Summary

Description	English: Bismuth crystal. Bottom front edge has a length of about 3.5cm. Iridescent colour is created due to interference effects in a thin oxide layer, which forms when the hot crystal is pulled out of the bismuth melt. Español: Cristal de Bismuto. El borde frontal inferior tiene un largo de aproximadamente 3.5cm. El colour iridiscente es creado debido a efectos de interferencia en una capa delgada de óxido, la cual se forma cuando el cristal caliente es sacado del bismuto derretido.
