It is a modern painting technique born
in the Scandinavian Countries. The motifs of the decorations
are often abstract or very stylized. What characterizes this
technique is the possibility of modifying the surface of the
porcelain with hollows and reliefs. That is realized with
the use of special compounds which allow to chip off the "cover"
or glaze of the porcelain and to obtain biscuit zones more
or less deep and irregular or to create some reliefs in which
it is possible to set glass pearls, murrine, river pearls.
Often the colours are replaced by the lustres, solutions with
a metal base, which confer to the surface of porcelain a particular
brilliance and iridescence.
The bright gold is used to gild hollows and reliefs, to adorn
zones covered with lustres, to create particular effects.
