TERRA-COTTA, BRICK, ETC. 
127 
in their report upon pottery at the Exhibition of 1851, givo 
a very full list of works, publications, and patents con 
nected with brick-making machiuery. Those specially inter- 
ested in this brauch of the subject may find in the above-cited 
authorities the most accurate available Information, at least 
from the European poiut of view.* 
Hoffmann’s Furnace. 
The great establishment for the manufacture of bricks in 
Vienna now has thirty-three of Hoffmanns patent riug- 
ovens ” or annular brick-kilns in use. Tliey are said to mark 
a new era in the history of the works, elfecting a great saviug 
offuel, and consequently increasing the profits. They are 
equally applicable to burning brick, lime, earthenware, cement, 
and gypsum. The inventor states that over one thousand are 
now in use, and claims to effect a saving of two-thirds of the 
fuel required by the old methods of burning. Inasmuch as a 
very good description of the apparatus has been given by Di. 
Barnard in Ins report on the Paris Exposition,! it is sufficient 
to direct attention to this furnace, which does not appear to 
have found favor in the United States. One objection given 
against its use is the greater scale upon which our brick 
manufacture is conducted. V hen a kiln of the 01 di naiv form 
is opened there is room enough for carts and horses to drive 
in and load with brick of auy desired kind,—either hard- 
burned, pressed, or soft, or " salmon brick.” This objection 
mio-ht, however, be readily overcome by making the cham- 
bers of greater size. 
Clay Pipes. 
The manufacture of clay pipes is a branch of ceramic ait of 
no small importance, industrially. The establishment of 
Messrs. McKlroy & Co., in Philadelphia, turns out about a 
thousand gross of pipes weekly. About twenty different 
styles are made, ranging in price from 85 cents to $1.35 the 
gross. A clay of peculiar excellonce is required.
