ntered than in common flint glass, and therefore incapable of
being affected by any articles of food contained or prepared in such
vessels. With these materials, either in their natural white or
variously coloured--black by manganese, blue by cobalt, brown and buff
by iron--he produced imitations of the Etruscan vases, and of various
other works of ancient art, such as the world had never before
seen--such as no subsequent artist has ever attempted to rival. His
copies of the Portland vase are miracles of skill; and the other
specimens of similar works may give some idea of the many beautiful
works that were produced in his manufactory. In table ware, for many
years he led the way almost without a rival; but the immense demand
occasioned by the successive improvements of this article, which first
put down the use of delft, and then of pewter, gave ample room and
encouragement to men of capital and skill to enter the field of profit
and competition. Much good has hence resulted; many subordinate
improvements have been effected and are almost daily making; and a new
variety of ware, called ironstone, has been invented, and so rapidly and
judiciously improved, that, in appearance and in many of its intrinsic
properties, it bears a close resemblance to the older and coarser
porcelains of China itself.

I shall conclude by a summary account of the manufacture of the best
table ware; for a considerable part of which I am indebted to notes
taken by Captain Bagnold, when visiting a pottery, inferior, perhaps, to
none in the country.

The materials of the Staffordshire ware are calcined flints and clay.
The flints are burnt in kilns, and then, while hot, quenched in water,
by which they are cracked through their whole substance. After being
quenched they are ground in mills with water. The mill is a hollow
cylinder of wood bound with hoops, and having a bottom of blocks of
chert, a hard, tough, siliceous stone: the mill-shaft is perpendicular,
and has two horizontal arms passing through it cross-wise. Between these
arms are laid loose blocks of chert, which are moved round on the
bed-stone as the arms revolve, and thus grind the flint with water to
the consistence of cream.

The clay, from Dorsetshire and Devonshire, is mixed with water, and in
this state is passed through fine sieves to separate the grosser
particles. The flint and clay are now mixed by measure, and the mud or
cream is passed through a sieve in order to rend
