What is the purpose of the alcohol? Something like that in my darkroom could only lead to problems and memory loss. I have diluted the mix with distilled water to smooth out the coating and it seemed to work well for me but I wonder if the alcohol would work better? Or is it more of a surfactant and aid in blending the solutions.

Thanks for the article; Iíve been trying to dial in my gum printing for that very purpose.
