He turned and turned the cup in his fingers, admiring the brilliant surface. "Yes," he said at last; "it shall be so, for I choose! I have already studied the subject. I will work still harder, and reach my aim at last."
Exceptional determination of character was needed for such an object. Palissy knew nothing about the component parts of enamels; he had never even seen the process of baking clay, and he had to begin with the very simplest investigations. To study the different kinds of earth and clay, to acquire the arts of moulding and turning, and to gain some knowledge of chemistry, all these were necessary. But he did not flinch, and pursued his idea with indomitable perseverance.
"Moving only by chance," he says, "like a man groping in the dark, I made a collection of all the different substances which seemed at all likely to make enamel, and I pounded them up fine; then I bought earthen pots, broke them into small bits, numbered these pieces, and spread over each of them a different combination of materials. Now I had to have a furnace in which to bake my experiments. I had no idea how furnaces were usually made; so I invented one of my own, and set it up. But I had no idea how much heat was required to melt enamels,--perhaps I heated my furnace too much, perhaps not enough; sometimes my ingredients were all burned up, sometimes they melted not at all; or else some were turned to coal, while others remained undisturbed by the action of the fire."
Meanwhile the resources of the unlucky workman were fast diminishing; for he had abandoned his usual work, by which he earned his living, and kept making new furnaces, "with great expense and trouble, and a great consumption of time and firewood."
This state of affairs much displeased his wife, who complained bitterly, and tried to divert her husband from an occupation which earned for him nothing but disappointment. The cheerful little household changed its aspect; the children were no longer well-dressed, and the shabby furniture and empty cupboards betrayed the decay which was falling upon the family. The father saw with profound grief the wants of his household; but success seemed ever so near to him, that he could not bear to give it up. His hope at that time was but a mirage; and for long afterwards, in this struggle between intelligence and the antagonism of material things, ill fortune kept the upper hand.
