Shore durometer B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. Each scale results in a value between 0 and 100, with higher values indicating a harder material. Durometer, like many other hardness tests, measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material, its viscoelastic properties, the shape of the presser foot, and the duration of the test. ASTM D2240 durometers allows for a measurement of the initial hardness, or the indentation hardness after a given period of time.
Summer Evening at Skagen. The Artist's Wife and Dog by the Shore looked up to as a far more competent artist. A few of her works have nevertheless survived. The work is oil on canvas and it measures . Marie Krøyer is shown in profile and her melancholy face and bright dress glow under the light of the setting sun. The painting is one of the works in which Krøyer tries to capture the light and mood on the Skagen shore during what he called "l'heure bleue" (the blue hour), the short period at dusk when the light casts a blue tint over the landscape. The moon's reflection adds a slight feeling
