Sheen and No Sheen Areas on Same Surface
Example 3
Wedimadqos SN 0024 (Figure 5), dating to the Post Aksumite period at Ona Adi, also shows different use-wear patterns in magnified images. Figure 6 (sample area circled in Figure 5) has a tribological sheen adhering to the surface. It also shows fractured crystal asperities, which is evident in the irregular and angular light reflections scattered over the surface. Smaller light reflections are coming from debris adhering to the surface and appear as small ‘dots’. From the second sampled area of the surface, Figure 7 below (sample area shown in square in Figure 7), there is no evidence of sheen, the surface is more leveled/smooth, and there is less reflection from individual crystal asperity fractures
