I mixed up some fresh Gerry Collodion yesterday.
from Facebook....
The Gerry Collodion (or whatever it’s original name is) changed color and passed the QQC collodion in darkness, in only 1 day. GC 24 hours old, QQC about 3 days old. The iodide salts are really working! No added ether, wonder if that makes a difference. Last year GC took a long time to turn red. Will follow its progress this year.
About 23 hours or so later, has turned from yellow to orange. |
