baking enamels, cores and colOred inks on litho-
graphic plates. The japan baking oven has been
developed from the experimental stage in the last
four years. The process Of baking japan In fuel
burning ovens, owing to the fact that volatile and
explosive liquids, such rs naphtha and kerosene,
are used as solvents, has always been n some
what hazardous operation. The gases given of
are Of a highly-explosiye nature, and frequently
these ovens have exploded with decidedly disas-
trous results. Another fault of this fuel oven was
that in baking the lighter colors of a japan or
enamels, SCOT from the gas sometimes would dis
color the baking articles. Some of the ovens used
in this work are of the conveyor type, SO that
loads can be loaded and unloaded while one Is
baking. The capacity of two of these ovens used
In one plant is greater than that of six gas-heated
ovens, formerly used to do the same work. 1t
takes about three-quarters of an hour to com
plete a baking in one factory where these ovens
are largely used, which more than doubles The
number Of loads finished per day, with a saving
of 20 cents per load, which ran up into thousands
of dollars when figured on a daily basis. The
quality Of work turned out is superior TO that Of
the old type; it requires little or no attention,
and the fire hazard is largely eliminated.
1t is interesting to know that a new type Of
japan is being developed which consists of an
emulsion Of the asphalt base with water, thus re-
moving the fire hazard, besides being much clean
err to handle. This process is called water japan.
Ovens are used for many other purposes; steri-
lizing dental instruments, baking effervescent
salts and drying all sorts of products requir-
ing well-regulated heat and a clean atmosphere
i'm the oven itself. The fact that their tempera-
lures can be so exactly regulated, the absence Of
a mass of fuel-carrying pipes, fumes, SCOT, and
other by-prOducts Of burning gases, make the
electric oven theoretically ideal for this purpose.
The fourth process mentioned, electric sherard-
izing, is a patented process for protecting exposed
iron parts from corrosion due to exposure to the
weather.
Besides ovens, furnaces, and other devices men
toned, there are a number of small "indiyidual'
Acknowledgements pots, furnaces, ETC., for use in
the shop, garage, or even Mt home. In this class
are compound melting pots, glue pots, metal melt
ers. small furnaces and electric soldering irons.
Many of them are easily portable, in fact
can be attached to almost any lighting or shop
circuit. For work in a book bindery or pattern
shop for instance, the electrically-heated pot keeps
the glue continuously at just the right tempera-
ture for use, but never burns it; the same may
be said Of the compound melting pot and the lead
or 3abbitt melter, which are ideal for work around
a garage or in a factory. AS for the soldering
iron. anyone who has used the gas-heated type on
top of q ladder or in some inaccessible place, need
not be told the advantages Of an iron that is al
ways hot and still light and we'll balanced enough
to be used with accuracy and comfort
In spite of it's growth in the last few years,
the application of electrical heating to industry
is only in it's infancy. The time will undoubtedly
come when the effort to conserve our natural coal
and gas resources will cause 1t to assume much
larger proportions. There is generally no limit
to its possibilities of development not only as
applied to factories, but in offices and homes. En-
gineers say that the saving Of floor space, cleaner
and more healthful working conditions, to say
nothing of the improved speed of production and
superior quality Of work done, all tend to make
its universal adoption but a matter Of time
and comparatively short time.
