The radioactivity of thorite often brings it to a state of metamiction, in which its crystal structure becomes unstable thereby causing the crystal edges to become smooth and rounded. When this happens, the thorite may gain hydroxyl (OH) molecules in place of the silica (SiO4) molecules and transform into a different mineral, thorogummite. 3, record 1, English, - thorite
