Gilding currently means to draw beautiful patterns of plants or geometrical shapes on the margins of books. At the beginning, golden color was used in this art and this is why they called it “tazhib” gilding. Other colors like azure, blue, green, vermilion, and turquoise have also been used along with gold.
The Iranian gilding art has no parallel in the world. Europeans have their own style of gilding, which is quite different from the Iranian gilding.
