Pumice and tuff are the product of violent eruptions. Rhyolite is often, but not always produced by violent eruptions, but it can also form from slow, extrusive eruptions.

Is tuff a mineral?
No. Tuff is an igneous rock. it contains a number of minerals as well as volcanic ash and pumice, which are forms of volcaninc glass.
Is tuff an extrusive igneous rock?
Yes. Tuff is an extrusive igneous rock formed by explosive volcanic eruptions.
What turns magma into rhyolite?
Rhyolite is a volcanic rock formed when highly viscous magma rich in silica erupts. In many cases rhyolite comes in the form of tuff, formed when the material is blasted out explosively, forming ash and pumice which eventually settle to the ground. Sometimes this tuff is so hot it gets welded into a solid rock. In other cases it erupts as lava. This lava will either form extremely thick lava flows or pile up on the vent as a lava dome.

What are fiamme?
Squashed pumice blobs in a welded tuff .
What is the difference between tuff and pumice?
Tuff is formed from pyroclastic flows and usually consists largely of ash. Pumice is a vesicular rock formed when bubbles are trapped in solidifying, airborne lava.
