Correct answer: To apply paint with texture and mix colors
A palette knife is a versatile tool in decorative painting, primarily used for mixing paints directly on the palette to achieve desired colors and consistencies. It is also excellent for applying thick, textured layers of paint to the surface, creating impasto effects and adding dimension to the artwork.
Question 2: Which material is commonly used as a medium for acrylic painting?
- Linseed oil
- Gesso
- Acrylic medium (Correct answer)
- Turpentine
Correct answer: Acrylic medium
Acrylic mediums are specifically formulated to be mixed with acrylic paints to alter their properties, such as consistency, transparency, drying time, or sheen. Unlike linseed oil (for oils) or turpentine (a solvent), acrylic mediums are designed to be fully compatible with acrylics without compromising their integrity.
Question 3: What is gesso primarily used for in painting?
- To clean brushes after painting.
- To remove old paint.
- To add texture to the final artwork.
- To prime the surface for paint application (Correct answer)
Correct answer: To prime the surface for paint application
Gesso is a primer used to prepare a surface for painting. Its primary purpose is to seal the substrate, provide a consistent, slightly absorbent surface for paint adhesion, and prevent the paint from being absorbed unevenly into the material. This creates an ideal foundation for vibrant and lasting artwork.
Question 4: Which tool would you use to achieve fine lines in decorative art?
- Flat brush
- Fan brush
- Liner brush (Correct answer)
- Mop brush
Correct answer: Liner brush
A liner brush features long, thin bristles that come to a very fine point, making it the ideal tool for creating delicate lines, intricate details, and script work in decorative art. Its design allows for a smooth, continuous flow of paint, enabling precise and controlled strokes.
Question 5: What type of paint is best suited for decorative glass painting?
- Watercolor
- Tempera
- Acrylic
- Enamel (Correct answer)
Correct answer: Enamel
Enamel paints are highly durable and adhere exceptionally well to non-porous surfaces like glass, creating a hard, glossy, and often permanent finish. They are frequently heat-set for increased resilience, making them the best choice for decorative glass painting where longevity and washability are desired.

- Acrylic retarder (Correct answer)
- Gesso
- Turpentine
