Megilp / maroger medium is simply the thixotropic gel resulting from the equal combination of mastic varnish and black oil.

Many of the media involved in Curry's work ( and other followers of Maroger ) bear no resemblance whatsoever to the modern mastic varnish / black oil recipe.

Maroger medium which is not made properly may contain a large amount of dirt and impurities from improperly filtered mastic varnish, or the black oil may be overcooked, both of which would contribute to darkening and weakening of the work.

A little more than one spoonful of " black oil " combined with even one spoonful of mastic varnish resulted in the " jelly " medium thought to be Megilp ( another name of Maroger media ).

The primary form of " Maroger medium " known today is black oil (" Giorgione's " medium ) and mastic varnish combined in approximately equal parts to form a gel.

Maroger medium ( or any other painting medium, for that matter ) should never be used as a final picture varnish, as Maroger requires reaction by admixture with oil paint in order to dry.

These products produce effects similar to, but not the same as those of real Maroger medium, which depends on specific chemical reactions between leaded oil, mastic resin, and turpentine ( the mastic varnish vehicle ).

Naturally the water is attracted to the layer of gum and salt created by the acid wash. Printing ink based on drying oils such as linseed oil and varnish loaded with pigment is then rolled over the surface.

A newspaper article printed in 1887 reveals the seriousness of his claim, stating the lab contained " eight thousand kinds of chemicals, every kind of screw made, every size of needle, every kind of cord or wire, hair of humans, horses, hogs, cows, rabbits, goats, minx, camels ... silk in every texture, cocoons, various kinds of hoofs, shark's teeth, deer horns, tortoise shell ... cork, resin, varnish and oil, ostrich feathers, a peacock's tail, jet, amber, rubber, all ores ..." and the list goes on.

Apart from stylistic closeness, their techniques are very similar as well, for example having paint applied thickly, using an oil varnish medium, in shadows and darker garments, but very thinly on flesh areas.

The building's old pine, along with the varnish on the floors, oil on the wood inside and a gas heating system all contributed to the blaze.

In the past, it had a rolling mill, foundries, machine shops, and manufacturers of varnish, brick, glass, lumber products, wire, hair, felt, and lubricating oil.

Finishes include but are not limited to: paint, varnish, bluing, browning, oil, and wax.

As a parallel with the earlier Charles Knight-designed sleeve-valved automotive powerplants, any RCV sleeve-valved model engine that is run on model glow engine fuel using castor oil as a small percentage ( about 2 % to 4 % content ) of the lubricant in the fuel allows the " varnish " created through engine operation to provide a better pneumatic seal between the rotating cylinder valve and the unitized engine cylinder / head castings, initially formed while the engine is being broken in.

In classic varnish the cure rate depends on the type of oil used and, to some extent, on the ratio of oil to resin.

Some systems use a drying oil varnish as described below, while others use spirit ( or solvent ) varnish.

Compared to simple oil or shellac varnishes, polyurethane varnish forms a harder, decidedly tougher and more waterproof film.

Polyurethane varnish may also lack the " hand-rubbed " lustre of drying oils such as linseed or tung oil ; in contrast, however, it is capable of a much faster and higher " build " of film, accomplishing in two coats what may require multiple applications of oil.

Calcium sulfonates additives are also added to protect motor oil from oxidative breakdown and to prevent the formation of sludge and varnish deposits.

This applies to short trips of under 15 km ( 10 mi ), where the oil does not get to full operating temperature long enough to burn off condensation, excess fuel, and other contamination that leads to " sludge ", " varnish ", " acids ", or other deposits.

Finally, the plate was dried and varnished using a varnish made from sandarac, alcohol and lavender oil.

Acrylic varnish should be applied using an isolation coat ( a permanent, protective barrier between the painting and the varnish, preferably a soft, glossy gel medium ) to make varnish removal and overall conservation easier.

This line includes thinner, linseed oil, safflower oil, stand oil, painting medium, fast drying medium, and impasto medium, as well as gloss varnish, matt varnish, satin varnish, and varnish remover.

He also seems to have been responsible for an improved, harder, recipe for the etching ground that coated the plate and was removed to form the image, using lute-makers varnish rather than a wax-based formula.

His father, Moses Berlinger ( 1873 – 1938 ), was a paint and varnish salesman.

Originally scientists thought that the varnish was made from substances drawn out of the rocks it coats.

The use of overall paint or varnish decoration on large pieces of furniture was first popularised in Venice ( then later throughout Italy ).

In 1952, the varnish layer over the background in the painting was evened out.

Finally, the surface was sealed with a transparent varnish.

Botts observed a dark stain upon the floor beside the reception desk and later claimed that she believed that the stain was varnish, and that Whitman was there to shoot pigeons.

Originally intended by Dr. Baekeland for a synthetic varnish, the new material was used by Seabury in making the world's first molding of organic plastics in 1907.

His favourite method in wall-painting was to lay in his compositions in fresco and finish them a secco with a mixture of yolk of egg and liquid varnish.

There has been conjecture that this wood was treated with several types of minerals, including potassium borate ( borax ), sodium and potassium silicate, and vernice bianca, a varnish composed of Gum arabic, honey, and egg white.

In the late 19th and early 20th centuries kauri gum ( semi-fossilised kauri resin ) was a valuable commodity, particularly for varnish, and was the focus of a considerable industry.

Pliny states that Apelles made a number of useful innovations to the art of painting, but his recipe for a black varnish, called by Pliny atramentum — which served both to preserve his paintings and to soften their colour, and created an effect that Pliny praises to no end — Apelles kept secret and was lost with his death.

In many of these plays, however, it was too obvious that a thin varnish of historic learning, acquired for the purpose, had been artificially laid on to cover modern thoughts and feelings.

23 July 2010 < http :// kids. britannica. com / comptons / article-206069 / paint-and-varnish >.</ ref > The ancient Egyptians were well acquainted with the art of varnishing, but its origin appears to be far east of there in India, China and Japan, where the practice of lacquer work, a species of varnish application, was known at a very early date.

Spar varnish ( also called marine varnish ) was originally intended for use on ship or boat spars, to protect the timber from the effects of sea and weather.

Lacquer may be considered different from varnish because it can be re-dissolved later by a solvent ( such as the one it was dissolved in when it was applied ) and does not chemically change to a solid like other varnishes.

In both cases the theory was the same ; the ink of the printed design would not soak into the varnish, so that in the washing process the design would tend to flake off, forming a telltale pattern on the washed stamp.

The gum of Xanthorrhoea australis was used for carriage varnish.

Originally it used beeswax, oil of spike lavender, spirits of turpentine, elemi resin and copal varnish, and was complex both in preparing the wall surface and applying the paint.
