History

This technique began to be used since the middle of the 18th century , especially in France , at the Sèvres factory and in Italy , at the Royal Fábrica di Capodimonte in Naples .

At this time the statuettes and groups of pastoral scenes became fashionable. In the 19th century many dolls were made in biscuit.

Elaboration

The oven to make Biscuit must be 900 to 1,000 ºC and an indispensable condition is that the air must circulate to produce an acceptable oxidation.

characteristics

The ceramic biscuit is white, matte and very fragile, so it is only used as a decorative element in figurines and other objects. It is not appropriate for dishes.
