In my opinion the above sample Of china
clay is of very good quality.

The following is from report OF Prof.
Cox, dated in 1898, on Lake county, Flor
ida kaolin lands. Prof Cox was one of
the committee on porcelain and kaolins
for the Centennial exposition. He says:
THE exposures made by the creek and
the development work that has been done,
leave no doubt regarding the magnitude
and extent of kaolin beds.
The kaoli1 in Lake county, as l stated
above, rests on the nocene limestone, and
is from twenty-five to thirty feet, or more,
in thickness. In places 1t outcrops. but
mostly has an overburden of from one to
two or more feet of ferruginous sand.
"If we estimate the average depth of
the crude kaolin at twenty-four feet and
the percentage of prepared clay ready for
1900 tons to the acre: Each cubic yard
will make full ton. However, 1t Is sim
ply necessary to state that you have
enough first and second-class clay to sup
ply the world for great many years, If
all other mines were closed up 1t Is my
opinion that when fully prepared and
equipped with machinery. you can furnish
ii at less cost than can be done else
where. Respectfully submitted,
Z. r. Cox, M. &c.
Kaolin is usually found in primitive
mountains, amid blocks OF granite, form
ing interposed strata. 1t Is thus the kao-
lin quarries of China and Cornwall, and
shaft mines of Pennsylvania. In Lake
county, Florida, on the other hand the
over-burden is small, and the clay can be
got by open surface mining. No curb.ng
Is even needed to prevent caving. Work
can be carried on continuously throughout
the year, and the material delivered d.
rectly from the mines to the works. A
good supply of water Is at hand, and at
points along the stream water power is
available. These advantages much more
than counterbalance the difference of
freight compared with the clays, inferior
In quality, nearer to existing potteries.
Kaolin forms about 80 per cent. of the
materials of most porcelains, and is the
main Ingredient of other potteries.
Among the uses TO which the Palatua-
kaha kaolns of Lake county, Florida, are
specially adopted are the manufacture of
porce aims, china ware, granate ware, ter
ra Gotta, glazed bicks and tiles fire bricks
filing for paper and cloth, etc. Also OF
fine glass, alum, etc.
The bulletin Of the treasury department
United States America, for June. 1893
April 30, we imported 1871, 764 OF earthen,
stone and china ware, while for the same
period we exported of same but Sl9l 243
Florida kaoln should be a chief factor
towards reversing this.
The quality and character OF clays do
not depend on their composition as shown
by analysis alone. but potter's selecting
clay for their purposes, have to make
practical tests of the samples submitted
II is sufficiently proved that the Lake
county kaoiins will meet the requirements
OF the best American potterles, and they
BILE a full and constant supply Of Uniform
quality. 1t Is submitted. therefore, that
by keeping In stock. In depots at the pot
teries, kaolin Of regular brands, from
which potters might draw their demands
when needed, such convenience and saw
ing to them would be effected as almost
necessarily to draw nearly the whole Of
trade.
