Illustrated plate taken from the "Catalogue of Baking Dishes"

At the end of the 19th century, Richard-Ginori patented a particular type of mixture, which, due to its high resistance to fire and especially to temperature changes, was called “Pirofila.” 

The catalog from which this plate is taken was published in 1901 and is entirely dedicated to this special porcelain, whose features were illustrated and ideal for the production of ovenware. The price lists included pots, casseroles, pans, kettles, creamers, coffee machines, molds, and cake tins of various shapes and sizes, as well as complete tea or coffee sets and breakfast cups. 

Pirofila products could be made in plain white, glazed in brown, or with a burnt finish. For types intended to be brought to the table, it was also possible to decorate handles, grips, borders, or other details in gold. Each model had an identification number with available sizes and capacities, in addition to the price for each individual piece.
