tran and the United States departments. Considering
the various kinds of glass that used both for the
comforts Of life and the finer purposes of Arr there can
not be aid 10 be either varied or extensive exhbi'
ton There is much greater supply Of painted and or
namenta glass than of the plain article and the plate
glass seems only be shown in the mirrors in the room
We bad expected our country would have sent IN
larger collection Of crown. window and plate glass
Glass il an abstract term for composition of earths
which fuse TO 'orm transparent compound. This char
acter of usibily the only point which distinguishes
il from porcelain The latter composed Of silica and
enc clay never melts in the fire To convert those IN
gradients into glass it is necessary to sdd some earths or
metallic oxides which give il that property Such are
p,tasb soda lime oxide of lead, and few other bodies
The cause Of fusion appears to be an effect OF any one OF
these last bodies upon the original mixture OF cay aud
sand in dividing the silica sand between the aulnni
(cla,) and itself forming what is termed double icates
Thus crown OF window glass would be- slcate 6i soda

ash or lead are soft and more easily fusble Any one OF
these can be- substituted for the other when CORES

generally pure and IN powder, well mixed are placed IN
