>no my washing water is around 15 dC.., I had the feeling that the
airbubbles were formed by some kind of chemical reaction between the
paper and or the Zia emulsion and the Citric acid (30g/ltr).<
I never try this paper but I will as soon as I find it .
I never see it on other paper I try.
it must be a reaction betwenn the acid and the buffer of the paper (perhaps
sodium carbonate)
