Papier mâché became an industry in England in 1772 when Henry Clay of Birmingham took out a patent for its making and as a result produced the inexpensive plastic of its time, easily be molded into desired shapes. As indicated by its name, it was mashed or pulped paper, which was first, molded, then baked, to drive off the moisture that had reduced it to pulp. When it became firm and hard it was finished with an enamel-like coat of paint and was then ready for a wide variety of decorative treatment.
