Indochinites were ejected into the Earth's upper atmosphere by a huge meteorite impact 788.000 years ago in the Gulf of Tonkin (Vietnam). The steam jets cooled down in the higher atmosphere and condensed to form this type of glass. The pieces rained down hundreds and thousands of kilometers away from the impact, in direction South-East, reaching Philippines and even Australia. They have diverse shapes and a characteristic black color.
