14 Glazing.  13

In all the operations of glazing, the ground that is be glazed, should be made of a drying nature - the glazing should be left so - because, if otherwise, the painting will crack - the last hard coat, by contracting, will tear up the under one.  As a general rule begin to retouch by [[crossed out]] a general [[/crossed out]] glazing over the parts to be repainted.  This moistens and prepares [[crossed out]] the paint [[/crossed out]] them and harmonizes the shadows.  If too dark, the glazing may be lessened by the application of Buckskin to wipe it off.  Then commence painting by forming the shadows & shadowy parts, before touching the middle tints and lights.  This process shows the propriety of beginning a Picture not too dark, as it may thus be darkened by degrees, and be refined by repeated glazings and retouchings.

A new soft bristle brush should be used to glaze on flesh, over backgrounds and other large surfaces a sponge may be used, [[strikeout]] using [[/strikeout]] employing the brush to finish it.  Sometimes the colour will not adhere (resembling water on oil colour)-- In this case rub it with the finger, or breathe upon it.  This effect sometimes occurs in varnishing a Picture and is corrected in the same manner.  It is a good practice before repainting on a Picture that has been  drying some time to wash it well.  To coat it with fine Whiting in water, and, after drying to wash it off effectually remedies a greasy surface.

In glazing [[strikeout]] to enrich it [[/strikeout]] upon Drapery that has been fully painted up, with the lights and shadows of the folds well defined, it is sometimes important to wipe off a  little of the glazing on lights, either with a piece of Buckskin or zag; and then, if it appears necessary, to repeat, with the glazing brush, any little parts near or on the lights.  To rub over the whole with the fingers, if the Canvass is not too rough, often produces an agreable effect, by removing the apparent newness of the work-- a few retouches may be added -- and, if necessary when dry it may be glazed again.  It is sometimes necessary to moisten with drying oil parts that are to be glazed, when the colour may not evenly adhere.  The softening brush may be used to make it more even.  Glazing is generally performed by too quick a motion of the Brush, because the paint, by its texture cannot thus be readily spread, acting only  on the prominent parts of the Canvass.
