WARNING: what follows is based on fuzzy memory and is just designed to get someone more knowledgable out of the "woodwork": I think paste wood fillers usually contain some kind of binder as well as the powdered filler material. There are old formulae which include boiled linseed oil, etc., making a kind of sludgy varnish. Gypsum is a calcium sulfate, and related to Plaster of Paris. The old finishers used both, I think, and maybe calcium carbonate (chalk). I don't remember if they always used a binder, but one of the old finishing books might say, or maybe Stephen Birkett uses old processes and remembers. Bob Davis
