The 225ml tube is where Michael Harding's oil paints make the most economic sense for painters who work at scale. The same formula as the 40ml — no fillers, no extenders, the same pigment load — but at a significantly lower cost per millilitre. A painter working through a 225ml Titanium White in a month of serious studio work will notice the difference in running costs immediately. The range in 225ml covers 125 colours across seven price series, from Series 1 earth pigments through to Series 7 genuine Lapis Lazuli. The series structure is transparent about pigment cost — you're paying for what's in the tube, and the pricing reflects that directly. Consistency and pigment concentration are identical to the 40ml. Long-oil paints with a buttery texture and no added extenders — which matters for glazing, where any filler will reduce the transparency of a glaze layer. Drying times follow the same pattern: earth pigments and lead whites are faster; cadmiums and cobalts are slower. Store tubes horizontally with caps tight; the high pigment load means separation can occur in tubes stored upright for extended periods. The 225ml size suits studio painters working in oil regularly — portraiture, landscape, large-format work, or any practice where paint consumption is high. Less practical for location work.
