fetting the end of (he graver obliquely upon the none, whet rt
very flat and Hoping, in the form of a lozenge, with .an exa£t
and even hand, making a (harp point to the edge of it.
If the graver be not very good, and very exactly and carefully
whetted, it will be impoflible to perform the graving with nice-
nefs and curiofity.
5. The gravingcufbion is a roundifh, but fluttifh leather bag
filled with land to lay the plate upon, on which it may be turned
cafilv any way at pleafure.
The plate muft be turned with the left-hand, according as the
ftrokes which you are Engraving turn ; this is to be attained by
practice and diligent care.
6. The burnifher, which is an iron tool, is ufed in rubbing
out feratches, fpecks, or other things, which may caufe faults in
your work on the plate ; and, alfo, if any ftrokes fhall happen
to be cut too deep or grofs, to make them appear lefs and fainter
by rubbing them with it.
Of the making of gravers. I. You muft be provided with
fome crofs-bow fteel, and procure it to be beaten out into fmall
rods, and foftened ; and, this being done, you may, with a
good file, fhape them as you pleafe ; this being done, heat them
red-hot, and immediately dip them into foap, which will render
them very hard.
2. In doing this obferve, that in dipping them into the foap,
if you turn your hand never fo little away, the graver will be
crooked.
3. If the graver prove too hard, lay the end of it upon a red-
hot charcoal, till it begins to grow yellowifh, and afterwards dip
it in tallow, or, as fome fay, in water, and it will toughen it.
4. Then, having fharpened the graver, ftrike the point of it
into a piece of hard box wood, to take off all the roughnefs a-
bout the points, which was caufed by whetting it upon the oil-
ilone.
5. In the laft place, touch the edge of the graver with a file;
if the file cut it, it is too foft, and will not work ; but, if it will
not touch it, it is fit for the work.
If the graver breaks on the point, it is a fign that it is tempered
too hard ; but, will oftentimes, after a little ufe by whetting,
come to be well conditioned.
Ofpotijh'mg the capper-plate. 1. Take a copper-plate about
the fize of your work, that is to be engraven on it, and that is
free from fire flaws.
2. Hammer it very even and fmooth on a fmooth anvil ; then
take a pumice-ftone, free from gravel, left it fcratch it, and
thereby caufe a great deal of labour to get out the feratches, with
a little water.
