About a Egg tempera
Egg tempera is one of the painting techniques used during the renaissance. Natural pigments are dissolved in a mixture of egg yolk and vinegar (which acts to preserve the color) and are then applied to a wood board primed with a layer of "gesso". Egg tempera is not easily applied; the technique requires thin linear strokes made with small brushes. Egg tempera paintings are long lasting so it is possible for the colors to remain intact for centuries. Leonardo Da Vinci's "last Supper" is an example of egg tempera applied to a wall surface.
卵テンペラの技法
卵テンペラとは、イタリアのルネッサンス期（12-13世紀）に用いられていた技法の一つ。卵黄に水と酢酸（または防腐剤）を入れて天然鉱物や顔料を溶いて漆喰の上に描く手法。絵の具に伸びがなく厚塗りは出来ず、細い線を重ねて完成させる。経年劣化の表れ方が少なく、色彩の鮮やかさを数百年保つことが出来るのが魅力。レオナルド ダ ヴィンチの「最後の晩餐」は漆喰の壁に描かれたテンペラ画。
