The Pegasus Vase, Etruria factory,
Staffordshire, England, AD 1786, a
masterpiece of the potter's art from the
Wedgwood factory. The body of the
vase is made of pale blue jasper, and the
relief decoration, handles and Pegasus are
of white jasper. Jasper is a type of
unglazed stoneware that can be stained
with colour before firing. Josiah
Wedgwood I (1730-95) perfected the
technique by 1775 after a number of
experiments to produce a new clay body
for the making of gems.
