Many info says that the rigth/best color after fuming with iodine is yellow with strong haze of pink/purple.
Is this color ( yellow with pink/purple haze ) to be reached at the end of the first fuming with iodine before fuming with bromine ?
Or is this color ( yellow with pink/purple haze ) to be reached at the end of the second fuming with iodine ?
I hope my question is clear enough … I normally do not speak english …
I mix liquid Bromine with silica gel. I try to get it bright yellow (“post-it” note yellow, if you have that product in your country). I’ve found that as the Bromine color heads into orange, it is too powerful.
I also heat my plates with a blow dryer before fuming to accelerate the chemical reactions.
