Mystery metal grains? Cobalt?
Found a few lbs of it in an induction furnace that I bought for $30...
Pictu https://www.machinerymoverschicago.c...tery-metal.jpg These are oxidized metal grains. The oxidation color is bluish and most closely resembles blueberries, though I am somewhat color blind. Any idea what this metal is? Could it be cobalt? |

Steel turns blue when heated. https://www.anvilfire.com/article.ph...s_hardness.htm http://staff.buffalostate.edu/nazareay/che112/ex9.htm NH4SCN is ammonium thiocyanate. A simpler test is to dissolve a little in hydrochloric acid, dry the solution over heat (acid fumes!), and see if it turns blue. You could neutralize the acid by adding garden lime or baking soda until it stops fizzing. I don't know if other metals would interfere. https://en.wikipedia.org/wiki/Cobalt(II)_chloride |

Definitely not copper, when ground down they look dull grey. Not magnetic. |

You really need to splurge and treat yourself to one of those handheld x-ray fluorescence machines. No more guessing on mystery alloys or things like these beads. You could even do analyses for scrapyards and pay it off even sooner :-). -- Regards, Carl Ijames |

Koslow Scientific https://www.koslow.com/ has all sorts of metal ID kits. You may want to check them out. Disclosu I do a lot of electronic design work for them, but don't make any extra money from sales. |

Cobalt is ferromagnetic, so unless it is fully oxidized, it would be magnetic. Jon |

And the local scrap yard has one already. But if you send me one of the buttons I will try talking one of the guys into scanning it. Dan |
