Ricciardelli’s products are
classified as “majolica or faience” that means products obtained by objects
that during the firing result of a porous and absorbing structure with
different colours for oxides in the clay. These products are covered by a glaze
and transparent enamel. Temperature of firing: 900° C – 950°C.
First phase: the clay
take shape and the “biscuit”
Ricciardelli workshop buy the “biscuit” from
“tornianti” (who lathes the clay in order to shape it). The term “biscotto”
means an rose-coloured object, that it is shaped with clay and firing for the
first time at 950 e i 980 °C.
Second phase: glaze
and décor
In the workshop, the “biscuit” is immersed in a
covering, called “smalto” (in English “glaze”). When the glazed object is dry,
Ricciardelli paints it with a thin brush.
The colours used are powder but adding water it
is possible use brush to paint.
If you touch the product now it is like covered
by powder!
Third phase: the second firing
The painted object
is put inside a kiln for the second time at 920°C, previously application
of “cristallina” in order to get the product bright.
After firing the
colour are different than they are before it, for example blu is violet
before firing.
Fourth phase: the
third firing
For decor with application of gold, silver or other iridescence it need a
third firing, as result we can use the term product in third firing to
indicate, for example, décor “Melograno” (in English “pomegranate”) or "Arabesque".
