From where have you your recipie?
I have never heard og adding any acids to the bromoil bleach... (unless I am from Denmark, and not understanding anything...)
I use (from memory): potassium bromide - copper sulfate and potassium dichromate...
(My recipie is slightly different than the one ex Gene Laughter uses, as I am doing this using liquid emulsions as matrix'es and not "normal" paper (can't seem to get it to work)
Care should be taken with especially the dichromate! (don't inhale - drink - eat - touch it... - use it in a well ventilated place. AND when disposing it - don't pour it in the sink... it is very damaging to the water inviroment...)
