Moulding (architecture)

“ In short, it may be asserted, without fear of contradiction, that in no style of architecture has a system of moulding been generated so full of variety and so capable of suiting itself to every position; and not only to provide for the practical demands of each position, but to give to each just that kind of effect which it most demanded. ”

“ All good ornament and all good architecture are capable of being put into short-hand; that is, each has a perfect system of parts, principal and subordinate, of which, even when the complemental details vanish in distance, the system and anatomy yet remain visible so long as anything is visible; so that the divisions of a beautiful spire shall be known as beautiful even till their last line vanishes in blue mist, and the effect of a well-designed moulding shall be visibly disciplined, harmonious, and inventive, as long as it is seen to be a moulding at all. ”

“ And with that a peculiar accuracy; for the mass which bears the light in this moulding is not in good Greek work, as in the frieze of the Erechtheum, merely of the shape of an egg. It is flattened on the upper surface, with a delicacy and keen sense of variety in the curve which it is impossible too highly to praise, attaining exactly that flattened, imperfect oval, which, in nine cases out of ten, will be the form of the pebble lifted at random from the rolled beach. Leave out this flatness, and the moulding is vulgar instantly. ”

“ FIG. 129.Towards the end of the twelfth century the sloping surface was sometimes given to the upper member of interior strings, whether in a spirit of conformity with the changed form that had been adopted in outside mouldings, or for other reasons, it is, of course, impossible wholly to determine. Perhaps the earliest instance of an interior moulding of this form is that of the triforium string of the nave of the Cathedral of Paris (Fig. 120") . The slope has not, of course, the same raison d'être here that it has when the moulding is exposed to the weather ”

“ But mouldings mitred on the solid had almost entirely replaced the older form of stopped mouldings by the end of the sixteenth century. By returning to the illustration of the screen at Haddon (Fig. 135) , an example may be seen alongside the heavier Gothic work; and another example, with a much deeper and broader moulding, may be seen in an upper room at the same place (Plate XLI.) . It is a provoking characteristic of work of this time that its method of treatment does not give an infallible clue to its chronological sequence. ”

“ We must, however, do the late builders the justice to note that, in one case, the habit grew out of a feeling of proportion, more refined than that of earlier workmen. It shows itself first in the bases of divided pillars, or arch mouldings, whose smaller shafts had originally bases formed by the continued base of the central, or other larger, columns with which they were grouped; but it being felt, when the eye of the architect became fastidious, that the dimension of moulding which was right for the base of a large shaft, was wrong for that of a small one, each shaft had an independent base ”

“ The Pier-arches, therefore, are almost invariably pointed, in [Pg 23] the earlier examples obtusely, and in the later examples often acutely; the mouldings, which have become much lighter, are few and plain; carrying usually a roll, or a pear-shaped moulding, at the angle of each order of the arch: they frequently have no Hood-moulding. All the usual rich ornaments of the Norman Style disappear, but the Chevron occurs occasionally, and another ornamental moulding somewhat resembling it, but peculiar to this Period, is frequently seen. ”

“ Another feature common to all phases is the use of round mouldings, either one by itself—often forming a kind of twisting broken hood-mould—or of several together, when they usually form a spiral. Such a round moulding has already been seen forming an ogee over the windows at Sempre Noiva and over the chapter-house door at São João Evangelista, Evora, and there are at Evora two windows side by side, in one of which this round moulding forms a simple ogee, while in the other it forms a series of reversed curves after the true Manoelino manner. ”

“ Not yet to be checked, it pushes forward until the roll itself becomes subordinate to it, and is finally lost in a slight swell upon its sides, while the concavities have all the time been deepening and enlarging behind it, until, from a succession of square or cylindrical masses, the whole moulding has become a series of concavities edged by delicate fillets, upon which (sharp lines of light, observe) the eye exclusively rests. ”

“ The crowning member of the cornice is a partly hollow moulding, technically called a “cyma recta,” less vigorous than the convex ovolo, of the Doric: this moulding, and some of the bed mouldings, were commonly enriched with carving. Altogether more slenderness and less vigour, more carved enrichment and less painted decoration, more reliance on architectural ornament [107] and less on the work of the sculptor, appear to distinguish those examples of Greek Ionic which have come down to us, as compared with Doric buildings. ”

“ In this case the upright shafts at the sides are not twisted as in the other doors; they are square in plan,156 interrupted by a moulding at the level of the capitals, below which they are carved on each face with large square flowers, while above they have a round moulding at the angles. At the top are plain Gothic pinnacles; behind which rises the enclosing arch, due doubtless to the restoration after the earthquake. The gable-shaped moulding runs from the base of these pinnacles to the top of the ogee, and forms the boundary between the stonework and the plaster. ”

“ A plain semicylindrical moulding, with a square-edged fillet on the face, is also common, and occurs at the church of Orton-on-the-Hill, Leicestershire. The hood moulding over the [113] windows often consists of a quarter-round or ogee, with a cavetto beneath, and sometimes returns horizontally along the walls as a string-course; a disposition, however, more frequently observable in the Early English style than in this: of such disposition the churches of Harvington, Worcestershire, and of Sedgeberrow, Gloucestershire, may be cited as affording examples. ”

“ Q. In what respect do the mouldings of this style differ from those of earlier styles?
A. In a greater prevalence of angular forms, which may be observed in noticing the section of a series of mouldings, and in the bases and capitals of cylindrical shafts. A large and bold but shallow hollow moulding or cavetto, in which, when forming part of a horizontal fascia or cornice, flowers, leaves, and other sculptured details are often inserted at intervals, is a common feature; and such moulding, without any inser [137] tion, is frequent in doorway and window jambs. ”

