Irish glass does not feel harsh or cold like most English or foreign,
but gives a sense of soft warmth to the touch. There is something of
the same distinction as between porcelain and earthenware, though not
nearly to such a marked extent. One has to acquire a knowledge of
it by experience; and though the tyro may at first perceive little
or no variation between the feel of Irish and English glass, if he
will cultivate his sense of touch by handling authenticated pieces of
both varieties, he will soon find that there is a small but perfectly
distinguishable difference between them.
