layer of clear varnish only, to add to the lustre.

Care must be taken for light-coloured japans or enamels not to have
the temperature sufficiently high to scorch, or the surface will be
discoloured, as they require a lower temperature for fixing than the
dark japans, which, provided the article is not likely to be injured
by the heat, are usually dried at a somewhat high temperature. The
preceding instructions apply only to the best descriptions of work.

When pouring enamel by means of the ladle over pieces of work, do not
agitate the liquid too much--at the same time taking care to keep it
well mixed--so as to form air bubbles, as this will cause trouble, and
in pouring over the work do it with an easy and gentle and not too
hurried a motion. In japanning curved pieces, such as mud-guards,
etc., in hanging up the work in the oven see that the liquid does not
run to extremities and there form ugly blots or blotches of enamel.

When white or other light tones are used for japanning they are mixed
with japanners' varnish, and these require more careful heating in the
oven or stove than darker tints or brown or black.

[Illustration: FIG. 1.--Trough for Dipping Bedstead Frames and other
Large Work.]

ENAMELLING BEDSTEAD FRAMES AND SIMILAR LARGE PIECES.

At Fig. 1 is shown a trough in which large pieces, such as bedsteads,
bicycle frames, etc., are dipped or immersed. For the first-mentioned
class of work such high finish is not required as for bicycles, and
consequently the enamel need not be applied with a brush, nor will it
be necessary to rub down the work between each coat, but instead the
pieces can be literally dipped in the tank of liquid, then allowed to
drain on to the dripping-board--the superfluous enamel thus finding
its way back into the trough or tank, the dripped articles being
afterwards placed in the oven to harden. The trough must be of
sufficient dimensions to allow the pieces of work to be completely
immersed, and the dripping-board should be set at an angle of about
45 deg..

Bedstead frames will never require more than two coats and the
commoner class of goods only one. I would not advise the tradesman in
a small way of business to go to the expense of a trough, etc., as it
calls for much more room than is ordinarily available, but if he has
the necessary plant for bicycle work he can, of course, do an
occasional job of the other kind.
