Dammar varnish(Dam) is a varnish made by dissolving dammar gum in turpentine.

Damar gum is a resin obtained from the tree family Dipterocarpaceae in India and East Asia.

It was introduced as a picture varnish in 1826.

Copal varnish(Cop) is a varnish produced by boiling ground copal stone in linseed oil at high temperatures.

Copal is a resinous substance in an intermediate stage of polymerization and hardening between more viscous resins and Amber. Amber is fossil resin or tree sap that although not mineralized，it is sometimes considered a gemstone.

Copal varnish was first used in the late middle ages.

Turpentine(Turp) is the resinous exudate or extract obtained from coniferous trees，particularly those of the genus Pinus.

The molecular formula is C₁₀H₁₆.

It is mainly used as a solvent and has been produced since antiquity.

Mars noir(Feo) is an iron oxide pigment，with high lightfastness.

The molecular formula is Fe₃O₄.

It was developed in the 20th century.

Egg yolk(Egy) is yolk from a henn's egg. It can act as binder for pigments.

The characteristics of egg tempera are very unique. It requires a different technique than gouache or oil. 'Brush load' -meaning the amount of paint suspended in the brush when going from the recipient to the painting，is an important aspect of developing feel for the handling of tempera. It requires premeditated and accurate handling and is therefore less suited for expressive gesture. The finished look is incomparable to any other medium. The resulting paintwork is very brittle and must therefore be covered with some type of varnish for protection.

Egg yolk has been used as a binder since the earliest times.

Distilled water(H₂O) is useful whenever water must be added to any mixture，it is much cleaner and makes for a smoother mixture than tap water or drinking water.

Vinegar(Vi) is comprised of acetic acid and water，and is an very clean，crisp liquid. Acetic acid is the result of a fermentation process.

The molecular formula is CH₃COOH.

Prussian blue(Prbl) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts.

It has the molecular formula FeIII₄[FeII(CN)₆]₃.

Prussian blue was the first modern synthetic pigment.

Blue clair perm(Pcbl) is a phthalocyanine derivative.

Phthalocyanine (H₂Pc) is a large，aromatic，macrocyclic，organic compound with the formula (C₈H₄N₂)₄H₂.

Phthalocyanine was first synthesized in 1933.

Azurite blue(Azbl) is composed of mineral basic carbonate of copper，found in many parts of the world in the upper oxidized portions of copper ore deposits. Azurite mineral is usually associated in nature with malachite，the green basic carbonate of copper that is far more abundant.

It has the formula Cu₃(CO₃)₂(OH)₂，with the copper(II) cations linked to two different anions，carbonate and hydroxide.

Azurite was the most important blue pigment in European painting from the fifteenth to the middle of the seventeenth century.

Blue oxide(Oxbl) is a blue pigment made by sintering cobalt oxide with Aluminum Oxide.

Chemically，cobalt blue pigment is cobalt oxide-aluminium oxide，or cobalt aluminate，CoAl₂O₄.

It is extremely stable and historically，has been used as a coloring agent in ceramics，jewelry，and paint.

Terra rossa(Tr) is an earth pigment containing iron oxide and manganese oxide.



It was one of the first pigments used by humans.

Caput mortuum(Cam) also known as cardinal purple，is the name given to a purple variety of haematite iron oxide pigment.



The name for this pigment may have come from the alchemical usage，since iron oxide (rust) is the useless residue (caput mortuum) of oxidization. It was originally a byproduct of sulfuric acid manufacture during the 17th and 18th centuries，and was possibly an early form of the copperas process used for the manufacture of Venetian red and copperas red.

Kalk rood(Chr) is a pigment of wich the composition is known only to the manufacturer.

I have no further information on this pigment except that I bought it under the name 'chaux rouge' at Le Lion Bruxelles.

Titanium white(Tit) is the most brilliant white available to artists in the entire history of art.

The molecular formula is TiO₂.

The pigments natural ore is rutile (titanium dioxide) and manufacturing it as a pigment presented difficulties and it was not until 1921 that American and Norwegian companies began to develop its production for painting.

Vermillion imitation 1(V) is an organic pigment，in this case a mixture of 'studio red'，'hansa yellow' and 'blanc fixe' from Kremer.

Cadmium Lemon(Lem) is the inorganic pigment that is a sulfide of the metal cadmium.

The molecular formula is CdS.

The general commercial availability of cadmium sulfide from the 1840s led to its adoption by artists.

Vert lion(Grl) is a pigment of wich the composition is known only to the manufacturer.

I have no further information on this pigment except that I bought it under the name 'Vert le lion' at Le Lion Bruxelles.

Mars rouge(Reo) is a synthetically prepared red iron oxide pigment.

The molecular formula is Fe₂O₃.

By the 18th century，synthetic red iron oxide pigments were being made in a laboratory setting. Called Mars Red，these pigments were found to have all the properties，including durability and permanence，of their natural counterparts.

Burnt umber (lefebvre)(Bu) is a brown or reddish-brown earth pigment that contains iron oxide and manganese oxide.

It is made by heating raw umber，which dehydrates the iron oxides and changes them partially to the more reddish hematite.

The first recorded use of burnt umber as a color name in English was in 1650.

Sienna pale(Sic) is an earth pigment containing iron oxide and manganese oxide. In its natural state，it is yellowish brown and is called raw sienna.



It was one of the first pigments used by humans.

Champaign chalk(Cham) is a soft，white，porous，sedimentary carbonate rock，a form of limestone composed of the mineral calcite. It has a slightly yellowish tint，hence the name.

The molecular formula is CaCO₃.

Hide glue(Size) is an organic colloid of protein derivation used as an adhesive.

Size is derived primarily from collagenous material present in animal hide.

The first known written procedures of making animal glue were written about 2000 BC.
