Answer:
Varnish is a type of wood-finishing material that is made by dissolving gum in linseed oil. It is applied in the form of films or skins onto wood surfaces using a brush or spray. Its primary purpose is to provide protection to the wood and enhance its aesthetic appearance.
When applied onto wood, varnish forms a transparent or translucent protective layer that shields the surface from scratches, moisture, and other elements that can damage the wood. It also helps to prevent the wood from fading or discoloring due to exposure to sunlight.
In addition to offering protection, varnish also serves to beautify wood surfaces. It provides a smooth and glossy finish that enhances the natural color and grain patterns of the wood. Varnish can be applied in different thicknesses and can be tinted or colored to achieve various desired effects.
The gum dissolved in linseed oil acts as a binder that helps the varnish adhere to the wood surface. Linseed oil also provides some level of water resistance and flexibility to the varnish film. Different types of gums or resins, such as dammar or shellac, may be used to create varnishes with varying properties and characteristics.
Varnish is a popular wood-finishing material that offers both protection and aesthetic enhancement for wooden surfaces. Its versatility and ease of application make it a widely used choice for sealing and beautifying furniture, cabinetry, flooring, and other wooden objects.
