Alex Nanson asked:
<I am particularly interested in the idea of adding starch to the gelatin in
order to impart 'tooth'. I notice that you state that the starch should be added
as a solution. Does this mean that as the gelatin cools the starch comes out of
solution and
forms a dispersion of fine particles within the gelatin layer?

It occurs to me that an alternative to starch, would be one of the fine silicas
or other such fillers that are used to reduce the gloss of surface coatings.>

This formula I mentioned is rather old but was used until some years ago with
good succes. I haven't tried other silicas but at the moment I see no reason why
it shouldn't work. No idea how much you would have to add of those substances,
but probably less then for an ordinary semi-matte silver bromide emulsion.

Good luck and please let me know how it works.
