Title: Arsenic and manganese use for decolourising
Post by: Adam on August 02, 2007, 08:53:55 PM

Angela - You didn't mean to suggest that arsenic was not used after c 1940 and manganese (for decolourising) after 1930, did you?  Both were still being used long after WW2 and, for all I know, still are.

I think I've made this comment before, but goodness knows where!

Many thanks, Adam, for pointing this out.  I have changed the text to make this clearer (http://www.glassencyclopedia.com/irradiatedglass.html )
