in these very rare circumstances where gas is not available, the stove
can be heated with coal or wood, which will, of course, involve a
total alteration in the structural arrangements. I have not given the
details here, as I do not think the necessity will ever arise for
their use, and for the same reason I have refrained from giving the
particulars for heating by steam and electricity, or the other methods
which have been adopted by various workers, as there is no question
but that a gas stove or oven, as described, is about the best and
handiest for jobbers or amateurs.


MODERN JAPANNING AND ENAMELLING STOVES.

The modern japanning and enamelling stove consists of a compartment
capable of being heated to any desired temperature, say 100° to 400°
F., and at the same time, except as regards ventilation, capable of
being hermetically sealed so as to prevent access of dust, soot, and
dirt of all kinds to mar the beauty and lustre of the object being
enamelled or japanned. Such a stove may be heated--

1. By a direct coal, coke, wood, peat, or gas fire (which surrounds
the inner isolated chamber) (Fig. 5).

2. By heated air.

3. By steam or hot-water pipes, coils of which circulate round the
interior of the stove or under the floor.

Such ovens may be either permanent, that is, built into masonry, or
portable.
