  1. It might be a broken septarian nodule.
     

    It’s possible a septarian formed and was eroded out of where it formed, then ended up in a stream bed or other placer deposit where it became part of a conglomerate. At some point It would have eroded out again and broke, exposing the softer calcite lining the center, which would have then eroded quickly. The bits on the inside would be the only remnants of what was once the interior.

    I think it’s long shot, but it’s possible. I think it’s pretty likely that it was once a concretion of some type, but not necessarily a septarian.

  2. Next weekend I’ll be participating in the Distinguished Gentleman’s Ride. It is a men’s health fundraiser, raising funds mainly for testicular cancer and mental health research.

    I know it’s been a tough year+ for all of us, and many of you are not in a position to donate. I’m okay with that sand I get it. If, however, you are wiling and able to sponsor me, you can do so here.

    I know tool steel is alloyed with nickel but I have no idea why your test didn't show it. Or if the tools you tested were alloyed with nickel. 

    It's worth experimenting though. No matter how many eye rolls you get.

    I hope you have some irons. That would be awesome!

    A lot of tools are chrome plated to prevent rust. That could prevent nickel from reacting with the reagents.
