Casein colors

Casein colorsCasein paints are wall and ceiling paints whose binder is pure natural milk protein (= casein). In ancient Egypt, paints were already produced and processed from milk and earth pigments. The same can be seen in ancient Hebrew texts. Wall paintings in the Sistine Chapel (Secco technique) owe their durability to the same ancient recipes.
Instead of milk, quark was later used, which contains three times the amount of casein (about 12%).

By using milk and quark, the colors must always be prepared fresh. They can be kept for only hours to a few days
Modern casein inks are produced as powder and contain casein in dry form. This extends the shelf life to several years Preservatives are superfluous, transport weight and thus transport costs, packaging waste are reduced to a minimum.
What is new is the use of vegetable protein Plant casein as a binding agent Plant casein comes from protein-collecting plants such as peas, lupins, beans or other legumes. Milk casein is produced by treating fresh milk with acid or calf rennet, whereby the protein flocculates and is then filtered, dried and ground The protein retains its edible quality. Used alone, casein is not a binder; it lacks adhesive strength. Only in the presence of alkalis does the casein turn into a glue, the protein is "broken down" Suitable are: Potash, soda ash, bicarbonate (baking soda), staghorn salt, borax or hydrated lime.
Unlike most other color binders, casein exerts almost no influence on the appearance of pigments and fillers. This allows pigments to shine with their unique typical brilliance Casein paints are absolutely biologically harmless throughout their entire product cycle (extraction, use, disposal). Color residues can even be composted
