Michael Harding Balsam Resin Glaze Medium will enhance the gloss and 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 and balsams. This one combines Austrian larch turpentine, which is less prone to darken than others, with dammar resin and linseed stand oil, chosen for its elasticity and 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.
