If a person gives an article to a craftsman to fix and the craftsman ruins it, the craftsman is liable to make restitution. What is implied? If a person gives a carpenter a chest, a box or a closet to place a nail into, and he breaks the article he must make restitution. Similarly, if a person gives a carpenter the wood to make a chest, a box or a closet, and he breaks them after he completes making them, the carpenter must pay the employer for a chest, a box or a closet. The rationale is that the craftsman does not acquire a share in the increase in the value of the article. If a person gives a craftsman wool to dye, and the vat in which he dyes it boils until the water evaporates, thus destroying the wool, the dyer must reimburse the owner for his wool. The following rules apply in the ensuing situations: The dyer dyed the wool unattractively, the owner asked him to dye it red and he dyed it black, he asked him to dye it black and he dyed it red, or he gave wood to a carpenter to make an attractive chair, and he made a poor chair or a bench. In all these instances, if the increase in the value of the article exceeds the cost, all the owner of the article is required to pay is the cost. If the cost exceeds the increase in the value of the article, all the owner of the article is required to pay is the increase in the value of the article. If the owner of the article says: "I do not desire this dispensation. I would prefer that he give me the value of the wool or the value of the wood," we do not heed his request. Conversely, if the craftsman says: "Here is the cost of your wool or your wood, depart," he is not heeded. The rationale is that the craftsman does not acquire a share in the increase in the value of the article.
