Porcelain Universal Style Chart
All the drawings for the Universal Style Chart are accurate scale drawings
made from either (1) styles listed in the catalogs of all the porcelain
companies from the 1890's to date or, (2) specimens which were never pictured in
catalogs.
Companies cataloged items which were popular styles with a number of
customers and which the company preferred to make and standardize on. Some
styles were made in very large quantities for one or more customers are common
in collections but which were never catalog items.
There are somewhat in excess of 200 different glass CD shapes in the glass
Consolidated Design chart, but we already have over 800 different porcelain U-
shapes in the published porcelain Universal style chart. And the number keeps on
growing. Drawings are already complete for 51 more new ones, and this number
will swell by the time the next style chart supplement is published.
We are still missing a number of the early classics in the porcelain style
chart. In the various catalogs before 1909, the insulators were pictured with
some rather fuzzy art sketches only, and the one pictured here is one of the
better views. With a few exceptions, we have not yet been able to make accurate
drawings of these items for the porcelain style chart and have to hack away at
it by making the drawings from specimens as they turn up in collections. We are
also hampered by the fact that no person that I know of has located pin type
catalogs of Imperial Porcelain Works, Electrical Porcelain & Mfg. Co. and
Peru Electric Mfg. Co. (all these from the 1890-1900 period).
Quite some time ago I started a file of what I have always labeled my
"best can" drawings, and these are made by referring to the fuzzy
pictures and tabulated data in the early Locke, Thomas, New Lexington and Parker
(jobber) catalogs. There were over 50 of these originally, but the number has
been reduced as specimens showed up so we could make accurate drawings and put
them into the U- chart.
The 32 holdouts in this "best can" file are shown on the following
pages (1/4 scale). Please pardon the drawing sharpness, but we reduced these
twice by Xerox and once by Crown Jewels photog. I would like to hear from anyone
who has actual specimens of any of these. A few are somewhat close to items
already in the style chart, so please don't write about new items until you have
checked them closely with those we already have. The catalog source of each one
is shown in the listing below.
One reason for having this file was to make provisions for later assignment
of U- numbers in the proper order, as we are perpetually cramped for numbers in
some places in the chart. Tentative U- numbers are shown for each item, but
permanent numbers are assigned only when items are actually added to the chart -
once each year.
