First, take a piece of Brasse, or Copper, of what bignesse you intend, of an indifferent thicknesse, and see as neere as you can, that it bee free from fire flawes. First beat it as smooth as you can with a hammer, then rub it smooth with a pumice stone that is void of gravell, (least it race it, & so cause you as much more labour to get them out) burnish it after with a burnishing iron, having first dropped a drop or two of sallet oyle on it: then rub it over with a cole, prepared as is after taught, and lastly with a peece of beaver hat dipt in sallet oyle, rub it very well for an houre: thus you may polish it exactly. _How to prepare your Coales._ Take Beechen charcole, such as when they are broke, doe shine, such as are void of clifts, and such as breake off even: burne them againe, and as soone as they are all through on fire, quench them in chamber lye: after take them out, and put them in faire water, and reserue them for your use. Having prepared all things in a readinesse, you must haue a draught of that you intend to cut or engrave. Take the plate then, and waxe it lightly ouer, and then either pounce the picture upon it, or trace it, or by drawing ouer the lines of the picture with ungummed inke, reprint it upon the Plate: then worke upon it, obseruing the shadow, so that being printed, it may stand right, for it will be backward upon your plate: when you haue cut one stroke, drop a little sallet oyle upon your peece of Bever, and rub over the said stroke, for by this meanes you shall better see the stroke, and how to cut the next equall unto it, and so the rest proportionally distant one from another; but to worke by a Candle, you must place a glasse of faire water betweene the Candle, and a paper betweene that and the Plate, (which casteth a true light) or you will never be able to worke truely and aright. _Of Etching._ Etching is an imitation of engrauing, but more speedily performed. Things may be expressed to the life thereby, but not so sweetly as by the Graver. It is thus performed: the Plate you are to etch upon, must first exactly be pollished, afterwards ouerlaid but very lightly with a ground made for the purpose, (of which anon) and thereupon must be pounced, drawne, or traced, the thing that you are to etch: then the said ground is to be pierced with diuers stiles of seuerall bignesse according as the shadowes of the picture doe require: afterwards the edges of the Plate are to be raised with soft waxe and strong water, (for so they terme it:) (It is to be had at the signe of the Legge in _Foster Lane_ a Distiller) is to be put upon it, which in those places were the strokes, are required to be lightly performed, is to be abated or alayed with faire water, which hauing dured a while upon the plate, will eate into it, as it were engraven, then put it into cold water, and wash it about, and it will leaue eating further, and then take off the ground and it is done.
