Re: Masa in sulfuric acid


Try looking at some of the Japanese papers that are used for the Chin Cole method of printmaking—some of them are very translucent, almost like real onion skin.

As you can see, Masa treated in sulfuric acid isn't more translucent than
unprocessed Masa. The color is different (much much warmer and/or whiter -
bleaching?), the surface is different. (More textured - due water
processing or acid processing or both I'm not sure.)

Case closed. Verdict: I should have been concentrating on finding already
translucent paper instead of produce one! ;)
