COVER: Wire silver with calcite from Kongsberg, Norway (7 cm tall). Wire silver is the first known example of mineral growth by solid-state ion conduction in nature. See “Natural solid-state ion conduction induces metal isotope fractionation” by Anderson et al., p. 617–621. Specimen from Dave Bunk Minerals.
