Its composed of volcanic ash & sometimes contains larger size particles such as cinders.
Yes, tuff rocks are typically hard due to their composition, which is primarily made up of compacted volcanic ash and other volcanic materials. Tuff is often used as a building material or for ornamental purposes due to its durability and strength.
Tuff rocks primarily contain volcanic minerals such as feldspar, quartz, and volcanic glass, along with various minerals derived from the surrounding volcanic material. Common accessory minerals may include zeolites, clay minerals, and carbonates. The specific mineral composition can vary depending on the source of the volcanic ash and the conditions under which the tuff formed. Overall, tuff is characterized by a mixture of these minerals, reflecting its volcanic origin.
All Igneous rocks are:CrystallineComposed of mineralsFormed from magma/lava (except for 'tuff' which forms from ash, which is a volcanic product)(Please add more)
The luster of tuff rock is typically dull to earthy due to its composition of consolidated volcanic ash and fragments. It does not exhibit a shiny or reflective surface like some other types of rocks or minerals.
Welded tuff is forms when the ash deposited is so hot that it is still partially molten. The still liquid component then cools, fusing the deposit into a single solid mass. Cemented tuff becomes bound together from processes similar to those that form ordinary sedimentary rocks. Grains are bound together under pressure as minerals dissolved in water crystallize.

Welded tuff typically contains minerals such as quartz, feldspar, biotite, and hornblende. The exact mineral composition can vary depending on the specific geologic setting where the welded tuff formed.
Explosive eruptions will produce pyroclastic rocks such as scoria, pumice, and tuff.
Rocks unique to volcanoes include basalt, andesite, rhyolite, scoria, pumice, and tuff.

Other intrusive igneous rocks include gabbro, diorite, syenite, monzonite, granodiorite, monzodiorite, anorthosite, troctolite, peridotite, and pyroxeneite. Extrusive igneous rocks include dacite, andesite, phonolite, and trachyte when classified by composition, and tuff, and scoria in terms of texture.
The homonym for tuff is "tough."
Tough is the same as rough; tuff means cool (ex:a tuff looking Mustang or a tuff record)
