Hourglass (2)

By the 16th c, other uses were common, e.g., preachers to gauge the length of a sermon, tradesmen to count the hours of their work and for cooking times. The sand-glass comes in all sizes: Columbus used a half-hour timer when sailing. Sand may be constructed from lead, tin, black marble dust, pulverized eggshell and white sand mixed with red ochre pigment, as this one, to make red sand.
