About

Generations of Sidonian dye workers crushed millions of murex sea snails along the shoreline, piling the broken shells into hills still visible today. Extracting a few drops of purple-red dye from each mollusk's gland made Tyrian purple worth more than its weight in gold. Workshops operated near Sidon's harbor and kept running straight through the Roman period. The mounds south of the later Sea Castle remain the clearest physical trace of the ancient purple trade.

What happened here

The workshop runs as a production line. Clay is dug locally, weathered over winter, kneaded and thrown, or pressed into moulds for the decorated wares. Vessels are dried under cover, stamped with the potter's name, stacked in the kiln around a central flue and fired for days with the temperature judged by eye and by test pieces pulled from a port in the side. A big firing holds tens of thousands of pots and a bad one loses the lot. Wasters are dumped in heaps beside the works. Some workshops export across half the empire and their stamps turn up thousands of miles away. Fuel is the limit on everything, so kilns sit near woodland and move when it runs out.
