I recently acquired a copy of Tim Rudman's 'The Master photographer's Lith Printing Course' & tried out the sodium hydroxide enriched developer process (pg 100 if you have a copy).
I followed the method identically. I added 5g of sodium hydroxide to Ilford PQ (diluted 1:19), mixed well & maintained 20 deg temp throughout the testing.
I began with Ilford MG V RC which, being RC, I appreciate probably isn't a great choice for this purpose, but it allowed me to do a quick test & also this paper has reacted favourably in other processes (Selenium, sepia etc.). Nothing different happened other than slower development. I moved to Ilford FB gloss (the actual paper used in the book); again nothing happened any different from standard developing.
So I tried adding more sodium hydroxide, adding 5g, testing, adding a further 5g, testing again & so on; this again changed nothing. As a last resort I tried diluting the developer even further, again this didn't work.
So now I am puzzled, I would really like to get this to work successfully. The only thing I can think of is that Ilford FB has since been updated & no longer works for this purpose. I'd love to hear any suggestions before I try buying another brand/type of paper to experiment with.
