   It was a favourite experiment of my high school teacher of   
    inorganic chemistry.   
   It was not a burner, just a simple tube.   
      
   Burner may need adjustment due different gas ratio and viscosity.   
      
   The flame may need to compare side by side to tell the difference.   
      
   I do not remember anymore, perhaps there was different/reversed   
    flame zoning.
