In order that he might complete the invention, which he now believed to be at hand, he resolved to build for himself a glass-furnace near his dwelling, where he might carry on his operations in secret. He proceeded to build the furnace with his own hands, carrying the bricks from the brick-field upon his back. He was bricklayer, labourer, and all. From seven to eight more months passed. At last the furnace was built and ready for use. Palissy had in the mean time fashioned a number of vessels of clay in readiness for the laying on of the enamel. After being subjected to a preliminary process of baking, they were covered with the enamel compound, and again placed in the furnace for the grand crucial experiment. Although his means were nearly exhausted, Palissy had been for some time accumulating a great store of fuel for the final effort; and he thought it was enough. At last the fire was lit, and the operation proceeded. All day he sat by the furnace, feeding it with fuel. He sat there watching and feeding all through the long night. But the enamel did not melt. The sun rose upon his labours. His wife brought him a portion of the scanty morning meal, - for he would not stir from the furnace, into which he continued from time to time to heave more fuel. The second day passed, and still the enamel did not melt. The sun set, and another night passed. The pale, haggard, unshorn, baffled yet not beaten Palissy sat by his furnace eagerly looking for the melting of the enamel. A third day and night passed - a fourth, a fifth, and even a sixth, - yes, for six long days and nights did the unconquerable Palissy watch and toil, fighting against hope;and still the enamel would not melt.

It then occurred to him that there might be some defect in the materials for the enamel - perhaps something wanting in the flux;so he set to work to pound and compound fresh materials for a new experiment. Thus two or three more weeks passed. But how to buy more pots? - for those which he had made with his own hands for the purposes of the first experiment were by long baking irretrievably spoilt for the purposes of a second. His money was now all spent;but he could borrow. His character was still good, though his wife and the neighbours thought him foolishly wasting his means in futile experiments. Nevertheless he succeeded. He borrowed sufficient from a friend to enable him to buy more fuel and more pots, and he was again ready for a further experiment. The pots were covered with the new compound, placed in the furnace, and the fire was again lit.

It was the last and most desperate experiment of the whole. The fire blazed up; the heat became intense; but still the enamel did not melt. The fuel began to run short! How to keep up the fire?

There were the garden palings: these would burn. They must be sacrificed rather than that the great experiment should fail. The garden palings were pulled up and cast into the furnace. They were burnt in vain! The enamel had not yet melted. Ten minutes more heat might do it. Fuel must be had at whatever cost. There remained the household furniture and shelving. A crashing noise was heard in the house; and amidst the screams of his wife and children, who now feared Palissy's reason was giving way, the tables were seized, broken up, and heaved into the furnace. The enamel had not melted yet! There remained the shelving. Another noise of the wrenching of timber was heard within the house; and the shelves were torn down and hurled after the furniture into the fire. Wife and children then rushed from the house, and went frantically through the town, calling out that poor Palissy had gone mad, and was breaking up his very furniture for firewood! For an entire month his shirt had not been off his back, and he was utterly worn out - wasted with toil, anxiety, watching, and want of food. He was in debt, and seemed on the verge of ruin. But he had at length mastered the secret; for the last great burst of heat had melted the enamel. The common brown household jars, when taken out of the furnace after it had become cool, were found covered with a white glaze! For this he could endure reproach, contumely, and scorn, and wait patiently for the opportunity of putting his discovery into practice as better days came round.

Palissy next hired a potter to make some earthen vessels after designs which he furnished; while he himself proceeded to model some medallions in clay for the purpose of enamelling them. But how to maintain himself and his family until the wares were made and ready for sale? Fortunately there remained one man in Saintes who still believed in the integrity, if not in the judgment, of Palissy - an inn-keeper, who agreed to feed and lodge him for six months, while he went on with his manufacture. As for the working potter whom he had hired, Palissy soon found that he could not pay him the stipulated wages. Having already stripped his dwelling, he could but strip himself; and he accordingly parted with some of his clothes to the potter, in part payment of the wages which he owed him.
