Mars Black vs Carbon Black: Understanding Streaks and Mediums
When embarking on a project that contrasts Mars Black and Carbon Black, it's crucial to delve deep into the subtleties between these two powerful, yet distinct black pigments, and consider factors that might influence their behavior on the canvas. Understanding these differences can greatly impact the portrayal of texture, depth, and overall aesthetic within an artwork.
1. Pigment Characteristics:
a. Mars Black: Known for its opacity and relatively fast drying time, Mars Black is an iron oxide-based pigment. It is valued for its strength in creating deep, intense blacks. Mars Black typically has a slightly warm undertone, which can subtly influence the mood of the painting.
b. Carbon Black: This pigment, often sourced from soot, offers a darker tone with a blue undertone, providing artists with an intense, cool black. Carbon Black tends to be more transparent than Mars Black, which can affect layering techniques and the resultant depth of color.
2. Surface and Treatment:
Artists should consider how these pigments interact with the chosen surface. In this case, the use of a canvas board pre-treated with gesso creates a uniform surface that aids in providing the necessary grip for multiple layers of paint. Gesso treatment can reduce the absorbency of the canvas, allowing both Mars Black and Carbon Black to retain more of their color intensity and subtleties.
3. Usage of Mediums:
Incorporating a gloss medium can significantly influence the finish and texture of these black paints. A gloss medium will enhance the depth of color and add a reflective quality to the surface. Since the artist is aiming for a glossy finish, the medium also serves to unify the different characteristics of Mars and Carbon Black, potentially reducing any undesirable streakiness by aiding in smoother application and leveling the paint surface.
4. Application Techniques:
Considering the application of multiple layers is essential for capitalizing on the differences between Mars and Carbon Black. Thin layers of Carbon Black can create translucent shadows and a sense of depth, while Mars Black can contribute to solid, opaque areas. The thickness and method of application can be experimented with to achieve desired textural contrasts.
5. Lighting Considerations:
The intended lighting conditions for viewing the artwork are indispensable in shaping the artwork's presentation. Since lighting can dramatically influence perception, the gloss finish may produce highlights and lowlights that enhance the texture and depth provided by the black tones. It is important for the artist to test how the artwork appears under different lighting scenarios to ensure the intended effect is consistently achieved.
By thoroughly understanding these facets, artists like Allison Prior can effectively employ both Mars Black and Carbon Black to explore contrasts, enhance textures, and ultimately enrich their creative expressions.
