The enormous importance of ceramics in its relation to architecture thus becomes apparent. They minister to an architectural need instead of gratifying an architectural whim. Ours is a period of Incrusted architecture—one which demands the encasement, rather than the exposure of structure, and therefore logically admits of the enrichment of surfaces by means of "veneers" of materials more precious and beautiful than those employed in the structure, which becomes, as it were, the canvas of the picture, and not the picture itself. For these purposes there are no materials more apt, more adaptable, more enduring, richer in potentialities of beauty than the products of ceramic art. They are easily and inexpensively produced of any desired shape, color, texture; their hard, dense surface resists the action of the elements, is not easily soiled, and is readily cleaned; being fashioned by fire they are fire resistant.

So much then for the practical demands, in modern architecture, met by the products of ceramic art. The æsthetic demand is not less admirably met—or rather might be.

When, in the sixteenth century, the Renaissance spread from south to north, color was practically eliminated from architecture. The Egyptians had had it, hot and bright as the sun on the desert; we know that the Greeks made their Parian marble glow in rainbow tints; Moorish architecture was nothing if not colorful, and the Venice Ruskin loved was fairly iridescent—a thing of fire-opal and pearl. In Italian Renaissance architecture up to its latest phase, the color element was always present; but it was snuffed out under the leaden colored northern skies. Paris is grey, London is brown, New York is white, and Chicago the color of cinders. We have only to compare them to yellow Rome, red Siena, and pearl-tinted Venice, to realize how much we have lost in the elimination of color from architecture. We are coming to realize it. Color played an important part in the Pan-American Exposition, and again in the San Francisco Exposition, where, wedded to light, it became the dominant note of the whole architectural concert. Now these great expositions in which the architects and artists are given a free hand, are in the nature of preliminary studies in which these functionaries sketch in transitory form the things they desire to do in more permanent form. They are forecasts of the future, a future which in certain quarters is already beginning to realize itself. It is therefore probable that architectural art will become increasingly colorful.

The author remembers the day and the hour when this became his personal conviction—his personal desire. It happened years ago in the Albright Gallery in Buffalo—a building then newly completed, of a severely classic type. In the central hall was a single doorway, whose white marble architrave had been stained with different colored pigments by Francis Bacon; after the manner of the Greeks. The effect was so charming, and made the rest of the place seem by contrast so cold and dun, that the author came then and there to the conclusion that architecture without polychromy was architecture incomplete. Mr. Bacon spent three years in Asia Minor, and elsewhere, studying the remains of Greek architecture, and he found and brought home a fragment of an antefix from the temple of Assos, in which the applied color was still pure and strong. The Greeks were a joyous people. When joy comes back into life, color will come back into architecture.

Ceramic products are ideal as a means to this end. The Greeks themselves recognized their value for they used them widely and wisely: it has been discovered that they even attached bands of colored terra-cotta to the marble mouldings of their temples. How different must have been such a temple's real appearance from that imagined by the Classical Revivalists, whose tradition of the inviolable cold Parian purity of Greek architecture has persisted, even against archæological evidence to the contrary, up to the present day.

In one way we have an advantage over the Greek, if we only had the wit to profit by it. His palette, like his musical scale, was more limited than ours. Nearly the whole gamut of the spectrum is now available to the architect who wishes to employ ceramics. The colors do not change or fade, and possess a beautiful quality. Our craftsmen and manufacturers of face-brick, terra-cotta, and colored tile, after much costly experimentation, have succeeded in producing ceramics of a high order of excellence and intrinsic beauty; they can do practically anything demanded of them; but from that quarter where they should reap the greatest commercial advantage—the field of architecture—there is all too little demand. The architect who should lead, teach and dictate in this field, is often through ignorance obliged to learn and follow instead. This has led to an ignominious situation—ignominious, that is, to the architect. He has come to require of the manufacturer—when he requires anything at all—assistance in the very matter in which he should assist: the determination of color design. It is no wonder that the results are often bad, and therefore discouraging. The manufacturers of ceramics welcome co-operation and assistance on the part of the architect with an eagerness which is almost pathetic, on those rare occasions when assistance is offered.

But the architect is not really to blame: the reason for his failure lies deep in his general predicament of having to know a little of everything, and do a great deal more than he can possibly do well. To cope with this, if his practice warrants the expenditure, he surrounds himself with specialists in various fields, and assigns various departments of his work to them. He cannot be expected to have on his staff a specialist in ceramics, nor can he, with all his manifold activities, be expected to become such a specialist himself. As a result, he is usually content to let color problems alone, for they are just another complication of his already too complicated life; or he refers them to some one whom he thinks ought to know—a manufacturer's designer—and approves almost anything submitted. Of course the ideal architect would have time for every problem, and solve it supremely well; but the real architect is all too human: there are depressions on his cranium where bumps ought to be; moreover, he wants a little time left to energize in other directions than in the practice of his craft. One of the functions of architecture is to reveal the inherent qualities and beauties of different materials, by their appropriate use and tasteful display. An onyx staircase on the one hand, and a portland cement high altar on the other, alike violate this function of architecture; they transgress that beautiful necessity which decrees that precious materials should serve precious uses and common materials should serve utilitarian ends. Now color is a precious thing, and its highest beauties can be brought out only by contrast with broad neutral tinted spaces. The interior walls of a mediaeval cathedral never competed with its windows, and by the same token, a riot of polychromy all over the side of a building is not as effective, even from a chromatic point of view, as though it were confined, say, to an entrance and a frieze. Gilbert's witty phrase is applicable here:

"Where everybody's somebody, nobody's anybody."

Let us build our walls, then, of stone, or brick, or stucco,—for their flat surfaces and neutral tints conduce to that repose so essential to good architectural effect: but let us not rest content with this, but grant to the eye the delight and contentment which it craves, by color and pattern placed at those points to which it is desirable to attract attention, for they serve the same æsthetic purpose as a tiara on the brow of beauty, or a ring on a delicate white hand. But just as jewelry is best when it is most individual, so the ornament of a building should be in keeping with its general character and complexion. A color scheme should not be chosen at random, but dictated by the prevailing tone and texture of the wall surfaces, with which it should harmonize as inevitably as the blossom of a bush with its prevailing tone of stems and foliage. In a building this prevailing tone will inevitably be either cold or warm, and the color scheme just as inevitably should be either cold or warm; that is, there should be a preponderance of cold colors over warm, or vice versa. Otherwise the eye will suffer just that order of uneasiness which comes from the contemplation of two equal masses, whereas it experiences satisfaction in proportionate unequals.

Nothing will take the place of an instinctive colour-sense, but even that needs the training of experience, if the field be new, and a few general principles of all but universal application will not be amiss.
