Scan of first negative was posted to the new thread for glass plate negatives.
The unfixed emulsion shows in the scan as I have not cleaned it off yet.
After checking the plates this morning there is an area where the emulsion is very soft, one on each of the plates. The soft area is a swelling in the emulsion. It still holds detail but it sits just proud of the rest of the dried emulsion. It is soft enough to leave an impression when I touch it. The area is not connected with the minor edge frilling but is separate.
Not sure what to think of it or identify the cause. It is exposed, developed and fixed emulsion but it is soft and slight swollen up from the glass. Perhaps the hardener did not work in these sections?
Some details.
Developer is Legacy Pro L110 dilution b. This is a rebranding of HC110 by Freestyle. (6 minutes 15 seconds)
Stop is dilute vinegar. (1 minute)
Fixer is home mixed hypo with Legacy Pro hardener added in the tray. (4 minutes)
All chemicals mixed using distilled water.
Washed with gently flowing tap water. (6 minutes)
Temperatures ranged from 64F (developer) to 68F (wash water)
Trays are Paterson 8x10 plastic trays.
Agitation provided by slightly pushing the trays themselves at 30 second intervals.
Plates were moved only to transfer between trays.
Plates were held by edges.
