Description
Williamsburg Extender Medium is a professional oil painting additive developed to increase the volume of oil paint without changing its original consistency. Made using marble dust and barium sulfate dispersed in linseed oil, this semi transparent medium allows artists to extend their colors while maintaining control and texture. It offers a moderate drying rate and is ideal for traditional oil painting techniques where paint economy and surface build are required. Best used in a controlled ratio as an additive, this extender is suitable for experienced artists seeking reliable studio performance.
