Re: I'm back! Hi to all + Silane?
Hi Katharine, I found your correspondence with Martin Mueller here: http://www.usask.ca/lists/alt-photo-process/2005/mar05/0088.htm I will do few things different: First, the sources I could find about glass silanization (mostly medical, about preparing glass or mica dishes for culture growing ect., looking for better adhesion of organic molecules onto the glass) say one should *rinse* the glass after a *timed* dip into the solution. Second, I will put a hardened gelatin *subbing* layer between cyanotype/gum layer and silanized glass. I saw no evidence that you did these in your description (probably because Martin hadn't mentioned). I feel more positive about cyanotype, I have doubts about gum (since even silanized and primed with gelatin, the glass will have very little tooth - it any - for gum). We'll see if I ever manage to try this in a couple of weeks.
