In the first place—seeing that the trade of pewtery is founded upon certain matters and metals, such as copper, tin, and lead, in due proportions; of which three metals they make vessels, that is to say, pots, salt-cellars, _esquelles_,[15] _platers_, and other things by good folks bespoken; which works demand certain mixtures and certain alloys, according to the manner of vessel so bespoken; the which things cannot be made without good knowledge of a pewterer, well taught and well informed in the trade; seeing that many persons, not knowing the right alloys, nor yet the mixtures or the right rules of the trade, do work and make vessels and other things not in due manner, to the damage of the people, and to the scandal of the trade; the good folks of the trade do pray therefore that it may be ordained that three or four of the most lawful and most skilful in the trade may be chosen to oversee the alloys and the workmanship aforesaid; and that by their examination and assay, amendment may speedily be made where default has been committed. And that if any one shall be found rebellious against the Wardens and Assayers, the default may be shown, with the name of the rebellious offender, unto the Mayor and Aldermen; and that by them he may be adjudged upon, in presence of the good folks of the trade, who have found such default. And be it understood, that all manner of vessels of pewter, such as _esquelles_, salt-cellars, platters, chargers, _pichers_ squared, and _cruetz_ squared, and chrismatories, and other things that are made square or ribbed, shall be made of fine pewter, with the proportion of copper to the tin as much as, of its own nature, it will take. And all other things that are wrought by the trade, such as pots rounded, _cruetz_ rounded, and candlesticks and other rounded vessels that belong to the trade, ought to be wrought of tin alloyed with lead in reasonable proportions. And the proportions of alloy are, to one hundred weight of tin 22 pounds of lead; and these are always called ‘vessels of pewter.’ Also, that no person shall intermeddle with the trade aforesaid, if he be not sworn before the good folks of the trade lawfully to work according to the points ordained; such as one who has been an apprentice, or otherwise a lawful workman known and tried among them. And that no one shall receive an apprentice against the usage of the City. And those who shall be admitted therein, are to be enrolled, according to the usage of the City.
