Under certain conditions, precipitation of barium carbonate in alkaline silica-rich environments affords unusual polycrystalline aggregates exhibiting curved shapes and hierarchical structuring, very much reminiscent of biogenic mineral tissues. The formation of these so-called silica biomorphs is thought to rely on
