I don't know what liquidol really is, and there's no information on the web.
The MSDS says it's a water solution with sulfite and hydroquinone, looks like a little less hydroquinone than dektol. Does it have metol in it like Dektol or does it have phenidone? I assume that since it's based on water and not glycol like HC-110 that there is something in there to prevent oxidation but they aren't saying so. With that extra sulfite in there I am assuming it's going to be a little more compensating than dektol, if it's using metol, and it'll be a whole lot more compensating if it's using phenidone. This would probably be more noticeable if you're using it for film processing than paper. Anyway... if you are worried about students mixing powder compounds poorly, you could just premix the stock solution for them and hand it to them. Or you could make a super-concentrated solution with a little glycol and let them mix down from that. I'm curious why you're using a paper developer instead of ordinary D-19, though. D-19 will definitely give you finer grain. --scott _______________________________________________ FrameWorks mailing list [email protected] https://mailman-mail5.webfaction.com/listinfo/frameworks
