 Gelatin
Numerous references have been made here to the fact that modern gelatins are not the same as the gelatins used in the past for film and paper manufacturing. The so-called "activated" gelatins. Since film production only slowed down about five years ago, I am curious as to why the traditional gelatins used for film/paper manufacturing went away? I know that all modern manufacturers have, I guess, figured out how to use current gelatins, but why did they have to? When did the switch occur? |
