Terzo Fuoco (fired three times) is the enameling technique for thick enamel in combination with gold. It requires that a piece be fired three times with very careful temperature control; one for the regular annealing, one for baking the enamel and one for firing on the gilding. The technique is widely in use in the Czech republic where most raised enamel pieces originate from; it is technically identical to the Italian produced items, though stylistically there are some differences.
