PASTE
A paste must be used with the colour in order to hold it on to the surface of the paper and to give brilliancy. The colour, if printed without paste, would dry to powder again. The paste also preserves the matt quality which is characteristic of the Japanese prints.
Finely ground rice flour may be obtained from grocery dealers. An excellent French preparation of rice sold in packets as Crême de Riz is perfect for the purpose of making paste for printing. It should be carefully made as follows: While half a pint of water is put to boil in a saucepan over a small spirit lamp or gas burner, mix in a cup about two teaspoonfuls of rice flour with water, added little by little until a smooth cream is made with no lumps in it. A bone spoon is good for this purpose. Pour this mixture into the boiling water in the saucepan all at once, and stir well till it boils again, after which it should be left simmering over a small flame for five minutes.
When the paste has cooled it should be smooth and almost fluid enough to pour: not stiff like a pudding.
While printing, a little paste is put out in a saucer and replenished from time to time.
Fresh paste should be made every day.
