Response to Pyrocatechin

from Garry D. Lewis (glewis@ftw.nrcs.usda.gov)
From the "Encyclopedia of Photography" pg.446-

Sodium tribasic phosphate is recommended by Messrs. Lumiere as an accelerator:-

A. Pyrocatechin 22g. Sodium sulfite 110g. water 1000ccs B. Tri-Sodium phosphate 14g. water 1000 ccs Add 1 part of each of A and B to 1 part water.

I've already E-mailed Ed a formula about a Pyrocatechin paper developer and noted to him that Thornton's DiXactol is a Pyrocatecin/glycin based developer. Haven't tried it, Yet.
