Soapstone is a metamorphic rock that is typically non-foliated, meaning it lacks the layered structure seen in foliated rocks like slate or schist. Instead, soapstone has a uniform texture and appearance due to its high talc content.

No, soapstone is dense, non-porous and does not absorb liquids. Water and oil can be adsorbed by talc and soapstone.
A metamorphic rock called steatite or talc-schist transforms into soapstone through metamorphism. Steatite is mainly composed of the mineral talc, which is responsible for soapstone's characteristic smooth texture. Heating and pressure cause the recrystallization of talc, transforming it into soapstone.
The rock you are referring to is talc, which is a soft metamorphic rock composed mainly of the mineral talc. Talc is known for its greasy or soapy feel and is commonly used in cosmetics and as a lubricant.
The protolith of soapstone is usually ultramafic rocks such as serpentinite or peridotite. These rocks undergo metamorphism due to high heat and pressure, resulting in the formation of soapstone.
I would think not, soapstone is very soft and will mark easily
Soapstone can come in a range of colors, including gray, green, blue, and brown. The color of soapstone varies depending on the mineral composition present in the specific slab.
The stone, a variety of talc, was first called soapstone in English in the late seventeenth century; the word is a combination of soap and stone, so-called because it feels soapy to the touch.

The feeling of soapstone depends on the percentage of talc in the stone. It can range anywhere from 20% to 80%. high levels of talc will make the stone slick.
The parent rock of soapstone is typically serpentine. Soapstone forms when talc, a soft mineral, replaces the magnesium in the parent rock serpentine through a process called metasomatism.
