Re[2]: Natural Thorium

[michael_coogen@ccgw1.hq.dla.mil]

     Coleman Lattern Company has substituted another element in its lattern 
     mantles from the original thorium.  I regret I don't have there 
     address.  In addition I know that thoirum welding rods, in some 
     instances, are being modified and thorium is being substituted with 
     tungsten...Wish I could offer more..mike coogen
