4 effects you can achieve with Winsor & Newton’s Mediums for Oil Colour

Oil Painting Mediums

Artist Nick Scrimenti recently proclaimed his love for Winsor & Newton’s range of Mediums, discussing the myriad ways they transform his work. Inspired by his pragmatism and exploration beyond his own immediate palette, we have chosen four Mediums techniques that could expand your oil painting horizon.

After a layer of Artists’ Oil Colour has dried or semi-dried, you may choose to glaze it by adding a thin, oily transparent layer of paint. As light travels through the glaze, it’s reflected off the opaque layer beneath. In short, it makes the painting glow. 

Often a lengthy process of applying layer upon layer, glazing is one technique that benefits from a professional-grade medium, like Liquin Original or Blending & Glazing Medium. If you choose to work with Liquin Original, you’ll notice an improvement in drying times, flow and less visible brush strokes. Likewise, Blending & Glazing Medium improves transparency and depth, before drying to a durable, glossy finish.


Scumbling allows you to build up multiple layers of ‘broken’ (speckled or deliberately cracked) colour. The base layer peeks through, giving a sense of depth, texture and colour variation to your work. 

While the technique can be skilfully achieved with either opaque or transparent colours, the effect is stronger when opaque shades are used. The base layer needs to be thinned with Liquin Original, as well as being lighter than the upper layer.  


Sometimes, blending a light area of oil paint into a dark area does not give off the smoothest glow. Many artists choose to add incandescence to their finished piece by using a stippling effect. 

For stippling, the best brush to use is one of the Artists’ Hog Brushes. Its stiffness, when used with thick, viscous colour, creates a strong, stippled texture. In order to get the most professional finish, mix your oil colour with Liquin Oleopasto, which will both extend and thicken Artists’ Oil Colour.  


Coming from the Italian for ‘dough,’ impasto is a particularly popular technique for exploring texture. By applying thick layers of paint with the right brush and Mediums, brush strokes can remain plainly visible and create an highly textured effect. Rembrandt, for instance, employed this technique to pick out jewels on a costume; while Van Gogh used it for expressive purposes. 

When seeking an impasto effect, Liquin Oleopasto adds texture, thickens rapidly and increases transparency. Liquin Impasto Medium, too, is designed to retain crisp texture. Whether you use Liquin Oleopasto or Liquin Impasto, your painting will be touch-dry in 1-6 days, making both Mediums particularly useful when layering for an ultra-thick impasto effect. 

Whether exploring glazing or scumbling; stipling or impasto, be sure to refresh your knowledge of the three rules of oil painting.
