Plaster ground on wooden panel, egg-yolk tempera Size: P10 When I go to the forest or park to look for mushrooms, I realize that I am not the only one looking for them. Snails are also looking for mushrooms to eat. I was surprised and felt it was natural that there were rivals in nature. Nature does not belong only to humans, it is a matter of course. This work is made with egg yolk tempera. Egg yolk tempera is painted with egg yolk, vinegar, water, and pigments. The colors are vivid and can be painted with great precision, but it is a time-consuming technique.
