Abstract
December 14, 688.—On Dec. 14, 1688, Abraham Thevart was granted a privilege for 30 years by Louis XIV “de faire seul, à l'exclusion de tous autres, de fabriquer ott bon leur semblera, des glaces de soixante pouces de haut, sur quarante pouces de large, et de toutes autres hauteurs et largeurs au-dessus, … et pour cet effet se servir seulement des machines que ledit Thevart a inventées ”, on condition that a description of the process be presented within three months. Thevart set up his factory first in the Faubourg St. Antoine and later at St. Gobain, where large sheets of glass were cast in 1 693, the first four pieces being presented to the king. In England the first large glass sheets were manufactured by the Company of British Cast Plate Manufacturers, formed in 1773, in a factory at St. Helens, Lancashire.
