A thangka, variously spelt as thangka, tangka, thanka, or tanka, is a Tibetan Buddhist painting on cotton, silk appliqué, usually depicting a Buddhist deity, scene, or mandala.
Thangka is also known as scroll painting. Initially, designs are drawn on a gelatin paper using pen. The cloth is tied to an iron or wooden frame using cotton threads. To avoid pores on the cloth, a mixture of distemper and gum boiled with water is applied on the cloth before painting and dried.
