These handmade lights by Israeli designer Ohad Benit mimic the shapes of soap bubbles being formed.

Each of the lamps is supported by a brass framework, which rings the glass shade in much the same way as the circle of a stick used to blow bubbles.

The Stress collection – named to reflect the tension between the two materials – is available as floor lamp versions, pendants, and wall lights held on curved brass wire.

The floor versions rest on minimal metal tripods, with legs dipped in white paint. Benit created the lights in partnership with a local glassblower, after being drawn to the “randomness” of the medium.

Glass is blown into each of the brass rings, before being left to cool and naturally fall into its final shape – making each light unique.

“The materials, reaching their boundaries, are a meeting of two different forms that must adjust to each other; testing their levels of endurance by stretching them, examining the physical encounter between them,” said Benit, whose studio Mishmacool is based in Tel Aviv.

The designer also previously combined glass and brass for a series of insect-like vaseswith just enough room to hold a single flower stem.

“One is tough and elastic, the other hard and brittle, the fluid inflated manually through the brass rod,” added Benit. “I was interested in how such a fluid free material gets constrained.”

The designer had to repeatedly experiment with the process to perfect it, with the glass shades often exploding or breaking along the way.

Stockholm-based Studio EO has also played with the fluid qualities of hand-blown glass, pairing it with marble bases to create a collection of vases that appear as if melting. Lindsay Adelman’s Catch lights follow a similar theme, designed to look as if their glass shades are oozing over brass bases.
