Subject: Diluting gelatin with alcohols
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.
