सरुको हरफ - अंग्रेजी - varnish

The coloured varnish sitting on top of the ground, and wears off with time, is meant to enhance the appearance of the wood, but can be detrimental to the freedom of vibration of the plates if it is applied too thickly or has too hard a consistency. the varnish should ideally be thin enough and light enough not to constrict the instrument. The myths associated with varnishes never cease to inspire the imagination. The "lost secret" of varnish making has a pleasing allure to many.
