Fabric also includes a large amount of fine sand particles. Rotational striations are evident on both surfaces, particularly the external base surface and the base-body break where formational movements created some deeper striations. External surface has a slight sheen, but I wouldn\\\'t say polished. Nested base hatches are each approximately 1.5cm long. The internal surface is slightly rough and shows extruding inclusions. No noticeable mica pops or corrosion.
