'''Gyali''' ({{lang-langx|el|Γυαλί}} "[[glass]]", also spelled '''Giali''' or '''Yali''', pronounced {{IPA-el|ʝaˈli|}}) is a [[volcanoGreece|volcanicGreek]] [[Greecevolcano|Greekvolcanic]] [[island]] in the [[Dodecanese]], located halfway between the south coast of [[Kos]] ([[Kardamaina]]) and [[Nisyros]]. It consists of rhyolitic [[obsidian]] [[lava dome]]s and [[pumice]] deposits (which are mined in huge quantities). No historical eruptions are known, but the most recent [[pumice]] eruptions overlie soils containing pottery and obsidian artifacts from the [[Neolithic period]] (10,000–4,500 BC).<ref name="gvp">{{cite gvp |vn=212051|title=Yali |access-date=2008-01-22}}</ref> The island has two distinct segments, with the northeastern part almost entirely made of obsidian and the southwestern part of pumice. These are connected by a narrow [[isthmus]] and beach made of modern reef sediments. Anciently, the island was known as '''Istros''' ({{lang-langx|grc|Ἴστρος}}).<ref>{{Cite DARE|43443}}</ref>
