Azure

Ingredients

Azure stone (Lapis lazuli), Arabic gum, Water

Preparation Steps

Original Recipe Text

The azure stone is thoroughly rinsed and finely grinded until it becomes very soft and round. It is then rinsed again to ensure cleanliness. Arabic gum is added to the powder to form a dough-like consistency. Water is then added drop by drop until the desired concentration is achieved (p. 12). If excessive water is used, the stone loses physical properties (p. 12).

Evidence

"To make the azure color, first the azure stone is thoroughly rinsed and finely grinded, in a way that it turns very soft and round, and again it is rinsed to be clean more. Then, Arabic gum is added to be formed as dough."

Remarks

Azure is used for jewelry, sculpture, murals, tile, and fiber dyeing. It is resistant to alkali but turns colorless and gray when exposed to weak acids. The mineral is highly resistant to sunlight (p. 12).
