The tools required for making this vase are the same as those used
for the bowl, and the process of building is much the same. The chief
difference is that it is more difficult to preserve the profile in
building because the added height and the greater weight tend to
bulge the lower part. To meet this difficulty it will be necessary to
set the work aside quite often in order to let the lower part harden
sufficiently to support the upper part.
_The Profile._--In preparing the profile the same rules hold as were
applied in working up the problem of the bowl. It will be well to
remember, however, that the curves of a vase must be treated with
greater reserve as to their lateral projection than was necessary in
the case of the bowl--_i. e._, the curve of a vase should be enclosed
within a rectangle narrower in comparison with its height than is the
case with the curve of a bowl. The reason for this, of course, is found
in the greater height of a vase in comparison with its diameter. The
following figure shows three typical vase forms. If these curves be
compared with those shown on page 288, illustrating bowl contours,
it will be observed how the height of the vase is emphasised in the
greater restraint and subtlety of its curves. In the next illustration
we have two "horrible" examples to which attention has already been
called in the suggestions for the design of bowls. The dotted lines in
the illustration show how these curves may be improved if, in either A
or B, one element of the compound curve be made dominant at the expense
of the other. If at the same time the diameter be made smaller in
comparison with its height the attractiveness of the contours will be
still more improved. Indeed, it will be a transformation from a profile
that is positively bad to one that is very good.

_Decoration._--The problem of decoration is not very different from
that of the bowl. Here again, however, the added height seems to call
for greater accent by means of vertical or panel divisions. Unless this
be understood there is some danger that the larger vertical spaces will
seem to offer simply more room for horizontal bands, resulting in a
barber pole effect.
_Handles._--If handles or buttresses are desired, care should be taken
that they are designed as an integral part of the vase--_i. e._, that
they continue or reinforce its lines. Two suggestions for the treatment
of the problem of handles are given in the accompanying drawing.
It will be noted how sympathetically these handles conform to the
lines of the vases to which they are attached. Handles that give the
impression of being made for another vase should be avoided.
