We began with a foundation inscription, we will conclude with one twenty-six centuries later. This is a large cast plate of lead 3.6 by 2.4 and an inch thick, now preserved in the Guildhall Museum, which was laid in the foundation of old Blackfriars, then Pitt Bridge:-- “On the last day of October in the year 1760 and in the beginning of the most auspicious reign of George III., Sir Thomas Chitty, Knight, Lord Mayor, laid the first stone of this bridge undertaken by the Common Council of London (in the height of an extensive war) for the public accommodation and ornament of the city (Robert Milne being the architect) and that there may remain to posterity a monument of this city’s affection to the man who by the strength of his genius, the steadiness of his mind, and a kind of happy contagion of his probity and spirit, under the divine favour and fortunate auspices of George II., recovered, augmented and secured the British Empire in Asia, Africa, and America, and restored the ancient reputation and influence of his country amongst the nations of Europe. “The Citizens of London have unanimously voted this bridge to be inscribed with the name of William Pitt.” § X. OF THE DECORATION OF LEAD. One of the most usual methods of decorating lead was to gild it; whole domes were gilt in this way. The dome of St. Sophia at Constantinople seems to have been so treated, and the great arc of gold dominating such an Eastern city must have been a most impressive sight. Many of the late domes are partly gilt, as at the Invalides in Paris. The roof of the ancient basilica at Tours is said to have been like “a mountain of gold.” Old recipe books of the last century give instructions for gilding lead. The following are examples:-- “Take two pounds of yellow ochre, half a pound of red lead, and one ounce of varnish, with which grind your ochre, but the red lead grind with oil; temper them both together; lay your ground with this upon the lead, and when it is almost dry, lay your gold; let it be thoroughly dry before you polish it.” For another ground--“Take varnish of linseed oil, red lead, white lead and turpentine; boil in a pipkin and grind together on a stone.” “Or take sheets of tinfoil, and grind them in common gold size; with this wipe your pewter or lead over; lay on your leaf gold and press it with cotton; it is a fine gilding, and has a beautiful lustre.” Dutch metal was also used on a ground of varnish and red lead, as in second recipe; or gilt leaves of tinfoil on white lead ground in linseed oil, this last took a polish “as if it had been gilded in fire.” Dutch metal should be lacquered on the surface. A cheap substitute for gilding could doubtless be made for large surfaces by laying tinfoil lacquered gold colour. Or for statues the surface of the lead might be made bright and lacquered. The external gilding on the Ste. Chapelle in Paris was done in leaf gold on two coats of varnish.
