Clear shellac(Shell) is a resin secreted by the female lac bug on trees in the forests of India and Thailand. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac，which is used as a brush-on colorant.

Shellac is a natural bioadhesive polymer and is chemically similar to synthetic polymers，and thus can be considered a natural form of plastic.

The earliest written evidence of shellac goes back 3000 years，but shellac is known to have been used even earlier.

Ethanol(Eth) is ethyl alcohol，the same type of alcohol found in alcoholic beverages.

The molecular formula is C₂H₅OH.

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

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.

Ultra violet(Uv)

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

Bic blue pen ink(Bic) is normally used to refill ink pens.

It is manufactured by the company Bic. Opposed to pigments，dyes are colored substances that chemically bond to the substrate to which it is being applied.

This is a commonly available product in stores.

Euro coins(Eur) of 1，2 and 5 are used for oxidation in vinegar to create a brown color.

They consist of 89% copper，5% aluminium，5% zinc and 1% tin.

Madder(Mad) is a herbaceous perennial plant species belonging to the bedstraw and coffee family Rubiaceae.

The botanical name is rubia tinctorum.

The roots can yeild a strong，permanent deep red color used in dyes and lakes. In order to draw out the red color，alum is often used.

Aluminium salt(Alum) is an aluminum based salt crystal readily available in drug stores.

Alum is a type of chemical compound，usually a hydrated double sulfate salt of aluminium with the general formula XAl(SO₄)₂·12 H₂O.

Alum was the most common mordant used in the dye industry in the middle ages.

Gall nuts(Gal) are hard nutlike galls that forms on varieties of oak (Quercus cocinea a.o.) in response to the developing larva of a gall wasp. It is used as a source of gallic acid and tannin. It differs slightly from Aleppo galls found in Asia and southern Europe but serves the same purpose.

Tannic acids are organic compounds that contain a 3，4，5-trihydroxybenzoic acid moiety. Gallic acid exists as a solid，slightly soluble (in water)，and a weakly acidic compound (based on its pKa).

Has been harvested for thousands of years as a concentrated source of tannins for use in high-quality inks，in medicine，etc.

Fish glue (flakes)(Fish) is a traditional woodworking glue with a strong bond that dries crystal-hard.

It is made from fish blatters.

It was widely used by carpenters and bookbinders in the past.

Marble dust(Marb) is powder from metamorphic rock composed of recrystallized carbonate minerals，most commonly calcite or dolomite

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.

Plaster(Plast) is produced by heating gypsum.

The molecular formula is CaSO₄.

It is commonly used for plaster casting.
