Hi Paul,

Manganese dust is also a problem.I knew a Potter in Toronto who used a  
black firing clay coloured with manganese. Hi whole studio was dark  
grey. He killed himself but I don't know why. I don't think there is a  
clay company in North America that sells manganese coloured clay any  
more.

Best to consider manganese in whatever form a danger.

Remember when they took lead out of gasoline? They replaced it with  
manganese. I don't know how long that went on but it was disallowed  
eventually.

One of the particularly sad things about manganese is - even though  
you stop exposure the symptoms keep getting worse.
