Hi all,

A question, in Gum dichromate, and exposing with UV light and then  
washing it, does this remove the dichromate out from the material  
I know with potassium metabisulphite it removes the yellow stain, not  
sure if it actually removes the dichromate?

An idea was to try using an glass enamel paint, and print on copper.  
Once its done put it in the kiln. Though with the dichromate still  
lingering on the piece, and adding heat to it through the kiln, the  
dichromate fumes is what scares me, I wouldn't want to be anywhere  
near! :)
