Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials. The term is also used to describe a material‘s rating on the scale, as in an object having a “‘Shore durometer’ of 90.” The scale was defined by Albert Ferdinand Shore, who developed a suitable device to measure hardness in the 1920s. It was neither the first hardness tester nor the first to be called a

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.
