Ikaite - Wikipedia

Ikaite is the mineral name for the hexahydrate of calcium carbonate, CaCO 3 ·6H 2 O. Ikaite tends to form very steep or spiky pyramidal crystals, often radially arranged, of varied sizes from thunail size aggregates to gigantic salient spurs. It is only found in a metastable state and decomposes rapidly by losing most of its water content once removed from near-freezing water.
