James Burnley, Dictionary of National Biography… (1890)
“ Ged made many experiments as to the best kind of metal, and at length decided on using a similar alloy to that employed in the manufacture of type. Clay and even copper were subsequently used by other experimenters. Ged succeeded in obtaining a fair cast of a page, thus producing a stereotype; but no Edinburgh printers would enter into the matter with him, and his endeavours to apply his invention were bitterly opposed by the compositors. Ged had to make his experiments in secret, assisted by subscriptions from friends and with the aid of his son James, who had been apprenticed to a printer. ”
