 I have been using gelatine for sizing for gum prints, albumen platinum, salt
prints and cyanotypes and kallitypes and for making carbon prints for for
thirty years. In fact I bought 25 kilos of the last of Croda Colloids
manufacture of 160 Bloom deionised ossein, photographic gelatine, to make sure that I
had a good supply of the good stuff for my students, my friends and myself.

So we agree that gelatine is good.

Gelatine is less expensive and it is less trouble but you are in no position
to say that the results are just as good as collodion or albumen sizing for
platinum printing as you have never done it or seen it done..So don't knock it.

I can assure you that an albumen sized platinum print gives a good result
that offers a difference that justifies the extra trouble and expense and that a
collodion/platinum print offers such an improvement that it is in a completely
different class. I am not going to repeat the list of its advantages here. I
suggest that you come to the conferences in Oxford, Rochester, Pittsburgh
(where there will be workshops), and perhaps Santa Fe and to exhibitions in
Teddington and Croydon where you can see and hold the things so that you are in a
position to judge for yourself.

We also seem to be agreed that yellowing can occur in albumenised paper when
no silver is pesent, and in this case it is a real problem, even though you
may not have experienced it.
