Re: My own PVA glue sizing experience became: dark reaction in gumemulsion
didn't the emulsions seperate? not even after a week? or did you keep agitating in some way?
any time i keep a mixed gum emulsion, the pigment sinks to the bottom after a day or so. it looks like if it's the pigment/gum sludge at the bottom and the dichromate on top.
