lis now about year since general
description of NJ. de la Bastie's method
OF toughening or tempering glass, and
| the special characteristics of the mate
rial produced, appeared in our columns.
At that time, and for some months
subsequently, the process was carried
on at NJ. de Ia Bastie's works at Pent
d'Ain, near Lyons, upon a small scale
only. Having thoroughly demOestra-
ted that process could be carried out,
practically and commercially, with
both success and profit, glass works
were purchased in which the produc-
| tiOn OF glass articles for domestic use
had hitherto been carried on upon the
ordinary principles of manufacture.
These works were rearranged to suit
the new process of ftempering, and some
two months were consumed in excess.
This M. de Ia Bastie has succeeded in
doing, and the works were fairly start.
ed in February last. A careful inspec-
tiOn of the works, which, through the
courtesy of NJ. de la Rastie, we were
recently able to make, leads US to the
conclusion that a more simple and,
with ordinary care, mere certain pro-
cess is not to be found in the whole cir.
Gle of the industrial arts.
Besides the works of Choisy le Roi,
M. de Ia Bastie still keeps his expert
ment WORKS at Pont d Ain in operation.
There, however, the glass is purchased
from makers, and reheated and tenn
pered. At Pont d. Ain there are in all
eleven furnaces, two single and two
for 70 Iofn rl., nd
five other kinds OF glass. There are al
so some similar furnaces for tempering
watch glasses. The plates of glass at
present tempered are of various sizes,
the largest measuring eighteen inches
by twelve inches; large sizes will, how
ever, soon be tempered, and new ma
chinery is in course of construction tor
that purpose. 1t is also intended to
put up two furnaces at POpt d'Ain for
the manufacture of tempered glass in
the same way as at ChOisy. Besides
the two factories of NJ. de Ia Bastie
there are three others in France at
which his process of tempering has been
adopted. These are the extensive glass
factories of Lyons, Vierzon and Aub-
dervilhers, near Paris. At these works
M de Ia Bastie has such orders eXecu-
ted as he receives and which he is una
BILE to execute, owing to the present
comparatively limited capacity of his
own establishments. These are the
subsidiary arrangements to which we
alluded when referring to the necessi-
ty for extending the works at Choisy.
The proprietors of twelve other works
in France are now in communication
with M. de la Bastie, with the view of
adopting the manufacture of tempered
glass upon his principle. The temper
ing process has also been introduced
into several countries besides that
which gave birth to its inventor. In
Germany for example, there are a
number of works at which tempered
glass is being made. In Ameri- |
ca it has taken good root. The process |
has been six months at work in Brook |
lyn, and has been adopted at works In |
Pittsburgh and Boston, and at the
Bellaire works and the Wheeling |
works in Ohio, as well as at other
smaller cities.
