Bees-wax is an animal secretion, formed by the bees, and constitutes the material of which the cells of the honey-comb are composed. After the honey is removed, the wax is dirty, tough and yellow. To make it pure and white, the wax is melted and stirred in boiling water; when cooled the pure wax rises to the top. It is again melted, and then bleached in the open air, until it becomes white. It is finally melted, strained through sieves and cast in molds.
