A temperature (from Latin temperare "mix", "moderate") is a stain, the pigments are bound with a binder of a water-oil emulsion. Tempera paints dry compared to oil paints relatively quickly, but this only in the sense that the colors though after the rapid evaporation of the water in part may be revised again, but as oil paints must thicken slowly. The residual oil after evaporation of the water must be oxidized in order to bind the pigments can. This happens more quickly than in the case of oil colors, since the network surface of the oil or the oil globules is higher than that in the continuous oil film of the oil paints.
