grams of chees e
made from milk from which the cream has been remo e
equal to 93 grams

whole being mixed with 2 liters of water . Boil for three-quarters of a n

Take 1 kilo of sulphite pulp, 250 grams of china clay, t o
which has been added 3 liters of water, followed by 250 grams of starc h
which has been previously made into a paste with a liter of water ; the
mixture is then boiled and rubbed to a mass of uniform consistence .
This compound is preferred for the manufacture of architectura l
ornaments, a strong adhesive being made by soaking 250 grams of glu e
in 2 liters of water over night and boiling the mixture ; casein is prepared by treating 10 parts of dry casein and 1 part of soda ash with 4+ 0
parts of water . The addition of 15 percent of boric acid is recommende d
as a preservative . Casein is preferred to glue because it combines mor e
readily with the rosin and the resulting cement adheres more tenaciously .
It is on account of this that casein and rosin play such an importan t
part in the fabrication of papier mache .
The papier mache is molded into different forms according t o
requirements . The preparation of the plaster of paris molds calls fo r
some care and skill .
