Michael Harding Balsam Resin Glaze Medium will enhance the gloss & shine of your oil colours with a deep lustre. Michael Harding mediums are unique formulations based on ingredients dating back to the 13th century, using natural materials such as resins, waxes & balsams. This one combines Austrian larch turpentine, which is less prone to darken than others, with dammar resin & linseed stand oil, chosen for its elasticity & stability. Specially designed to complement Michael Harding’s oil colours, it contains no drying agents. You’ll find adding just 10-20% Michael Harding Balsam Resin Glaze Medium will be enough to add a rich depth of colour to your work. UK shipping by road only.
