Literally “sea foam” in German, meerschaum is a porous white stone, large deposits of which are mined in the villages that surround Eskişehir. While wet, the soft stone is carved into all manner of ornaments, but the smoke-cooling properties of a meerschaum pipe make that the most highly prized item. Several shops around Eskişehir, especially on İnönü Caddesi, work the mineral, and with a little haggling it’s usually possible to pick up a bargain.
