Paper for Cyanotypes - An (Incomplete) Survey

[cullah]

I did a slapdash, very non-scientific test of one of the orange papers this evening.

I have no idea if this happens when one is laying down too much sensitizer, but the middle of the sensitizer blob stayed a blob, while the outer edges which I had coated more thinly, showed up as blue when exposed to my UV lamp. I am not sure either if the cyanotype solution itself is acting up, since it is out of date.

I am going to do another test, and get the sensitizer on a bit thinner. Perhaps it is a matter of getting less on there, and keep off flooding it, since the solution just bled through to the back of the paper. Anyways, I enjoy the surface, and I'll keep at it for a bit to see if I can get it to work. If it doesn't work, I'll draw funny birds on it instead.

Socorro paper for pt/pd

Can you provide more information about this paper? Especially a source!

I tried Google to find out more and came up essentially empty, only a link to a 19 year old post here at Phototrio which mentions that it was supplied by Bostick and Sullivan. However, a look at the B&S website does not seem to mention "Socorro" at all.
