All pieces are modeled manually in soft clay on a wheel or molded by hand and allowed without forced processes.
It begins with the pieces being fired in electric kilns at 960º.
They are called chacotas or biscuits. Then follows manual glazing in which the pieces are dipped into baths with liquid glaze also known as pewter salt.
All the painting it's done in free hand with brushes, using colours traditional to Portuguese faience, e.g.: blues, yellows, manganese, olive and copper green.
After being painted, a second firing takes place when, quite often, nuances in colour appear. This reflects the influence of each painter. Colours can be softer, harder sometimes shiny, other times more opaque.
Occasionally pieces show hairline cracks in the glazing, which are called crackling, this is caused by the clay, glazing or kiln temperature. This is quite typical in traditional, antique faience.
We can sum up by saying that all the above mentioned characteristics confer with craftsmanship.
