Technique: Sagged, rotary-polished on the interior, the top and the outside of the rim; fire-polished on the rest of the exterior.

To push against the hot surface of the glass, after the bowl has slumped (Mark Taylor, London).

On the interior, in a circular band at the junction of the side two concentric grooves; another two concentric grooves around the center, both precisely cut. Vertical rim with slightly rounded edge; flattened base, no pontil scar.

Condition: In a good condition, a small internal crack of 0.5 cm. which cannot be felt, not on the exterior nor on the interior, and probably a result of some pollution during the production.
