Improbable Oceans was a business-as-form work that produced micro-batches of sea salt from bodies of water that exist only within the overlapping architecture of the global supply chain. By sourcing salt and water from distant origins and merging them under controlled conditions, I generated composite oceans that never existed on Earth but were nonetheless real. These improbable oceans formed through logistical entanglement, market timing, and the coordination of materials and systems of production. Because of the expenses involved in sourcing and production, including satisfying all requirements for commercially produced food items (opening and running a certified food business in a commercial kitchen with extensive insurance), this made the salt the most expensive salt in the world at $1,600 per pound. Each batch of salt indexed a moment when infrastructure briefly allowed two geographies to co-exist in a single crystal. More than a product, the work asked how authenticity is measured, how value is constructed, and what counts as origin in a world increasingly defined by movement and abstraction. Improbable Oceans operated as both document and artifact of an ecology made entirely of supply chains.
