Gach is the term used to describe a plaster made from gypsum. Gach work involves applying of plaster on the walls of a building. Just before it gets dry, this plaster is cut into the required shape using tools like the steel cutter. Once the designs are completed, they are given a coating of yellow colored varnish. Leaves of gold metal are pasted over this varnish coating.
Gach work is usually used for embellishing the walls of a gurdwara. This art-form is used for creating decorative forms and also for writing selective verses from the Guru Granth Sahib. The best examples of this craft can be seen in the Golden Temple of Amritsar.
