  Varnish - Wikipedia, the free encyclopedia
Varnish is traditionally a combination of a drying oil, a resin, and a thinner or solvent.
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.
Although not a particularly durable varnish, shellac is sometimes used as a primer or sealer for paint or varnish, or as a finish by itself, as in french polishing, a difficult technique that produces an inimitable sheen on wood i.e.

For oil varnishes a hard gum or resin, often a fossilized plant exudation such as kauri or copal, is dissolved in oil (commonly linseed oil or tung oil) and is diluted with a volatile solvent such as turpentine.
Spirit varnishes are commonly made of soft resins or gums, such as shellac, dammer, mastic, or sandarac, dissolved in a volatile solvent, e.g., alcohol, benzene, acetone, or turpentine.
Among the varnishes named either for their constituents or for the proposed use are japanner’s gold size, cabinet, carriage, bookbinder’s, patent-leather, insulating, photographic, shellac, and copal picture varnish.

 Summary: Varnish
Tone, intensity, and color of the varnish depend mostly on climate variations (e.g., precipitation) and on the relative age of the exposure of the rock surface.
Layers of varnish are relatively thin, commonly 0.005 to 0.5 mm thick, but thickness varies from locality to locality as well as over the surface of a single stone.
Varnish commonly forms on rocks that contain little or no iron and manganese, indicating that these elements are carried to the rock surface by wind, water, or both.

 Varn
It may be considered inadequate by the experienced varnisher because it is not comprehensive, and by the beginner because it is not a step-by-step do-what-you're-told instruction manual.
After varnish is applied and spread over the surface with a brush, it is usually brushed repeatedly in one direction and 'layed off' in a perpendicular direction (laying off is brushing with the brush at a shallow angle to the surface).
While the varnish coat is drying, if a hair or other debris falls onto it and gets stuck, one deals with it only after the varnish is quite tack-free (non-sticky to the touch) and firm, but not fully dry.

Desert varnish is a thin coating (patina) of manganese, iron and clays on the surface of sun-baked boulders.
Instead, the rocks are coated with "desert varnish," a reddish layer of clay and iron oxide precipitated by remarkable bacteria.
In fact, dating of varnished surfaces is of enormous importance to the study of desert landforms and to the study of early humans in America, since many artifacts lying on the ground become coated with desert varnish.

For the varnish to properly adhere, the hull, not just the air around the boat, must be a minimum of 65 degrees Fahrenheit.
Varnish does not like anything waxy and will creep away from it after application, so make sure the surfaces are clean.
If you are varnishing only the deck, or the hull, you can separate the two by taping and masking the line where the topsides sheer plank meets the lower edge of the covering board and where the forward edges of the transom planks meet the after ends of the hull topsides planks.

Spar varnish is a term that applies to an exterior varnish that is suitable for finishing the spars on a boat (masts, booms etc) and other woodwork that is troublesome to maintain because of the severe reflected sunlight and expansion and contraction and moisture and other weather that boats are exposed to.
Varnishes ceased being what they were in the "old days" by the time the Clean Air Act Standards came into place in the early 1970's.

 Varnish Application Guidelines
If varnishing water-soluble paints, including watercolor, gouache and tempera, the isolation coat must be sprayed on in very light layers to avoid solubilizing the paints, which could cause loss of distinctness of the underlying image.
Satin and matte varnishes tend to be thicker in the bottle than the gloss varnishes and may require additional dilution.
The varnish must be removed, the surface sealed to reduce absorbency (apply gloss varnish), followed by application of a reduced sheen varnish.

Varnish as a finish is really quite old, being used in the Orient centuries ago.
Since varnish is a more durable than lacquer and was in use before polyurethane was invented, it tends to be favored by many old-timers, if for no other reason than it works.
One plus for varnish is that it is it's own sealer; the first coat on a piece after staining can be varnish, either full strength or thinned with paint thinner.

 Varnish
The appeal of well-maintained, varnished wood trim on boats is hard to deny.
Good varnishes are designed to address both stretch/shrink cycles and UV degradation, but eventually the two forces in combination will break down varnish and cause it to fail.
Once inside, it is trapped and causes the wood to swell and discolor, which eventually causes the varnish to lift and peel from the wood.

Conversely acrylic varnishes are high molecular weight, which means the varnish fills in the geography of a painting.
If you put one layer of varnish on a painting and only parts of the painting become glossy, then some areas are absorbent and they have absorbed the varnish into the surface.
If the varnish is old then we recommend that you take the painting to a conservator or paintings restorer since it may require acetone to remove the varnish.

Varnish is damaged by sunlight, water, and abrasion; and those are three things that boats have in abundance.
I have to schedule my varnish work so I complete the preparation work on one day, and start varnishing early the next day, so I can varnish in the 7:00 to 10:00 time slot, before the sun is high and the air is hot.
I realize that varnishing in the middle of the day results in a skin forming too fast, trapping solvents which produces rough surfaces and which soften the old varnish and cause blisters.

 Desert varnish - Wikipedia, the free encyclopedia
Desert varnish, or rock varnish is a dark coating found on exposed rock surfaces in arid environments.
Desert varnish forms only on physically stable rock surfaces that are no longer subject to frequent precipitation, fracturing or sandblasting.
The varnish is primarily composed of particles of clay along with iron and manganese oxides.

 Gamblin Artists Colors - Frequently Asked Questions - Varnish
When the varnish is starting to set up, if you continue to brush it then you will microscopically roughen the surface and it will be less glossy.
So if you do not like the way any varnish looks now, consider adding a line to the stretcher bars or on the back of the panel that says: "ok to varnish in the future." This way you can let conservators of the future add a varnish layer if appropriate.
But a glaze layer is not reversible and varnish is. The glaze layer becomes a permanent part of the painting.

This varnish seems to produce a slightly better gloss and is also more abrasion resistant (it is certainly harder to wet sand than z*spar).
It is not unusual to get a varnish sag or drip in every coat you put on (only practice and knowledge of varnish behavior will improve it).
The fresh varnish will refuse to feather and blend seamlessly into the 'older' coat and more sags are sure to follow.

This matt varnish must only be used after you have GLOSS varnished the figures first with Humbrol Gloss polyurethane varnish.
After mixing up the matt varnish always try it out on an old figure to check the level of mattness I keep several old figures nearby which languish under hundreds of coats of varnish, but it beats making a mistake with a figure I've just painted.
Can Spray varnishes are OK if you have a lot of figures to but I'm never happy with their inconsistency of finish - sometimes matt - sometimes not, better to use an airbrush applied varnish.

Desert varnish is a dark coating on rocks found in arid regions.
Many petroglyphs (125K) are created by chipping through a dark coat of desert varnish to expose a lighter colored underlying rock.
At the contact with the desert surface, a dark ground-line band develops containing a thick layer of varnish which essentially completely coats the region of the rock in contact with the top layer of the soil.
