Kos tube- 5 kos
Picture: Gabriel Attab
Materiel: Brass, silver 925 and gold
For my second Shabbat Kos series, I chose a brass tube. I first attempted to position it at a 135-degree angle—a tilted, open, vulnerable form, incomplete on its own. It was this fragility that drew me in: how to support it, how to let it stand with grace. But the weight and quantity of the liquid caused the parameters to shift. I then closed one end to turn it into a vessel, and applied the principles I had established during the triangle series: to seek balance with the help of five external elements.
-
First model: a sphere cradles the base, offering an unexpected point of balance.
-
Second model: a frame slips inside the glass, a graphic line that holds and steadies.
-
Third model: a folded metal plate unfolds beneath, grounding the piece like a sculptural shadow.
-
Fourth model: a bridge stretches across, linking the parts in quiet tension.
-
Fifth model: a mirrored twin—an echo of the tube, fused to its base, continuing what the first form could not finish alone.

Kos 1: Tube + Sphere
In this first model, I integrated a sphere into the base to compensate for the tilt and restore the tube’s original height. This nearly hidden volume plays a fundamental structural role—much like a heel in shoe construction: discreet, yet essential to the mechanical stability of the Shabbat Kos.

Kos 2: Tube + Bridge
This curved maillechort plate inspired the idea that the Kiddush cup could rest in its center on this form. In this version, only one edge of the tube touches the ground, creating a minimal point of contact. Yet, the balance remains intact—provided the support is present. A delicate but controlled stability, where the fragility of the tube finds its complement in the supportive curve of the base.
In this version, I wanted to create both stability and a sense of movement through an external structure. The tubular glass is supported by a frame that enters and exits its volume, intersecting it at key points. It finds its balance at a particular angle—neither imposed nor fixed. A tension between support and suspension, conceived for the Kos of Shabbat.

Kos 4: Folded plate
This tubular Kos was designed to rest on an inclined metal plate while maintaining true balance—a complex structural challenge. The angle of the base of the cup is precisely aligned with that of the folded maillechort plate. An internal structure, discreet yet essential, creates the connection between the two elements and ensures the overall stability. The Kiddush cup remains removable from its base.
Kos 5: Reflexion
In this model, I sought to achieve stability by extending a single continuous form. The idea was to conclude the series with a balance born from imbalance.
Here, the piece is a direct continuation of the same brass tube, to which the Kiddush glass is delicately soldered, with only a few points of contact. The glass rests on the original form, to which it is connected, and ultimately reaches an internal equilibrium.
