This report reviews a few of the more popular oil painting mediums, their purpose, and a few advice on how best to use them. The purpose of adding these materials to your own oil paints would be to alter the behaviour of the paint during application and affecting results after the painting dries. Behavior describes the way the paint comes off the brush and slips on the surface, the way that it covers either the surface or succeeding layers, and precisely how it feels as you apply it.
Brands of paint behave differently and mediums allow you to control the paint how you want it to behave as you use it. Some paint manufacturers –and here I’m only referring to the artist grade paints as opposed to the student grades–are stiffer straight from the tube. Student grades have less pigment and much more fillers like additional Rat Poop and simply don’t perform well. If you use those paints which are stiffer from the tube, but need more flexibility in the way they handle, or act, you will require a medium. If you would like brush strokes apparent on your final painting, a lighter paint functions better. Including a refined linseed oil in tiny amounts until it seems right to you will promote the paint to level out and reveal less strokes. Less linseed oil and much more strokes will reveal. Always remember to never place a quicker drying layer on a slow drying coating of paint.
Glazing mediums permit you to apply thin layers of paint and construct colour and luminosity with the viewer’s eye blend the colours as opposed to mixing the paint on the palette or canvas. With a moderate like Liquin by Winsor & Newton speeds drying time when thinning the paint allowing layers to be constructed without waiting a couple of days for each layer to dry before you apply another layer. Additionally, there are glazing mediums accessible like A conventional medium used for decades by many painters is refined linseed oil, a bit of solvent (typically mineral spirits), plus a bit of stand oil, and a touch of Japan or Cobalt Drier These components are blended in a balance to achieve your desired results, such as quicker drying time, more shine, etc.. ) Stand oil is merely a thicker linseed oil which may decrease brush strokes and increase gloss. Adding Damar varnish to your mixture also adds gloss and can accelerate drying time. Damar varnish is made of tree resin and alkyd is a sort of synthetic resin.
There are several mediums and I suggest that you try several until you find what works best for your style of painting.
