FIRST FOUNDED

I’m foundI was first founded in a mine in Germany When Winkler was examining argyrodite It was called the Himmelsurst mine near the town

of Freiberg

FORM

Organic form53 different forms

Inorganic formSalts and oxides lacking germanium carbon bond are correctly categorized as inorganic forms.Regular form
