good for heat treating but doesn't do a lot for corrosion resistance.  Use a 304 or 316 stainless or a non-metal.....like marbles (any glass or ceramic will work too!).

I use marbles, a chunk of 304 stainless, or an old keg post that I snapped the pins off while trying to remove it.

BTW your beer turned black because the pH is low enough to etch the steel.  When steel is etched it turns...black.

When my company isn't paying me to answer emails and go to meetings I spend time being a metallurgist.

The wife is going to pick up more of the glass beads she uses to weigh down flower vases. Those are real cheap. One other usewill be to keep meads up to the neck of the carboy.

WOW!  Talk about the guy I was looking for in the title!  Thanks....

The Water Weld seems to have worked.  It's been sitting in beer for 3 days and it still smells and looks like beer!  It is non-toxic once cured so I think I'll wrap the other one and then vacuum seal them.  That should do the trick.
