baking enamels, cores and colored inks 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 as naphtha and kerosene,
are used solvents, has always been some
what hazardous operation. The gases given off
are of highly-explosive 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 japan
enamels, SCOT from the gas sometimes would dis
color the baking articles. Some of the ovens used
in this work of the conveyor type that
loads 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 threequarters of an hour to COM
pete baking in one factory where these ovens
largely used, which more than doubles the
number of loads finished per day. with saving
of 70 cents per load which up into thousands
of dollars when figured a daily basis. The
quality of WORK TUNED out is superior 70 that of
the old type; it requires little or no attention,
and the fire hazard is largely eliminated
1t is interesting to know that 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 used for many other purposes; steri-
lizing dental instruments, baking effervescent
salts and drying all sorts of products requir-
ing well-regulated heat and clean atmosphere
in the itself. The fact that their tempera-
lures Gamble so exactly regulated, the absence of
a mass of fuel-carryng pipes, fumes, SCOT and
other by-products of burning cases. make the
electric oven theoretically ideal for this purpose
The fourth process mentioned, electric sherard-
izing, is patented process for protecting exposed
iron parts from corroson due to exposure to the
weather.
Besides ovens furnaces and other devices men,
toned, there are number of small "indvidual"
eectrcally-heated pots, furnaces, etc. for use in
the shop garage, even at home. In this class
compound melting pots, glue pots. metal melt
ers, small furnaces and electric soldering irons
Many of them are easily portable In fact
be attached to almost any lighting or shop
circuit. For work in book bindery or pattern
shop for instance the electrical y-heaed pot keens
the glue continuously at just the right tempern-
ture for use. but never burns 1t; the same may
be said of the compound melting pot and the lead
or sabbitt meter, which are ideal for work around

iron, anyone who has used the gas-heated type on
top OF ladder or in some inaccessible place need
not be told the advantages of an iron that is nj
ways hot and still light and well balanced enough

In spite of its growth in the last few wears.
the application of electrical heating to industry
is only in its infancy. The time will undoubtedly
come when the effort to conserve our natural coal
and gas resources will cause 1t to assume mucb
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
