Stable Resin - Draw downs have been aged 3000 hours in a weatherometer (equal to approximately 62 years of museum light exposure). The samples retained their solubility in mild solvents, showing that the resin is stable upon aging.

Fully saturated color - the high refractive index of the resin leads to colors as saturated as aged oil colors

Low solvent requirements - Because the aldehyde resin is soluble in solvents of low polarity, you can greatly lower your exposure to strong solvents while retouching paintings. If at any time in the future it is necessary to remove the color it will redissolve in mild solvents, to help protect the original work.

All colors light fast - only pigments of highest lightfastness are used (including modern substitutes for Alizarin Crimson, Indian Yellow, and Brown Madder)

Excellent working properties - we have applied our 20 years of artist paint formulating experience to these colors, so their working properties facilitate the work of retouching rather than make it more difficult.

Convenient size - all colors available in 15 ml jars
