The Persian lustre develops in the glaze and a special firing
which uses reducing atmosphere in cooling.
Unlike other preparations on the market that can fade over time,
despite being cooked over the glaze, the Persian luster is absolutely unalterable in terms of texture and color.
The colors of the Persian-type lustres are developed using the "salts" of metals, ie chlorides, nitrates and sulphates.
Probably discovered by chance by the Persians about 1000 years ago,
these lustres are complicated to make but very beautiful!..