“ Our fourteenth and fifteenth century buildings present nothing in its place but combinations of mouldings, in themselves very beautiful, but by no means so beautiful as to reconcile us to the loss of that which they so entirely supplanted. One consequence of their introduction, to the exclusion of the detached shaft, was, that the art of sculpture deteriorated just in proportion as the art of moulding was developed. ”

“ Setting up the mould with plaster of Paris.
When the model has been completed, the next thing to be done is to make a mould on it. For this purpose the moulders are called in. Some sculptors do their own moulding; but if they are busy men it does not pay them to do so, the moulding of a large group being a long job. It is, moreover, a strictly mechanical operation, although one requiring much manipulative skill and a fine touch. The first thing the moulder does, when the model is handed over to him, is carefully to consider the way in which he is going to accomplish his task. ”

“ So far of aging; next of effects of light and color. It is, I believe, hardly enough observed among architects that the same decorations are of totally different effect according to their position and the time of day. A moulding which is of value on a building facing south, where it takes deep shadows from steep sun, may be utterly ineffective if placed west or east; and a moulding which is chaste and intelligible in shade on a north side, may be grotesque, vulgar, or confused when it takes black shadows on the south. ”

“ Singularly pleasant to the eye, also, and giving a sense of stability to this fine building, is the noble base-line of strong moulding that follows every length, angle, and recess, and adds the finish of completeness from spire to basement. ”

“ The black joints, too, in which we set our brickwork, grinding cinders into our mortar where the south uses sand, would seem to be what they are, so many dirty lines drawn across the fair faces of our buildings, and thereby adding most unnecessarily to the gloom. A vulgar moulding too, an over-emphasized piece of ornament, would become so conspicuous in proper daylight, when all the surroundings would be clean, that the author of it would begin to be cut by his fellow-architects, and even his lay friends as a man of bad and flamboyant taste. ”

“ In fact the chancel windows of Shiffnal, which are of a somewhat early Decorated, have a moulding of much the same character. Its effect, as regards light and shade, is excellent, and it is probably more durable than a moulding comprising the large hollow so common in the Perpendicular style. This kind of moulding appears in the tower-arches, the pier-arches on the northern side, all the doors, and some of the windows of the north aisle ”

“ A single moulding in the marble cornice above is touched with gold, as an introduction to the rich coloring and profuse use of gilding in the coved ceiling which it supports. The cove itself is of stucco, and is painted blue—the color of the sky, which it is intended to suggest—with yellow penetrations. These penetrations are outlined by a heavy gilt moulding, and give space for ten semicircular latticed windows opening into the rooms of the attic story. ”

“ Great skill and discrimination are required in designing and applying mouldings, but that matter falls to the qualified designer and is perhaps outside the province of the practical workman, whose work is to carry out in an accurate and finished manner the ideas of the draughtsman. The character of a moulding is greatly affected by the nature and appearance of the wood in which it is worked. ”

“ A stuck moulding is worked directly on to the framing it is used to ornament; a planted moulding is separately worked and fixed in position with nails or screws. Beads and other small mouldings should always be stuck; larger ones are usually planted on. In the case of mouldings planted on panelled work, the nails should be driven through the moulding into the style or rail of the framing, and on no account into the panel. ”

“ A particular species of moulding is thus made, which resembles, in its section, that part of the frame of a window which separates two adjacent panes of glass. Being much stronger than wood, it can be considerably reduced in thickness, and consequently offers less obstruction to the light ”

“ Plain, or unenriched, mouldings are formed with a running mould of zinc cut to the required profile. Enrichments may be Mouldings. added after the main outline moulding is set, and are cast in moulds made of gelatine or plaster of paris. For a cornice moulding two running rules are usual, one on the wall, the other on the ceiling, upon which the mould is worked to and fro by one workman, while another man roughly lays on the plaster to the shape of the moulding. ”

“ One of the most distinguishing characteristics of the architectural styles are the mouldings, so much so, that a building having no mouldings is almost, if not entirely, devoid of architectural expression; it may be classed as a structure, but hardly as true architecture, for the style, and even the date of a building may be often determined by the design of its mouldings alone. ”

“ A bold double-billeted moulding is continued below the clerestory, whose windows adapt themselves to the binary arrangement of the bays of the nave; that is to say, a taller arch is flanked by a smaller one, on its right side, or on its left side, as the situation requires; these are supported by short massy pillars; and an embattled moulding runs round the windows. ”

“ The material used is a combination of the clay taken from the hillside with the mud of the low land, and while neither separately would be well adapted to the purpose, this mixture makes an excellent mortar for moulding and burning. There is not a large quantity of brick or tile on hand, but some of all the varieties of style and size, showing the capacity of the establishment to meet any demand. ”

“ Label Moulding, a projecting course of stone running round an arch. When not very large it is sometimes cut on the voussoirs, but is usually made a separate course of stone. Often, and especially in the case of door openings, a small sinking is worked on the top surface of the moulding to form a gutter which leads to the sides any water that trickles down the face of the wall. ”

“ It has been suggested likewise that the distorted heads, which alternate with squares of foliage in the wider inside moulding of the doorway typify the sufferings of the soul in its passage. The outside moulding is also interesting, being a wide hollow in the bottom of which circular holes are cut at intervals. Through these can be seen the broad stem from which spring the leaves that ornament the intervening spaces. The arch head is ogee-shaped outside, with large external, and smaller, but not less rich, internal crockets. ”
