a different diluent. The addition of one or other transparent pigment
will naturally suggest itself, in
which case it is best to employ
white shellac.
Raw linseed oil, and for a
darker tint, boiled oil, will
answer the purpose of a slight
tinting, as will most of the
varnishes; while at the same
time they harden and protect
the surface. A colouring which
can be partially washed off if
required, can be imparted by
powder colours mixed with
thin size, a preparation which
is practically distemper. It is
sometimes useful thus to be
able to experiment with a cast
before committing it to more
serious and irrecoverable ma-
terials. Many of the plasters,
and, of course, gesso of whiten-
ing, will admit of a large pro-
portion of powder colour being
mixed with them without the
plaster losing its setting quality.
A manufacturing company, ot
12 7 Pomeroy Street, Hatcham,
S.E., prepares a very slow set-
ting plaster already mixed with
colours. This affords many
beautiful colour schemes in
fair tones which are admirably
decorative; it has been
largely used in America. This
material, Gypsomine, Alabas-
tine, Plastico, or whatever
name it is sold under, is un-
doubtedly very handy for low
relief, and in a way saves time,
but it is doubtful whether any-
one who has used the old
gesso, made of whitening glue
and oil, making it himself,
would for general purposes of
designed by m. fernie, Scarborough " boss " modelling prefer Alabastine.
