City of Bismuth in glass box on brass base
PUMI1679-1
This rectangular glass and brass display makes you want to dive into this artefact man-made but from a natural ore, not concentrated enough in nature to see such crystals: Bismuth. A crystal achieved by heating up to 270 Celcius degrees some bismuth ore and waiting that they slowly grow with this crazy shape, cooling down.A bit like an Inca city. This is the largest crystalisation that can be made of this metal.
