Ruthenium, rhodium, iridium, osmium, tellurium, selenium, and antimony can also change you bead. Rhodium hates gold and so forms swirls in the button. Iridium makes a rainbow under the bead. Osmium, tellurium, ruthenium, selenium and antimony can ruin your beads by making them so brittle one mistakes them for glass.

The U.S. today is almost entirely reliant on China for its supplies of antimony, a rare earth mineral that is essential to the success of wind power, solar power and the next generation battery ...
Global conflict and fractured supply chains have strained U.S. ammunition supplies. Grants will be used to evaluate if antimony samples from the Stibnite Gold Project can meet military ...
For example, the production of low level arsenic- and antimony-containing anode copper could be generated by the use of sodium carbonate based slags. Sodium carbonate flux could reduce arsenic and antimony levels in the anode copper to levels under 0.01 and 15 ppm, respectively, if proper processing
