The arms of Schools, Colleges and Universities, and of other corporations and institutions, motives that are allusive rather than personal, are yet of the keenest interest to those concerned, an interest that is too often tempered by the unworthiness of the heraldic treatment. The practice of hanging on the wall shields of arms of the stationers’ shop type may be necessary for commercial reasons, but is much to be deplored. It seems impossible to get them improved, the feeling that they are “good enough” (and perhaps they are!) appears to be sufficient recommendation. Even when the arms are well treated, as is rarely the case, and I am not now referring only to the kind which satisfies the aesthetic perception of the casual schoolboy, the effect of the hanging shield in an ordinary room suggests at best a kind of Strawberry Hill Gothic that is out of keeping with any probable surroundings. When heraldry that can be treated as a movable picture is needed, and something of this kind is made necessary by the want of permanence in our dwelling-places, a framed panel of arms is probably the most suitable form that modern heraldic wall decoration can take. It may be in wood or metal, in colour or monochrome, of any quality and interest that may be found most pleasing, and being framed, it will take its place in the adornment of an ordinary room in the same way that a picture does.
Stained Glass.—Of all methods of heraldic expression stained glass is perhaps the most appropriate as purely decorative treatment of the subject, for not only is the splendour of colour peculiarly fitting, but even the commemorative quality of heraldry assimilates in feeling with the memorial character which is rarely absent from a stained window.
The temptation which it naturally offered to partisan fury has left comparatively little of the early work, but sufficient has remained to show how perfectly it could be made to serve its purpose.
In a form of design which is carried out with pieces of coloured glass cut to the necessary shapes and held together by strips of grooved lead, which is soldered into position, this structural lead-work presents considerable difficulty. It follows the lines of the composition wherever possible, but when the shape of the glass makes another course desirable, it does not hesitate to go across a space, and in that case, being frankly used for structural reasons, it must not clash with those lines that help to define form. In short, design in this, perhaps more than in other arts, must conform to the dictation of the material. Thus it is important that the pieces of glass should be designed of cutable shape without too small re-entering angles, and the limits of bending in the lead must also be recognized. Its passing across objects is vindicated by structural necessity, and by that alone, and narrow places are leaded across, not only because of any difficulty that there may be in the cutting, but because the glass would probably break there when being fired in a kiln, or when under the strains that are set up in a window by wind pressure.
The tendency of outline to lose itself in the darker of the colours that it divides has already been referred to, and is very notable in this connexion. When therefore the objects are light on dark, the lead-work will sink into the background, and although it may leave small space for the glass, it is sometimes surprising how efficiently that little lights up and expresses the colour. If the charges are inconveniently small for the leading, resort is had to what is called flash glass, which consists of two layers, of which one only is coloured, and is made by dipping a piece of molten white into a coloured glass, when the mass is about to be blown into the bulb which, shaped and expanded, ultimately becomes a sheet of glass. The desired shapes are pierced through the coloured layer of the composite sheet by means of grinding, or by etching with hydrofluoric acid, and are left white, or stained yellow with a solution of silver, as the case may be.
In addition to the lead-work, which defines the general forms with more or less accuracy, details are depicted by means of a brown enamel colour, which serves also as a general shadow tint, being painted on the glass, and then fired. The brown enamel is also used for the diapering which is so especially valuable in glass decoration, and for this purpose it may express the design in lines drawn with the colour or, being applied as a broad wash; the diaper pattern may be scratched out of it with a point. As a general rule over-painting should be used as sparingly as possible for the purpose of defining or emphasizing form.
The silver stain can be similarly put on, either in lines or in washes, these materials, either alone or in combination, serving to express surface decorations of all degrees of elaboration.
In addition to the accurate and expressive drawing which goes to make good heraldry, the principal feature of glass design is obviously its colour effect, the grouping of the colour masses in such a way as will best express the subject in beautiful coloured light. In view of the obligatory nature of heraldic tinctures, though not of their exact quality, the harmony of colour may be helped by suitable treatment of the background (which is susceptible of variation that is only limited by the nature of the materials) in combination with the prescribed colours of the heraldry. And here occurs that temptation to alter the tinctures of mantlings which has proved too much for the correctness of some heraldic compositions.
The design is usually made on a small scale, showing the colour scheme and the general composition, and a full-size drawing in black and white is then prepared, in which the arrangement of the leading and the character of other details are carefully indicated. On this the various coloured glass is laid and cut into the required shapes, which are then arranged in due order with the lead, and the whole is securely soldered together. The lead having a double groove is in section like the letter H, the inside surfaces being milled, to afford a better key for the glass and for the cement which is added for additional security.
Pugin, whose influence on architecture was so impressive, had no less strong an effect on the heraldry which accompanies it so appropriately, and the beautiful armorial decoration of the Houses of Parliament, for which he is answerable, is a wonderful mass of fine work in glass and stone and other materials. No less remarkable in that it succeeded a long period of such extreme weakness, and was itself but the firstfruits of the revived interest in the subject.
