From erythr- + -ite.


  • It combines with erythrite, forming another tannoid, erythrine.

    Synthetic Tannins

  • Under weathering conditions these minerals oxidize readily to form asbolite, a mixture of cobalt and manganese oxides, and the pink arsenate, erythrite or "cobalt bloom."

    The Economic Aspect of Geology

  • They with you, nullified you tips, spirant your damn erythrite, stillbirth you to meliorative new trail and flatboat.

    Rational Review

  • Cobalt produces the violet-red color in erythrite, (cobalt arsenic sulfide).
