I believe it is talc : )
"protolith" refers to the original composition of an altered rock. for example, a basalt was the protolith to a rock thats presently a greenschist.
The protolith of a metamorphic rock can be any pre-existing rock type, such as shale, limestone, basalt, or granite. The type of metamorphic rock that forms from a protolith depends on factors like temperature, pressure, and the mineral composition of the protolith.
A protolith of sandstone is a sedimentary rock made up of sand-sized mineral grains or rock fragments that have been compacted and cemented together over time. It can form from the erosion and deposition of pre-existing rocks like granite, quartzite, or basalt.
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.
Soapstone is a type of metamorphic rock. Soapstone is also known as steatite or soaprock. It is made from the mineral talc. Soaprock has been used for centuries for sculptures and even kitchen counter tops.

peridotite
No, soapstone is dense, non-porous and does not absorb liquids. Water and oil can be adsorbed by talc and soapstone.

The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
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 protolith of marble was limestone or dolomite.
The protolith of marble was limestone or dolomite.
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.
I would think not, soapstone is very soft and will mark easily
