Wheatpaste

Wheatpaste is a cheap and non-chemical based glue used in pasting up posters, or in papier mache, for model making.

[edit] Wheatpaste Recipe

You need:

take 3 tablespoons of flour in a bowl;
add cold water and stir, until it's a runny mix;
put one cup of water in your pot, heat it until it's almost boiling.;
put the cold wheat-water-mix in it slowly while stirring constantly with the beater/fork (leave the pot on the hot plate while doing this);
bring to boil (just for a minute or so) ;
keep stirring!!

if you want, you can add a tablespoon of (white) sugar while it's still hot, for extra strength.

You need:

hot plate (stove top) and a double boiler
stick mixer (an electric hand-held blender thingy)
wheat flour (plain white)
water
spatula
a hermetically sealed container (a plastic container will resist the shocks of being transported and bumped down onto concrete and macadam footpaths)

combine flour and cold water (1 part flour to six parts water by volume) in the top of the double boiler off the stove;
beat the mix until it is smooth and completely lump free;
partly fill the bottom of the double boiler with hot water;
put the top of the double boiler on the bottom and place on the stove and turn the heat on;
mix the wheat paste mix frequently with the stick mixer;
the wheat paste mix will slowly come up to a simmer and clarify;
keep beating the mix as it will tend to cook from the bottom and thicken unevenly and form lumps otherwise;
when fully cooked, take the top of the double boiler from the bottom off the stove and beat occasionally as it cools (otherwise you will get a skin forming on the top);
you will find that the consistency of the paste thickens somewhat as it cools down;
use the spatula and pour the mixture in a hermetically sealed container and store it in the refrigerator;
the wheat paste can stay useable for up to a year if stored in the refigerator.
