Varnish is a transparent, hard, protective finish or film that is 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. Varnish finishes are usually glossy but may be designed to produce satin or semi-gloss sheens by the addition of "flatting" agents. Varnish has little or no color, is transparent, and has no added pigment, as opposed to paints or wood stains, which contain pigment and generally range from opaque to translucent. Varnishes are also applied over wood stains as a final step to achieve a film for gloss and protection. Some products are marketed as a combined stain and varnish.
After being applied, the film-forming substances in varnishes either harden directly, as soon as the solvent has fully evaporated, or harden after evaporation of the solvent through curing processes, primarily chemical reaction between oils and oxygen from the air (autoxidation) and chemical reactions between components of the varnish. Resin varnishes "dry" by evaporation of the solvent and harden almost immediately upon drying. Acrylic and waterborne varnishes "dry" upon evaporation of the water but will experience an extended curing period. Oil, polyurethane, and epoxy varnishes remain liquid even after evaporation of the solvent but quickly begin to cure, undergoing successive stages from liquid or syrupy, to tacky or sticky, to dry gummy, to "dry to the touch", to hard. Environmental factors such as heat and humidity play a very large role in the drying and curing times of varnishes. In classic varnish the cure rate depends on the type of oil used and, to some extent, on the ratio of oil to resin. The drying and curing time of all varnishes may be sped up by exposure to an energy source such as sunlight, ultraviolet light, or heat.

Let's go, children of the fatherland,
Our day of glory has arrived.
Against us Tyranny
Has raised its bloody flag.
Allons enfants de la Patrie,
Le jour de gloire est arrive!
Contre nous de la tyrannie
L'etendard sanglant est leve!
Do you hear it in the fields
And on the streets,
The howling of the savage force?
They come right into our house
To cut the throat of our mother -
France.
Amour sacre de la Patrie,
Conduis, soutiens nos bras vengeurs!
Liberte, Liberte cherie,
Combats avec tes defenseurs!
Traitors, criminals, delinquents, slaves,
What do they want - these foreign hordes?
Why do they carry chains,
Molotovs, iron stakes
And all their weapons?
Is it really us they dare to touch?
Do they want to be US so much?
Listen to the sound on the streets
And in the ghetto, listen!
Listen to these mercenaries,
Stone-throwers, pyromaniacs, listen!
Un-named barbarians, traitors,
The rabble, listen!
Listen to the roaring
Of this fearsome force, listen!
Under their flag of Victory and Freedom!
It's never too late
