Shore durometer The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then read. The material under test should be a minimum of 6 mm (0.25 inches) thick. The ASTM D2240 standard recognizes twelve different durometer scales using combinations of specific spring forces and indentor configurations. These scales are properly referred to as durometer types; i.e., a durometer type is specifically designed to determine a specific scale, and the scale does not exist separately from the durometer.
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.
