This four-sided bottle is almost square, the base is nearly flat, the profile is straight, and the neck is slightly flared and curved. The body and neck were entirely marvered into a slightly irregular arched and wavy pattern. The pale grey thread is wider and more predominant that the brown and yellow threads.
So-called marvered glass from the Islamic period includes some of the most peculiar and appealing objects produced by medieval glassmakers. The marvered trails, subsequently tooled with a pointed device, into wavy, arcaded, festooned, or foliate patterns, are almost invariably white, or sometimes pale blue, greyish, red or yellow.

This object exemplifies a long-standing tradition of decorative patterns and colours in the Eastern Mediterranean area that continued into the early Islamic period. (LK)
