Glass Printing.

Scientific American 24, 15.6.1867

De Mothay has prepared an ink for printing on glass by means of rollers similar to those used in calico printing, after which the glass is subjected to heat and the pitcture is vitrified and fixed in the glass, without producing any distortion or imperfection. Many thousands of plain patterns and mosaics of stained glass produced by this process at a very cheap rate, are already in use for the decoration of church and other windows. The colors are mixed with a solvent of a silicate or silico-borate of potash and lead, as usual in painting on glass, and this composition rendered plastic by resin in turpentine, is applied thickly to the rollers and transferred to the glass, after which it is vitrified in the usual manner.
