The oil is filtered, given its proper consistency liy tlie addition
of pure hydrogen and tiien sterilized by \ery liigli heat. Nothing
but hydrogen is added to the oil to gain this consistency essential
to the easy and proper combining of Crisco with flour and sugar.
This hydrogenizing process is respon.siblc for the peculiar vir-
tues of Crisco. Crisco is what is known in chemistry as a .synthetic
product, i. e. "a fat made to order." This makes it possible so to
govern the ])rocess of hydrogenizing that the resulting protluct shall
have fewer faults than a natural ]>roduct. .V cooking fat made by
this process, such as Crisco, has less teridency to become rancid,
to smoke when heated and give off strong odor. And the true
shortening components are present in greater percentage. The
details of this hydrogenizing process are controlled exclusively by
The Procter &; Gamble Company.
THE CRISCO BUILDING

The Crisco building, devoted solely to the preparation f)f Crisco,
is a handsome, modern structure of rugged stone and brick. It
stands quite alone within spacious grounds tliat during the rest
hours are used for tennis and other outdoor recreations.
The vast rooms are walled with glass and flooded by sunlight
which shines through windows that never need be oj)ened, for the
air in circulation throughout the factory is water-washed; driven
into the rooms dust free and germ free-l— pure. Every employee
is dressed in white. Daily changes of clothing arc made.
The floors of the Crisco building are of terrazzo. Pillars, ceil-
ing and refrigerating timnels are of white tile. Corners e\'erywhere
are rounded to make constant cleaning a simple matter.
