additional informations

kama's walnut oil is a first-pressed, semi-drying siccative oil. Semi-drying oils are a subcategory of siccative oils, defined as containing a lower concentration of the free fatty acids that are responsible for the chemical reaction allowing siccative oils to dry : to pass from a liquid to a solid state via a complex chemical reaction. This oxidation reaction is not only responsible for the drying of our paints but also for their aging since it continues beyond that. drying, thus causing the yellowing of oil colors in the years following the completion of the work.

Since these fatty acids are present in lower proportions, walnut oil, like other semi-drying oils, oxidizes and ages at a much slower pace thant linseed oil the traditionnnal binder of oil paints and mediums.

In short, the colors and mediums made from walnut oil will be more vibrant and will yellow less with time: this is the reason we have selected it to manufacture all of the KAMA oil colors.
