People recognize a product before they read the label. The shape of a bottle or the pattern on a box may be all it takes. That kind of recognition usually gets filed under modern advertising.

A new study finds that the potters of one walled oasis in northwestern Arabia created a recognizable brand 3,200 years ago. Their vessels have been found more than 80 miles north of it.

Marta Luciani, an archaeologist at the University of Vienna, co-directs the dig at that oasis, Qurayyah, with Ahmed Abualhassan of Saudi Arabia’s Heritage Commission. Her team put 40 pieces of painted pottery under a microscope and through trace-element testing, then compared the results with sherds found elsewhere in the region. The argument rests on clay recipes and chemical fingerprints, not on anything written down. Each site so far has produced matches one fragment at a time.

The pottery is easy to spot. It carries black and red geometric bands, plus stylized animals and human figures. Archaeologists find it across the southern Levant and in Arabia, and for decades they called it Midianite Pottery, after the biblical people of Midian. That name put the pots in the wrong place and the wrong century. Luciani’s team, digging at Qurayyah since 2014, traced the invention to the oasis itself. The Midianites turn up in the Bible in Iron Age settings, by which time this pottery was already out of use.

“It changes everything: first, with the Qurayyah Painted Ware (QPW) moniker we establish a clear connection with its production site, the oasis of Qurayyah, where we now have proven, this pottery was invented and originated,” Luciani told Earth.com.

Qurayyah isn’t a small place. The walled river oasis covers more than 740 acres (300 hectares), and people lived there without a break from the late fourth millennium BCE into the first millennium CE.

Archaeologists have looked for brands in ancient pottery before. The search has mostly been for labels: a stamped seal, a scratched mark, a name pressed into wet clay. Qurayyah’s pots carry none of that.

So the team wrote down eight things that would have to be true for the pot itself to be the brand. Three of them concern the pot: a look you can identify, the same raw materials every time, and the same steps at the wheel over centuries. The other five concern the trade: one production center, proof of export, copies made elsewhere, output beyond local need, and a reputation.

Two of the eight do the heavy lifting, and they are the single place of origin and the intent to sell. Plenty of pottery styles spread across huge areas without either one. The paper offers Late Neolithic Halaf ware as the comparison, coherent to look at but rarely standardized.
