Antonou Tinas (pronounced ANN-toe-noo TEE-nahs) is a glassblower in Tharios. He is Kethlun Warder's fourth cousin once removed and gives Keth work and a chance to regain his old skills after his accident at the Syth. Keth helps him with doing simple glasswork and gets time and materials for his own projects in return. He owns a glass shop on Piraki Road called Touchstone Glass. Antonou only appears as a minor character in Shatterglass.
