Yamato Nori is a water-reactive starch medium that can occupy several roles simultaneously.
Closer to refined rice/wheat paste than to synthetic white glue.
What it really is
Usually:
- starch
- water
- humectants/preservatives
Texture:
- gelatinous
- elastic
- translucent
- tacky when wet
- flexible when dry
Very Japanese-paper-craft oriented:
- origami
- collage
- conservation
- children’s craft
- paper layering
It behaves more like a controlled starch gel than modern PVA.
