Rhyolite magma is rich in silicon, potassium and sodium and erupts at temperatures between 700°C and 850°C as an extremely viscous (sticky) magma. Rhyolite magma containing lots of gas bubbles cools to form pumice. Because it is low in iron, rhyolite is normally light-coloured - it may vary from white to pink or brown.
