Selecting the appropriate substrate significantly impacts the outcome when working with tempera. The surface’s absorbency, texture, and weight directly influence paint application, color vibrancy, and the overall longevity of the artwork. For example, using a thin, non-absorbent paper can lead to paint beading and buckling, while a heavily textured surface may hinder smooth color blending.
Choosing a suitable ground offers several advantages. It ensures optimal paint adhesion, minimizes warping or distortion of the substrate, and enhances the brilliance of the pigments. Historically, artists often prepared their own supports to achieve desired characteristics, indicating an understanding of the material’s crucial role in the artistic process. Proper selection helps preserve the artwork and allows the colors to remain true over time.
