"You said you had none, if I remember.

How is it that you have it now?
Have you changed one of the crucibles ?" "Yes.

One of the experiments succeeded so well that it seemed better to take out all the glass." "May I see a piece of it ?" inquired Giovanni, as if he were asking a great favour.
It was one thing to let him test the glass himself, it was quite another to show him a piece of it.

He would see it sooner or later, and he could guess nothing of its composition.
"The specimen is there, on the table," Zorzi answered.
Giovanni rose at once and took the piece from the paper on which it lay, and held it up against the light.

He was amazed at the richness of the colour, and gave vent to all sorts of exclamations.
"Did you make this ?" he asked at last.
"It is the result of the master's experiments." "It is marvellous! He has made another fortune." Giovanni replaced the specimen where it had lain, and as he did so, his eye fell on the phial Zorzi had made that morning.
