Pumice.
The rock formed is very light and is known as pumice or pumice stone.
Pumice is formed by the rapid cooling of gas entrained (frothy) felsic lava which is erupted from volcanoes. If the amount of trapped gases in the lava is high, and cooled quickly enough to trap the bubbles of gas before they can escape, vesicular pumice will be formed, resulting in the only igneous rock that is able to float in water. Obsidian is formed from the extreme rapid cooling of lava.
Pumice is a light, frothy extrusive rock formed when lava cools rapidly, trapping pockets of air inside. Its porous nature allows it to float on water and makes it useful in products like exfoliating scrubs and insulation materials.
Basalt: a fine-grained rock formed from rapid cooling of lava on Earth's surface. Granite: a coarse-grained rock formed from slow cooling of magma beneath the Earth's surface. Obsidian: a glassy rock formed from rapid cooling of lava with minimal crystal growth. Andesite: a medium-grained rock with composition between basalt and granite, often associated with volcanic activity. Pumice: a light and porous rock formed from frothy lava with trapped gas bubbles.
Pumice is volcanic rock formed from frothy lava. It will usually float on water because of all the gas bubbles in it.
Obsidian is a dense, dark volcanic rock formed from fast-cooling lava, resulting in a glassy texture, while pumice is a light, porous volcanic rock formed from frothy lava with trapped air bubbles, giving it a spongy texture. Obsidian is typically black or dark-colored, while pumice is usually light-colored due to its high porosity.

The answer is pitchstone. it is and igneous rock.
Pumice is a volcanic glass that is formed from frothy lava that traps gas as it cools, resulting in a light and porous rock.

Glassy
No, pumice is not foliated. Foliation is a term used to describe the layered structure found in certain rocks like schist and slate, whereas pumice is a type of volcanic rock known for its porous and frothy texture formed from volcanic glass and trapped gas bubbles.
Pumice is a light and spongy rock that forms from lava that is highly frothy with gas bubbles. It is often used in beauty treatments and horticulture due to its porous nature.
