Velázquez Medium is a flowing paste that makes colors slightly transparent while allowing you to build impasto, thick applications of paint. When added to oil paint it does not alter the color temperature. It can be thinned with solvent or oil. Depending upon the proportion added to paint, it does not affect the drying time significantly. Velázquez Medium is softer and ‘longer’* than Impasto Medium, which is ‘short’ or buttery.Velázquez Medium does not contain stearates, solvents, driers or natural or synthetic resins, so it is safe to add to oil paint without the worry of cracking or delaminating.*Long refers to the consistency of paint that displays tall peaks when a palette knife is pressed to its surface and lifted. Long paint is also described as being a “ropy” and refers to a stringy quality, like that of honey. Paint that behaves in this way is said to have long rheology. Short rheology refers to paint that exhibits a more buttery consistency, typical of most commercial oil paint. Rheology is the study of how substances flow, such as liquids and soft solids that flow rather than deform elastically.
