Stories of Invention, Told by Inventors and their Friends

by Edward Everett Hale

"The heat had not been strong enough, but I did not know this; I saw only one more useless expense of money. One of the workmen came to me and said, 'You will never make anything out of this; you had better go back to your own business.'"

Palissy shook his head; he had still in his possession some few valuable articles, souvenirs of happier days, which he could sell to renew his experiments. In spite of the reproaches of his wife, he bought more ingredients and more earthenware, and made new combinations.

Failure again! However, he would not be beaten. Some friends lent him a little money; he sat up at night to make new mixtures of different substances, all prepared with such care that he felt sure some of them must be good. Then he carried them again to the potters, whom he urged to the greatest care. They only shrugged their shoulders, and called him "crack brain;" and when the batch was done, they brought the results to Palissy with jeers. Some of the pieces were dirty white; others green, red, or smoked by the fire; but all alike in being dull and worthless.

It was over. Discouragement took possession of Palissy. "I returned home," he says, "full of confusion and sadness. Others might seek the secret of enamels. I must set to work and earn money to pay my debts and get bread for the family."

Most luckily for him at this time, a task was given him by government, for which he was well suited, and which brought him good pay. The king, Francis I., having had, like many another sovereign, some difficulty with his faithful subjects in the matter of imposts, now found it necessary to make a new regulation of taxes; and for this, among other things, an inspection of the salt marshes on the coasts of France was needed, in order to name the right sums for taxation, and a knowledge of arithmetic was required as well. Palissy was appointed; and to the great delight of his family, who thought that his mind would now be forever diverted from the search for enamel, he set forth to explore the islands and the shores of France. He drew admirable outlines of the forms of the salt marshes, and wrote with eloquence upon the sublimity of the sea.

Ease and comfort came back. His task was ended; but debts were paid, and plenty of money remained.

The first thing he saw on returning home, alas! was the cup,—his joy and despair. "How beautiful it is! how brilliant!" he exclaimed; and once more he threw himself into the pursuit of the elusive enamel.

It was easy to see that the so much admired faience of Italy was simply common baked clay, covered with some substance glazed by heat, but so composed as to adhere to the surface after it had cooled. But what substance? He had tried all sorts of materials; why had none of them melted? Palissy at length decided that the fault had been in using the common potter's furnace. Since the materials were to be vitrified by the process, they should be baked like glass. He broke up three dozen pots, pounded up a great quantity of different ingredients, and spread them with a brush on the fragments; then he carried them to the nearest glass-works. He was allowed to superintend the baking himself; he put the specimens in the oven, and passed the night attending the fire. In the morning he took them out. "Oh, joy! Some of the compounds had begun to melt; there was no perfect glaze, only a sign that I was on the right road."

It was, however, still a long and weary one. After two more years, Palissy was still far from the discovery of enamelling, but during this time he was acquiring much knowledge. From a simple workman he had become a learned chemist. He says himself, "The mistakes I made in combining my enamels taught me more than the things which came right of themselves."

There came a time, which he had once more resolved should be the last, when he repaired to the glass-works, accompanied by a man loaded with more than three hundred different patterns on bits of pottery. For four hours Bernard gloomily watched the progress of baking. Suddenly he started in surprise. Did his eyes deceive him? No! it was no illusion. One of the pieces in the furnace was covered with a brilliant glazing, white, polished, excellent. Palissy's joy was immense. "I thought I had become a new creature," he says. "The enamel was found; France enriched by a new discovery."
