Formation Aid (Neri, Tororo-aoi, Mucilage)
Formation Aid (Neri)
(Pronounce Torro O Owee) |
Reason for
Formation Aid ( Neri):
- It is essential when using the Japanese fibers and can be used with
Abaca to form a thinner sheet.
- It separates the long bast fibers and slows drainage.
- Better distribution of fiber
- Allows for multiple dips.
PMP Formation Agent is used in Nagashizuki (Japanese style)
papermaking.
- Strings from hand
- It is a synthetic substitute for the tororo-aoi plant. Originally
from root of hibiscus
|
Natural Substitutes |
- Fresh or frozen okra pods (Nash also said ?aloe vera?)
- Prickly pear cactus
|
Preparation of Okra for Formation Aid |
- Slightly crush fresh or frozen okra
- Wrap in cloth (muslin) and fasten top with string or rubber band
- Put bag in a quart of water. Let sit for 1/2 to 1 hour
- A clear gelatinous material will ooze out of pods.
- It is preferred to squeeze the gelatinous material in the bag
directly into the vat.
- The water from the soaking may also be used

Mixing Instructions (PMP)
- Mix 1 gram (1/4 teaspoon) of Formation Agent with 1 liter (1 quart)
of cool water,

- Mix intermittently in a blender.
- Slowly run water into 1 quart jar (spray nozzle preferred)
- Gradually sprinkle 1/2 to 1 teaspoon into the water
- Stir vigorously.
- Let stand for 8 hours.
- One teaspoon makes a thick solution that usually needs to be thinned
before use.
- After 8 hours pour apx 4 oz. Into a jar and add apx 2 oz of water
- Add apx same amount to the parent jar.
- Always stir the formation aid before use.
- If not dispersed in slurry you will get thin spots or "jelly
spots" in paper
Store mixture in refrigerator. In powder form, it will not spoil or lose
effectiveness for at least one year.
