Lith chemistry questions

Tim, I was wondering if you’d be willing to comment on the role of two other
chemicals that are typical in the makeup of Lith developers, paraformaldehyde
and alkali’s.  

Could, or would, you briefly outline the use of formaldehydes, either
paraformaldehyde, or sodium formaldehyde bisulfite and would you comment on the
use of different alkali’s and/or their combinations and the result they might
have on the process of lith development?  

(Thank you for your comments on image degradation.)
