Using an oil bar, also known as an oil stick, is similar to using an oil pastel, allowing you to draw and paint directly onto a surface with concentrated oil paint in solid form. Here's a guide to using them effectively:
1. Preparation is Key:
- Surface: Oil bars work best on surfaces prepared for oil paint. This can include primed canvas, paper specifically designed for oil paint, wood panels, or even metal. Ensure the surface is clean and dry. If using canvas, apply a layer or two of gesso first.
- Materials: Besides the oil bars themselves, gather the following:
- Palette knives or blending tools
- Solvent (such as odorless mineral spirits) for thinning or cleaning
- Rags or paper towels
- A palette or non-absorbent surface for mixing colors (optional)
- Gloves (optional but recommended)
- Ventilation: Work in a well-ventilated area, as solvents can release fumes.
2. Application Techniques:
- Direct Drawing: Oil bars can be used directly like crayons or pastels to create lines and marks. Vary the pressure to control the thickness and intensity of the line.
- Layering: Oil bars blend well, allowing for layering of colors. Apply lighter colors first, then darker colors on top.
- Blending: Use your fingers (with gloves), palette knives, or blending tools to blend colors directly on the surface. This creates soft transitions and smooth gradations.
- Scumbling: Create textured effects by lightly dragging the oil bar across the surface.
- Solvent Use: Dip a brush or rag in solvent to thin the oil bar paint and create washes or glazes. This also helps with blending.
3. Working with Oil Bars:
- Color Mixing: While you can blend colors directly on your painting surface, you can also mix colors on a palette using a palette knife before applying them to the canvas.
- Experimentation: Oil bars are versatile. Experiment with different techniques to find what works best for you. Try combining them with other oil painting techniques.
- Shiva Paintstiks: According to the reference, "Shiva Paintstiks" are a very basic oil stick, good enough for drawing and blocking, though the artist might not use those colours for a finished painting.
4. Drying Time and Finishing:
- Drying Time: Oil bars dry like traditional oil paint, which can take days or even weeks, depending on the thickness of the application and the environmental conditions.
- Varnishing: Once the painting is completely dry, you can varnish it to protect the surface and enhance the colors. Use a varnish specifically designed for oil paintings.
5. Clean Up:
- Tools: Clean brushes and palette knives with solvent.
- Hands: Wash hands thoroughly with soap and water.
By understanding these techniques, you can effectively utilize oil bars to create vibrant and textured artwork. Remember to experiment and explore to develop your own unique style.
