Arabic gum is the binder traditionally used for watercolor. It is made from acacia and is the oldest of the gums.
Dammar gum is a resin secreted by a tree in the Indonesian Islands. It has been used since the 19th century in painting for the manufacture of varnishes and painting mediums. It produces a natural, transparent, satin-to-gloss finish. Used as an adjuvant in oil paint and wax, it is diluted in the essence of turpentine.
Casein (milk protein) is a natural fixative for limewash paints to which it provides matte and velvety. Used by artists from the Middle Ages, it is perfect for frescoes and icons. A little neglected over time, it returns to fashion especially in the decoration of painted furniture.
Glue of animal origin, it has a powerful tackiness and can be used in many ways (sealant, glue, coating, paint, etc). The rabbit skin glue is known for its properties of flexibility and finesse.
