Varnish
Varnish
Varnish (/ˈvɑːrnɪʃ/) is a transparent, hard, protective finish or film primarily used in wood finishing but also for other materials. Varnish is traditionally a combination of a drying oil, a resin, and a thinner or solvent.
Etymology
The term "varnish" comes from the Middle English term "varnisch," which is derived from the Old French "vernis," and ultimately from the Latin "veronix," meaning "resin."
Types of Varnish
There are several types of varnish available, each with its own unique properties and uses. Some of these include:
- Spar Varnish: This type of varnish is designed to protect wood from water, sunlight, and temperature changes.
- Polyurethane Varnish: This is a type of varnish that is resistant to water, heat, solvents, and other chemicals.
- Acrylic Varnish: This is a type of varnish that is water-based and non-toxic, making it safe for use on children's toys and furniture.
