It was a very profitable job, and Palissy's affairs began to look more flourishing. But the work was no sooner concluded, than the "will o' the wisp," as his wife and neighbours held it, was dancing again before his eyes, and he was back, with redoubled energy, to his favourite occupation, "diving into the secret of enamels." Two years of unremitting, anxious toil, of grinding and mixing, of innumerable visits to the kiln, sanguine of success, with ever new preparations; of invariable journeys home again, sad and weary, for the moment utterly discouraged; of domestic bickerings; of mockery and censure among neighbours, and still the enamel was a mystery,--still Palissy, seemingly as far from the end as ever, was eager to prosecute the search. He appeared to have an inward conviction that he would succeed; but meanwhile the remonstrances of his wife, the pale, thin faces of his bairns, warned him he must desist, and resume the employments that at least brought food and clothing. There should be one more trial on a grand scale,--if that failed, then there should be an end of his experiments. "God willed," he says, "that when I had begun to lose my courage, and was gone for the last time to a glass-furnace, having a man with me carrying more than three hundred pieces, there was one among those pieces which was melted within four hours after it had been placed in the furnace, which trial turned out white and polished, in a way that caused me such joy as made me think I was become a new creature." He rushed home, burst into his wife's chamber, shouting, "I have found it!" From that moment he was more enthusiastic than ever in his search. He had discovered the white enamel. The next thing to be done was to apply it. He must now work at home and in secret. He set about moulding vessels of clay after designs of his own, and baked them in a furnace which he had built in imitation of the one at the pottery. The grinding and compounding of the ingredients of the enamel cost him the labour, day and night, of another month. Then all was ready for the final process. The vessels, coated with the precious mixture, are ranged in the furnace, the fire is lit and blazes fiercely. To stint the supply of fuel would be to cheat himself of a fortune for the sake of a few pence, so he does not spare wood. All that day he diligently feeds the fire, nor lets it slacken through the night. The excitement will not let him sleep even if he would. The prize he has striven for through these weary years, for which he has borne mockery and privation, is now all but within his grasp; in another hour or two he will have possessed it.
