Fig. 5. Dependence of (A) hardness and (B) elasticity (E) modulus on indentation
depth in the intact waxy surface (filled triangles), the surface treated with
the dental wax (open triangles), and samples covered with wax material
extracted with cold (filled circles) and hot (open circles) chloroform. The
curves represent mean values of 200 indentation tests performed on each sample
type.
