ON THE RESTORING OF ANCIENT WINDOWS

Let us realise what _is_ done.

And let us consider what _ought to be done_.

A window of ancient glass needs releading. The lead has decayed and the whole is loose and shaky. The ancient glass has worn very thin, pitted almost through like a worn-out thimble with little holes where the alkalis have worked their way out. It is as fragile and tender as an old oil-painting that needs to be taken off a rotten canvas and re-lined. If you examine a piece of old glass whose lead has had time to decay, you will find that the glass itself is often in an equally tender state. The painting would remain for years, probably for centuries yet, if untouched, just as dust, without any attachment at all, will hang on a vertical looking-glass. But if you scrape it, even only with the finger-nail, you will generally find that that is sufficient to bring much--perhaps most--of the painting off, while both sides of the glass are covered with a "patina" of age which is its chief glory in quality and colour, and which, or most of which, a wet handkerchief dipped in a little dust and rubbed smartly will remove.

In short, here is a work of art as beautiful and precious as a picture by Titian or Holbein, and probably, as being the chief glory of some stately cathedral, still more precious, which ought only to be trusted to the gentle hands of a cultivated and scientific artist, connoisseur, and expert. The glass should all be handled as if it were old filigree silver. If the lead is so perished that it is absolutely impossible to avoid taking the glass down, it should be received on the scaffold itself, straight from its place in the stone, between packing-boards lined with sheets of wadding--"cotton-wool"--attached to the boards with size or paste, and with, of course, the "fluffy" side outwards. These boards, section by section, should be finally corded or clamped ready for travelling _before being lowered from the scaffold_; if any pieces of the glass get detached they should be carefully packed in separate boxes, each labelled with a letter corresponding to one placed on the section as packed, so that there may be no chance of their place ever being lost, and when all is done the whole window will be ready to be gently lowered, securely "packed for removal," to the pavement below. The ideal thing now would be to hire a room and do the work on the spot; but if this is impossible on account of expense and the thing has to bear a journey, the sections, packed as above described, should be themselves packed, two or three together, as may be convenient, in an outer packing-case for travelling. It should be insured, for then a representative of the railway must attend to certify the packing, and also extra care will be taken in transit.

Arrived at the shop, the window should be laid out carefully on the bench and each bit re-leaded into its place, the very fragile pieces between two bits of thin sheet-glass.

Unless this last practice is adopted _throughout_, the ordinary process of cementing must be omitted and careful puttying substituted for it. While if it _is_ adopted the whole must be puttied _before_ cementing, otherwise the cement will run in between the various thicknesses of glass. It would be an expensive and tedious and rather thankless process, for the repairer's whole aim would be to hide from the spectator the fact that anything whatever had been done.

What does happen at present is this. A country clergyman, or, in the case of a cathedral, an architectural surveyor, neither of whom know by actual practice anything technically of stained-glass, hand the job over to some one representing a stained-glass establishment. This gentleman has studied stained-glass on paper, and knows as much about cutting or leading technically and by personal practice, as an architect does of masonry, or stone-carving--neither more nor less. That is to say, he has made sketch-books full of water-colour or pencil studies, and endless notes from old examples, and has never cut a bit of glass in his life, or leaded it.

Well, he assumes the responsibility, and the client reposes in the blissful confidence that all is well.

Is all well?

The work is placed in the charge of the manager, and through him it filters down as part of the ordinary, natural course of events into the glazing-shop. Here this precious and fragile work of art we have described is handed over to a number of ordinary working men to treat by the ordinary methods of their trade. They know perfectly well that nobody above them knows as much as they, or, indeed, anything at all of their craft. Division of labour has made them "glaziers," as it has made the gentlemen above stairs, who do the cartoons or the painting, "artists." These last know nothing of glazing, why should glaziers know anything of art? It is perfectly just reasoning; they do their very best, and what they do is this. They take out the old, tender glass, with the colour hardly clinging to it, and they put it into fresh leads, and then they solder up the joints. And, by way of a triumphant wind-up to a good, solid, English, common-sense job, with no art-nonsense or fads about it, they proceed to scrub the whole on both sides with stiff grass-brushes (ordinarily sold at the oil-shops for keeping back-kitchen sinks clean), using with them a composition mainly consisting of exactly the same materials with which a housemaid polishes the fender and fire-irons. That is a plain, simple, unvarnished statement of facts. You may find it difficult of belief, but this is what actually happens. This is what you are having done everywhere, guardians of our ancient buildings. You'll soon have all your old windows "quite as good as new." It's a merry world, isn't it?
