Pica glass was probably formed when an asteroid or comet hit the surface of the earth like a huge atomic bomb. The surface was partially or totally melted forming the glass.
Pica Glass contains abundant silt-sized and finer meteoritical particles that occur as individual phases and complex assemblages typically associated with vesicles [2,3]. They range from buchwaldite (NaCaPO4), Ni-bearing troilite (FeS), and oldhamite (CaS) to rock fragments composed of Mg-Fe silicates, corundum-bearing perovskite (CaTiO3), and serpentin-ite.
Here we offer a nice specimen of the Pica glass of 71 grams.
