Hardened tissue may be fibrosed or indurated.
Igneous rocks are formed when melted rock (magma or lava) from inside the Earth cools and hardens on or under the Earth's surface. This process involves the solidification of molten material, leading to the formation of rocks like granite, basalt, and obsidian.
A batholite is another term for a batholith - a large irregular mass of intrusive igneous rock which has melted or forced itself into surrounding strata.
Calculus is a hardened deposit that forms on teeth.dental calculus
Melted rock below Earth's surface is known as magma. Magma forms when rocks in the Earth's mantle melt due to high temperatures and pressure. As magma rises towards the surface, it can eventually erupt as lava through a volcano.
Encaustic paint is the term for paint that is mixed into melted wax.
