About
Tempera, also known as egg tempera or simply tempera, is a painting medium composed of colored pigments mixed with a water-soluble binder, traditionally egg yolk, though modern formulations often use synthetic emulsifiers. This ancient medium dates back to medieval times and was widely used in European panel painting before the adoption of oil paint. Tempera produces a matte, slightly chalky finish with excellent color saturation and rapid drying time. The pigments are finely ground and suspended in the binder, creating a smooth, workable consistency.
Modern poster paints and student-grade temperas are typically water-based acrylic or synthetic polymer emulsions rather than true egg tempera, making them more convenient and durable while maintaining similar visual and handling properties. Professional-grade temperas still employ traditional egg-based or casein binders, though these are less common in contemporary practice.
Culinary Uses
Tempera and poster paints are NOT culinary ingredients and have no legitimate use in food preparation or consumption. These are art materials intended exclusively for painting and visual art applications. Ingestion of these products poses serious health risks due to the presence of pigments, binders, and additives that are toxic when consumed. Any use of tempera or poster paints must be strictly confined to artistic practice on appropriate surfaces such as paper, canvas, or cardboard.
