Drying out...

This is one of the three plaster neckrings drying out.
The final rings were quite strong and I was able to pick them up off the baseboards and stack them.
After a little 'finishing' with fine sandpaper, they were sealed with G4 sealer.

Care had to be taken with the sharp outer edge, as it was quite
fragile and could easily have been chipped at this stage.
