With some trouble, however, we deciphered the MS., with the exception of six or eight words, of which I took facsimiles. The MS. appears to have been composed in the latter part of the seventeenth or beginning of the eighteenth century. That it was not written previous to 1670 is certain, because Volpato quotes the work of Padre Lana, which was published in that...

Сторінка 483 - Lippi ; and there is an anonymous Bolognese manuscript preserved belonging to the same period, the instructions in which apply precisely to the Wakefield painting.

Сторінка 614 - To obtain a yellow, silver is employed, which, either in the metallic or in any other form, possesses the singular property of imparting a transparent stain, when exposed to a low red heat in contact with glass. This stain is either yellow, orange, or red, according to circumstances. For this purpose no flux is used : the prepared silver is merely ground up with ochre or clay, and applied in a thick layer upon the glass. When removed from the furnace the silver is found not at all adhering to the...
Сторінка 615 - If a large proportion of ochre has been employed, the stain is yellow ; if a small proportion, it is orange-coloured; and by repeated exposure to the fire, without any additional colouring matter, the orange may be converted into red. This conversion of orange into red is, I believe, a matter of much nicety, in which experience only can ensure success. Till within a few years this was the only bright red in use among modern glasspainters; and though the best specimens certainly produce a fine effect,...
