The recipe to paint that sink was lost for over 300 years. Bringing it back took a Turkish economics professor two years of trial and error with researchers at MIT and Princeton.
The white body is a ceramic mix made mostly of ground-up quartz, the same mineral as glass and crystal. Iranian potters in Kashan invented the technique around the year 1200. They blended quartz with crushed glass and a small amount of clay. The result was almost like porcelain: bright white and able to hold paint without smudging. Persian and later Turkish potters spent the next 500 years perfecting it.
An artisan draws the whole pattern freehand on the bare white body. The pigments are minerals: cobalt for the deep blue, iron for the brown borders, copper for the lighter turquoise. A thin layer of clear glass is brushed over everything, and the piece goes into a furnace hot enough to melt gold. The glass melts and seals every painted line under a glossy coat that can last 500 years.
None of this was ever written down. For nearly a thousand years, the exact ingredients, the firing temperature, the timing, all of it lived only in the heads of the master potters. Apprentices learned by watching. As the Ottoman Empire weakened in the 1700s, demand collapsed, the masters stopped taking apprentices, and the chain broke. The recipe behind the tiles inside Istanbul's Blue Mosque, made in the small Turkish town of Iznik, was gone.
It came back in 1993, when an economics professor named Isil Akbaygil refused to let the tradition die. She set up the Iznik Foundation and brought in researchers from MIT, Princeton, and Istanbul Technical University. The team ran experiments for two years before they cracked the recipe and the coral red glaze that made the original Iznik tiles famous.
Today in the Iranian city of Isfahan alone, around 70,000 artisans still work in 9,000 small workshops, and the province exported over $15 million worth of handicrafts in the year ending March 2024. The sink in your bathroom is the surviving thread of a thousand-year chain that nearly broke.
