Time ordered measurements of oil absorption from silica samples produced during one manufacturing shift.
A data frame with 102 observations on the following variable.
a numeric vector
As stated in Nelson, Coffin and Copeland (2003, p. 424), “One key quality parameter in the making of silica is the amount of oil that it can absorb since silica is often mixed with rubber and oil in various applications (battery separators, tires, shoe soles, etc.)”
