Suggestions as to the proper method of
applying a decalcomania transfer on a lacquered
veneer surface are set forth in an instructive
article in the current issue of Veneers, and
contain a number of points of interest to piano
builders and finishing foremen facing this prob-
lem. The article is written by an individual
signing the initials P. J. M. and follows below.
"With the advent of clear and colored
lacquers," he writes, "decalcomania transfers
are still being used, but many people have ex-
.perienced considerable trouble in applying them
in a satisfactory manner. Some people have
made the mistake of trying to use library paste,
glue, white shellac and similar mediums for
sticking the transfer to the work, with the re-
sult that when a coat of clear lacquer was ap-
plied over the transfer it was softened and
blistered up by the lacquer solvents.
"The proper method of applying a decalo-
mania transfer on lacquered work is first to bring
up the finish in the colored lacquer enamel or
in the clear lacquer to all but the last coat. This
is then sanded or rubbed smooth where extra-
smooth work is wanted, and the back of the
transfer is coated either with the cement which
is furnished by the manufacturer of the decal-
comania transfer or with a good grade of rub-
bing and polishing varnish which has been
thinned down considerably with turpentine.
"The transfer is allowed to stand for a few
moments after the varnish or cement has been
applied so that it begins to take on a slight
