Quarries, as all such little square or rhomboid shaped panes of glass came to be called, were used from the first. Ordinarily they were set on end, so as to form diamonds; which as time went on, were generally not rectangular, but long in proportion to their breadth.

For the most part they were painted with patterns traced in brown; and, on the discovery of silver stain, they were in parts tinted yellow. From the fourteenth century onwards, quarry lights, framed in borders, and enlivened with colour, form a very important variety of grisaille.
Many a grisaille pattern was not far removed from quarry glazing, as may be seen [opposite]. It was natural that, for clerestory and triforium windows in particular, the glazier should do all he could to simplify his work. Clerestory windows are placed too high to be fairly seen in a narrow church, and triforium lights are often half shut off from view by projecting shafts of open arcading in front of them. It is only when, by rare chance, they happen to front you squarely at the end of an aisle or transept, that they are properly seen. There is no occasion, therefore, to indulge in subtleties of design; the one thing needful is that the effect of the windows as a whole, should be pleasant, since all study of detail is out of the question, except from the triforium galleries opposite, or by the aid of a field-glass; and light arrangements of grisaille and colour are in most cases all that is wanted. The colour may be more or less, according as it is desired to exclude light or to admit it; but some very simple, unpretending, and perhaps even rude treatment, is indicated by the conditions of the case, which to contradict, is wasteful and unworkmanlike. The effect, for example, of the band of figures across the grisaille in the triforium of the transepts at Evreux is admirable; but the way in which seven saints out of the eight are cut vertically in two by the pillars of the architectural screen in front of them, is nothing less than exasperating. These figures tell only as the patches of colour; and that could so easily have been obtained by much simpler means. In such a position, quarries may well take the place, not only of figures, but of more interesting grisaille; and, even though they be not painted at all (as is again the case at Evreux), but merely broken by occasional sun-discs in white and stain crossing them, and framed in a simple block border of white and colour, the effect may be entirely adequate. It is not meant to deny that figures in rich colour embedded in carefully designed grisaille are more attractive; but, for its purpose, quarry work, with borders and bosses of colour, is in the majority of such cases, enough.
