Williamsburg Extender Medium: Volume Enhancement with Consistency Integrity
Williamsburg Extender Medium is a specialized technical additive formulated for artists who need to increase the volume of their oil paint without compromising its physical handling characteristics. By utilizing a high-density blend of mineral solids, this medium allows for the economical extension of costly pigments while maintaining the "short" and buttery feel of professional-grade oil colors. It is an indispensable tool for large-scale works and impasto techniques where maintaining the original viscosity of the paint is paramount.
Key Features and Artistic Benefits
- Mineral-Based Composition: Formulated with a precise mixture of marble dust and barium sulfate to provide structural bulk and weight, ensuring the extended paint retains its professional feel.
- Consistency Preservation: Specifically engineered to extend the reach of oil paint without thinning it, allowing the artist to maintain identical brush resistance and texture throughout the application.
- Semi-Transparent Optical Profile: Dries with a semi-transparent quality that allows for the extension of colors while preserving a significant degree of their natural depth and luminosity.
- Moderate Drying Rate: Features a balanced drying profile that integrates seamlessly into standard studio workflows without significantly accelerating or retarding the oxidation of the paint film.
Application and Usage Guidelines
- Optimal Mixing Ratios: For best results and to maintain film stability, add this medium to oil paint at a maximum ratio of 1 part Extender Medium to 1 part oil color.
- Additive Only Requirement: This product is designed strictly as an additive to existing oil colors; it should not be used as a standalone ground or painting medium.
- Tone and Color Considerations: Be aware that the use of this medium will increase the tendency of the paint film to yellow over time; it is best suited for earth tones, dark values, or works where a warm patina is acceptable.
- Surface Cleanup: Use white spirit or turpentine oil to remove wet medium from palettes and to clean professional brushes immediately following the painting session.
