SAL⊥ by BOIR STUDIO

SAL⊥ is a portable saltworks that lets users harvest their own natural sea salt, created by
B O I R, an interdisciplinary Croatian design studio founded by a product designer and a graphic designer turned chef. With SAL⊥, the studio aims to map the authentic tastes of the natural Mediterranean Sea salts, adding brines (concentrated seawater) from different microregions to their collection. SAL⊥ mimics the sustainable process of sea salt creation, which the Mediterranean Sea salt harvesters have been using for millennia. The traditional saltworks have been in perfect balance with nature, as the natural habitat of waterbirds. Today, many traditional saltworks in the Mediterranean are abandoned or transformed, due to the lower cost of industrial salt production. The disappearance of traditional saltworks threatens biodiversity, but it also threatens the rich culinary culture of the Mediterranean.

“SAL⊥ offers a completely new way of serving high quality natural salt. It exhibits unique crystal patterns and allows you to harvest your salt in the most authentic way, applying the T-shaped tool reminiscent of those used by traditional sea salt harvesters. It brings the mystery of salt creation to fine dining tables, engaging foodies in a unique harvesting ritual. It lets you cherish the moment so essential, yet so unknown to most of us. That’s why we invite chefs and restaurant owners to find innovative ways to incorporate SAL⊥ in their fine dining experiences,” explained studio co-founders Vlatka Leskovar-Zidar and Ivan Zidar.
SAL⊥ mimics the process of sea salt creation which the Mediterranean salt harvesters have been using for millennia. It takes only 25 minutes to prepare salt in the restaurant or at home. Pour in a thin layer of brine and heat it up in the oven at 100 °C. When the crystal pattern appears, it’s ready to be served and harvested with a special metal T-shaped tool.

SAL⊥ is a salt container that lets users witness and experience the precious moments of natural sea salt crystals creation and sea salt harvesting.

SAL⊥ is simple to use: pour in a thin layer of bottled brine, that comes with the container, expose it to sunlight for an hour or heat it up in the oven. When the crystal pattern appears, it’s ready to be served and harvested with a special metal T-shaped tool.

Traditional saltworks and salt marshes around them have been a crucial habitat for waterbirds. Overfishing, pollution and climate change have already severely damaged the planet’s largest enclosed sea. Today, many traditional saltworks in the Mediterranean are abandoned or transformed, due to the lower cost of industrial salt production. The disappearance of traditional saltworks threatens biodiversity, but it also threatens the rich culinary culture of the Mediterranean.

Most of us use processed sea salts, that have been whitened to please the eye. The Mediterranean Sea salt is extremely rich with minerals and oligo-elements – there are 80 of them and they disappear during the industrial salt processing. Sea salt created in B O I R’s portable saltworks preserves all the oligo-elements. With SAL⊥ the studio aims to preserve the authentic tastes of the natural Mediterranean Sea salt.
“Our plan is to map the traditional saltworks across the Mediterranean and add their brine to our collection so that every user of SAL⊥ can enjoy and compare the authentic tastes of the natural sea salts from different microregions,” said Vlatka and Ivan.
Ivan’s sea salt research began when he noticed the small pools of seawater trapped in the rocks. He saw the water evaporate, leaving little nuggets of natural salt. That is when the idea for portable saltworks kicked in.
“Traditional sea salt production at the Mediterranean goes through five stages – we’ve studied them at the ancient saltworks along the Croatian Adriatic coast. During the first four stages, the water in salt pans evaporates during the long sunny summer days. During the fifth stage the brine, highly concentrated seawater, is ready to form salt crystals. Natural salt is a lovechild of the sea and the bright Mediterranean sunlight. Those two majestic powers join forces ever since Antiquity to produce one of the most exquisite salts in the world,” said studio co-founder Ivan Zidar.
SAL⊥ is crafted by the best Croatian woodworkers and pottery artisans. Its elegant case comes in a natural walnut or oak with dark oil finishing. The ceramic vessel inside is coated with a waterproof enamel to enable the optimal salt crystallization.
It comes with Nin 28 Bé°, concentrated Adriatic seawater (brine). The cryptic name is derived from the Baumé scale, used to measure the density of liquids. “Nin” stands for the Nin saltworks on the Croatian Adriatic coast. Nin 28 Bé° is the first in the collection of brines that will accompany SAL⊥.
