MAKING COLORED GLASS.

WHERE three colors are desired, pots containing each color are made. A blow-pipe is dipped first in one, and then a coating of another is put on, and finally the third layer put on. The glass is then blown into the desired shape. At first the different colors of glass all present the appearance of crystal glass; but, upon being heated, their respective colors are developed. Then a cut is made in the glass of whatever form or shape that may be desired, and extends into the layer of the color that is wanted, and the figure appears in precisely the form and color wished. A small quantity of ruby glass can be so blown as to cover a large piece of crystal glass, and though it is but a mere skin over the surface, yet it will give the whole a perfect color. Then the skim of ruby glass may be cut through, and the fine effect of ruby and crystal in the same piece given. The colored glass in ordinary tableware is nearly all stained, save one or two cheap shades of amber. Manufacturers say that the demand for colored glass is fast dying out, and that pure crystal ware is mostly called for.—Pittsburgh Dispatch.
