_On the apparent characters of encaustic paintings, on wax and
varnish._
The principal apparent characters of an encaustic painting are,
1. The colours have all the airiness of water colours, and all the
strength of paintings in oil, without partaking of the apparent
character, or defects of either.
2. You may look at and enjoy a picture in any light; the colours are
bright, fresh and lively without glaring. They require no varnish.
3. The colours are firm, without being brittle, and will bear
scratching without receiving any harm.
The effect of the colours is the same in both systems, each will have
and preserve its peculiar character, as to the manner of painting; if
you paint your subject in the light and airy stile of the Carlo Marat
school, when the colours will be fixed you will have the high colouring
of Rubens.
On WAX.
It is not material for me to decide which of the two ought to be
preferably employed, bees-wax simple, or virgin-wax.--For large works
that will be exposed to the air, I should prefer the former; artists
will see by a few trials which will suit their taste best.
On VARNISH.
Varnishes are not required, as has already been observed; but as our
eyes have been used so much to see colours, not in their natural hue,
but disguised by varnish, those that should like to please themselves
in this point may use the following method.
First lay on with a clean spunge a substantial lay of the white of
eggs, and work it well upon the picture. This dry, lay on any varnish
commonly used for oil painting, and your picture will look as if
painted with oil-colours.
This varnish may be taken off at pleasure, the uppermost by rubbing
the surface of the picture with a rag dipped in spirit of wine or
turpentine, the white of eggs by washing the picture with water. It is
not adviseable to lay a varnish of spirits or gums, without first using
the white of eggs, as spirit of turpentine is the menstruum of wax.
