Diluting gelatin with alcohols

From: Cheryl Jackson <cheryl.jackson<-at->

I have been trying to dilute a 10% W/V aqueous solution of gelatine
with ethanol or isopropyl alcohol (down to 2%) without success. It
keeps turning stringy and opaque.

Should I be using a different grade of gelatine?

The solution will be used to consolidate a flaking gelatine emulsion
back down onto its glass plate.
