Step Date Type Process Changes #1 2010-04-01 mechanical Anorthosite rock has been crushed at mm scale rock in powder with mm grains #2 2010-05-01 thermal Anorthosite grains have been melted in high temperature furnace (Nabertherm HT17/16) at 1500°C for an hour. The furnace operates at oxidizing terrestrial conditions. Anorthosite grains melted #3 2010-05-01 thermal Anorthositic liquid has been quenched in air. Glassy Anorthositic solid is formed - Comments
- Glassy Anorthositic solid was produced at Volcanologist Laboratory with the help of Dr. A. Vona (RomaTre University)
