Below is described how to etch in gold on glass a dull letter with a burnished edge. The glass must first be well cleaned and polished with an old newspaper. A sketch of the letter having been placed on the glass, all those parts of the design that are not to show a dull or matt surface must he carefully covered with asphaltum or embossing black. The glass plate is then surrounded with a raised border composed of wax and Burgundy pitch, and when the protecting asphaltum is dry the plate is flooded with the etching acid. When the glass has been etched to the required depth, the acid is poured off and the plate well washed in cold water and dried and polished. The plate is then sized for gilding, the size being made of a little isinglass boiled in distilled water or filtered rain-water. Apply when cold with a flat camel-hair brush. The gold leaf is then laid on, and when dry is well rubbed with cotton-wool until all the marks are removed. The letter is then backed with red lead ground in quick-drying hard varnish, thinned with benzoline.

When the backing-is dry, wash off the surplus gold.
