BB fuses with strong intumescence at 

 first, but afterwards quietly, and becomes 

 surrounded with a yellow glass. In the 

 inner flame fumes strongly, and yields a 

 white metallic globule. 



Soluble in concentrated muriatic acid, 

 with evolution of sulphuretted hydrogen. 



Locality. The Cobalt mines of Sweden. 



Name. After Von Kobell.
