There is a common opinion that the ancient art of glass-painting is completely lost. This, however, is so far from being true, that it is now carried to a much higher degree of perfection than ever before, except in one particular color, and even that is very nearly approached to. We can blend the colors, and produce the effects of light and shadow, which the ancients could not do, by harmonizing and mixing the colors in such a manner, and fixing by properly enameling and burning them, that they shall afterwards become just as permanent as those of the ancients, with the additional advantage of superior art. In modern times, glass-painting has been carried to the greatest perfection at Zurich. The process is effected chiefly by colors derived from metals. The colors are laid on by fluxes, as soft glass and easily vitrified bodies. The colors ara affixed by annealing the metals to the glass.
