Tin. 



The metal will not readily give a spectrum, but shows that of any volatile 

 impurity, such as lead, that may be present. Stannous chloride gives a 

 spectrum with great ease, and shows the principal continuous lines of the 

 spark spectrum of tin with brilliancy. On the introduction of a condenser 

 the lines of chlorine come out, and many of the discontinuous lines of the 

 spark spectrum of tin are also seen.
