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.
Henrietta Shore to his 40, and at that time a much more established artist. On Weston's urging, Shore travelled to Mexico with her friend Helena Dunlop. It was in Mexico that she was introduced to lithography, a medium which she continued to work in upon her return to California. Her stay in Mexico most certainly influenced Shore's work, as can be seen in paintings like "Women of Oaxaca" in which a line of women in traditional Tehuantepec clothing carry black water jars on their heads. Shore moved to Carmel-by-the-Sea, California in the late 1920s, then an important art colony and resort, following
