It will be about 5 stops slower than a modern enlarging emulsion. It will develop nicely with either Dektol or an Amidol developer.

If made, the coating should be carried out in about 5 - 10% gelatin with a surfactant and a hardener. The emulsion should keep for 6+ months in a refrigerator, and the coatings should keep for at least one year.

Not all of the emulsions in that book have been tested, but I do recommend it. It is a very good introductory book on the subject.

thanks - I'll give it a try.

What does surfactant mean? never heard that word before...
