7. _Préler._ This is rubbing with horse’s tail (_shave-grass_) the parts
to be yellowed, in order to make them softer.
8. _Yellowing._ With this view _yellow ochre_ is carefully ground in
water, and mixed with transparent colourless size. The thinner part of
this mixture is applied hot over the white surface with a fine brush,
which gives it a fine yellow hue.
9. _Ungraining_; consists in rubbing the whole work with shave-grass, to
remove any granular appearance.
10. _Coat of assiette; trencher coat._ This is the composition on which
the gold is to be laid. It is composed of Armenian bole, 1 pound;
bloodstone (hematite), 2 ounces; and as much galena; each separately
ground in water. The whole are then mixed together, and ground up with
about a spoonful of olive oil. The _assiette_ well made and applied
gives beauty to the gilding. The _assiette_ is tempered with a white
sheepskin glue, very clear and well strained. This mixture is heated and
applied in three successive coats, with a very fine long-haired brush.
11. _Rubbing_, with a piece of dry, clean linen cloth; except the parts
to be burnished, which are to receive other two coats of _assiette_
tempered with glue.
12. _Gilding._ The surface being damped with cold water, (iced in
summer) has then the gold leaf applied to it. The hollow grounds must
always be gilded before the prominent parts. Water is dexterously
applied by a soft brush, immediately behind the gold leaf, before laying
it down, which makes it lie smoother. Any excess of water is then
removed with a dry brush.
