A Brief History of Decals
by Jon Simmons
The progress of the invention of the decal
is comparable to the progress of the invention of the wheel. When we compare
today's steel-belted radials to yesterday's wooden ox-cart wheels, they hardly
seem to have anything in common. So it was when decals first come on the scene.
About 1750, a Frenchman named Simon François
Ravenet perfected a way of engraving on copper plates so that under-glaze
colors could be rubbed onto the heated plates, then tissue paper would be
pressed onto the color, which would adhere to the tissue paper, which was then
removed and transferred to the awaiting bisque or greenware to be decorated. Typically,
the bisque or greenware was coated with a tacky varnish, which would hold the
color while the tissue paper was removed, after which the piece was fired.
Now if that seems like a lot of work, you're
right! But in the good old days, that was the only way you could mass-produce
ceramic ware with pictures on it. By way of example, two guys from Liverpool,
England, John Sadlier and Guy Green, signed an affidavit on July 27, 1756,
certifying that they had hand-decorated 1200 tiles in one 6 hour day for Josiah
Wedgwood (ring a bell?). And that's a lot of tile! It figures out to about 200
tiles per hour, or 3 tiles per minute.
Now Wedgwood had to send those tile to
Sadlier & Green's factory by pack horse because decorating with decals was
a new technology and was kept a closely guarded secret. (That is, until someone
who was working for you learned how it was done and then went out and started
their own factory.) So it was, in the beginning, decorating with ceramic decals
was a highly technical process, that only the initiated few could render.
In the 1750's and 1760's, Robert Hancock
used Ravenet's engraving techniques to produce the best designs of that era.
His apprentice, Thomas Turner, opened the Caughley Pottery Works around 1775, and
in 1779 introduced the most famous and best selling decal of all-time, the
"Willow Pattern", or, "Blue Willow", as we call it today.
Note: It was Turner’s apprentice, Thomas Minton, who perfected the
In the early 1800's, rubber glue bats
(something like "glue pancakes") replaced the tissue paper. The glue
bats were reusable, plus they conformed better to the curved surfaces. In fact,
we'd be using glue bats today had it not been for the Pratt Brothers.
Multiple color printing was a big deal,
because heretofore the only kind of decals that were made were one color,
mono-tone designs. Well, the Pratt Brothers used multiple copper plates to
achieve this. But very soon the lithograph process would take over.
The lithograph process, back then, used
gigantic lime-stone slabs for "printing plates". These were usually
about 2' by 3' and 6 inches thick, weighing hundreds of pounds. These were
polished flat on one side, and the design was etched in the stone, whereupon
they were inserted in enormous flatbed presses. Using these plates, a tacky
varnish was printed onto the tissue paper, which was then dusted with dry
color, and the residue wiped away with lamb's wool. (Kind of like the way they
make litho decals today.)
These decals were applied more or less in
the same way as they always had been, namely, the tissue paper with the design
on it was pressed onto bisque or glazedware that had been coated with a tacky
glue. Then the piece was wetted with water, which released the tissue paper,
leaving the color on the ceramic ware, which was then fired.
Things were going along pretty good until
disaster struck. It happened about 1876. It had a name. It was "Popular
Demand". Somehow, somewhere, someone started decorating with decals as a
hobby. Maybe it was because decals had become much easier to use. Maybe it was
because the lithograph process could turn out such high quality. Maybe it was
because the emerging consumer class couldn't afford hand-decorated china, but
they sure could afford to decorate their own. Nobody knows. But we do know
this: in 1875, there were only about 300 designs available to decorate with; 2
years later, there were 10,000 !!!
It is from this period that the word
"Decalcomania" was coined (meaning "decal craze" or
"love of decals"). And even today, Decalcomania is still a common
word for decals in many countries. (The singular is "decalcomanie".)
But the actual word "Decal" is short for the French word "Decalquer"
(pronounced "De-Kalk "), which means to "copy by tracing".
Remember our friend, monsieur Ravenet?
Other names for decals have been
"mineral transfers" in the United States; "diaphanies" and
"cockamanies" in England (and, yes, that's where we get the word
"cockamamie" from); and "lithographs" and
"lithoplanies" in Europe.
Anyway, in 1895, the next big deal
happened... Duplex Paper. Duplex Paper would reduce the cost of making decals
by 80%! It seems that all this time when decals were being printed onto tissue
paper, the tissue paper had to lightly stuck onto ZINC PLATES before you could
run it through the press. Not exactly quick and easy. Well, the Brittan’s Paper
Company had a better idea. In 1895 they introduced a two part, or
"duplex", paper.
P.S. The Brittans Paper Company is currently
the largest manufacturer of decal paper in the world.
As you can see, ceramic decals are largely a
European ospring. The first decals were probably not imported into the
The last big deal to impact decals was the
advent of silk-screen printing. Commercially developed in the 1930's(?),
silk-screen printing would first make it mark not in the printing of
color, but in the ability to lay down a cover-coat or top-coat of lacquer on
top of the printed design. This would then be used as the transfer medium of
the color, instead of the tissue paper. In 1936, the first firable decal was
printed using a top-coat. It was a glass decal. But it proved to be so easy to
use that within 3 years all glass decals had top-coats.
Decals with top-coats or cover-coats came to
be known as "water-mount decals" because you had to put them in water
before you could mount them. Interestingly, while the glass industry quickly
embraced water-mount decals, the ceramic industry was much slower on the
uptake. It wasn't until the early 1960's that water-mount decals came to
dominate. This was partly because the potteries were comfortable with the old
"varnish mounts" as they called them. Plus, you got more decals for
the money with varnish mounts (because the designs could be packed more tightly
together). Plus, They were cheaper because the step of printing a top-coat was
not needed. Plus, they lasted longer. (Varnish mounts never go bad.)
Since the 60's, printing technology has
advanced at an amazing rate. Computerized scanners and image editors, desktop
publishing and the internet, and an ever improving silk screen industry, have
combined to make ceramic decals so easy to use and in so much variety, that to
compare them with the first decals produced in 1750 is like comparing
steel-belted radials to wooden ox-cart wheels. The only thing they have in
common is that they're pretty.
