Powder paint is the base for creating the paint used by the masters of the European Renaissance. Tempera paint is a combination of powdered paint pigments, egg and water. Mixed properly, the powder turns into a smoothly applied paint capable of vibrant colours of any imaginable hue. The process of mixing the powder paint is a quick one, using a few basic steps, but the result is a paint with proven results that lasts for centuries.
Crack an egg and separate the egg yolk from the white. Use as fresh an egg as possible for best results in creating a smooth paint. Place the yolk onto the centre of a paper towel and move the yolk toward the edge to remove any remaining egg white.
Pierce the yolk sac with a toothpick and then drain the yolk into a glass bowl. Add one tsp of water to the bowl. Mix the egg yolk and water thoroughly using a small wooden stirring stick.
Pour an equal amount of powder paint into the mixed egg and water. Mix the two completely to create a usable paint. Adjust the thickness of the paint by adding more of the powder to thicken or more water to thin the paint.
Use a fresh hen egg and distilled water for a smoother paint mix.
The yellow of the yolk will alter the initial colour, but its effects will disappear in about a day.
