BLOCKX oils are crafted in Belgium using the purest, highly lightfast pigments, combined with carefully selected oils most often poppy seed oil to ensure exceptional luminosity and long-term colour stability. Each pigment is processed individually at variable speeds, then slowly ground to avoid heat, preserving chromatic intensity and pigment integrity.
The majority of BLOCKX oil colours are mono pigment, formulated without fillers or unnecessary additives, resulting in an extra fine paint with remarkable concentration and vibrancy. Traditional grinding on prophyry stone, similar to hand grinding, ensures optimal fineness and smooth application.
With a lightfastness rating of 7–8 on the Blue Wool Scale, BLOCKX oils are trusted by professional artists worldwide. Four generations of craftsmanship stand behind every tube, staying true to the founding philosophy: only the best pigments, only the best methods, no compromise.
