"Oh, yes. Almost every European nation has tried its hand at glass-making. It is curious, too, to notice how each differs from the others. The Bohemians, for instance, were famous glass-makers, and their work, which primarily imitated that of the Venetians, is known the world over." "What sort of glass is it? Could I tell it if I should see it?" "Well, for one thing they make beautiful wine glasses and goblets, having stems of enclosed white and colored enamel tubes twisted together with transparent glass, which look as if they had delicate threads of color running through them. Then the Bohemians and the Austrians make many great beakers or drinking glasses, steins, and bowls with decorative coats of arms upon them in gold or in colored enamel." "Oh, I have seen things like that," Jean replied. "Yes, we have some of those ornamental goblets at home in the dining-room. They are very rich and handsome. Beside these varieties the Bohemians have of late revived the making of old white opaque glass with colored enamel figures on it. But engraved glass is one of the kinds for which Bohemia is chiefly celebrated. Even very skilful glass engravers can be had there for little money. They cut fine, delicate designs upon the glass with a lathe. Some of this is white, but much of it is of deep red or blue with the pattern engraved on it in white. Such glass is made in two layers, the outer one being cut away so to leave the design upon the surface underneath." "Wasn't it the Bohemians who invented cut glass?" Giusippe asked. "No. Sometimes people say so, but this is not true. The fact is that there chanced to be a glass cutter so skilful that he was appointed lapidary to Rudolph the Second; he had a workshop at Prague, but though he did some very wonderful glass cutting, which gained him much fame, he did not invent the art. It was, by the way, one of his workmen who later migrated to Nuremburg and carried the secret of glass-cutting to Germany." "Isn't it queer how one country learned of another?" reflected Jean. "Yes, and it is especially interesting when we see how hard each tried not to teach his neighbor anything. There always was somebody, just as there always is now, who could not keep still and went and told," Mr. Cabot said. "And while we are speaking of the different kinds of glass we must not forget to mention the dark red ruby glass perfected in 1680 by Kunckel, the director of the Potsdam glass works, for it is a very ingenious invention. The deep color is obtained by putting a thin layer of gold between the white glass and the coating of red." "What else did the Germans make?" queried Giusippe.
