The difference between hornfels and soapstone is that.
Crystals in hornfels grow smaller with metamorphism, and become so small that specialized study is required to identify them. These are common around intrusive igneous bodies and are hard to identify. The protolith of hornfels can be even harder to distinguish, which can be anything from mudstone to basalt. Figure 6.18: Macro view of quartzite.

Hornfels - fine-grained, granoblastic rock of any composition that was produced by contact metamorphism . Should be prefixed by dominant mineral(s) present e.g. hornblende hornfels. This genetic definition is the most widely accepted one, however the term is also sometimes used for any fine-grained rock with a granoblastic texture.Hornfels is available in brown, dark greenish - grey, green, reddish brown colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Hornfels is Dull and that of Schist is Layered and Shiny. Properties of rock is another aspect for Hornfels vs Schist. The hardness of Hornfels is 2-3 and ...
Serpentine is a highly variable stone, in appearance as well as hardness. Soapstone is normally between 1 and 2 on mohs scale (sometimes a bit harder), and can usually be marked with a fingernail. Serpentine cannot be marked by a fingernail, but often can with a blade. Hardness can range from 2.5 to 5.5 or so.Argillite. "Argillite" may also refer to Argillite, Kentucky. Grey chunks of graptolitic argillite on Pakri Peninsula, Estonia; yellowish and white chunks are limestone. Argillite ( / ˈɑːrdʒɪlaɪt /) is a fine-grained sedimentary rock composed predominantly of indurated clay particles. Argillaceous rocks are basically lithified muds and oozes.
The differences between hornfels and soapstone are that soapstone is soft and can be scratched by a fingernail while hornfels is harder and cannot be scratched by a fingernail. Additionally, soapstone is a metamorphic rock that is foliated, while hornfels is also a metamorphic rock but it is unfoliated.
Metamorphic rocks in which minerals are NOT aligned within the rock are: non-foliated. Metamorphic rocks are classified primarily according to: whether they are foliated or non-foliated.

Historically, hornels has been used to construct monuments, cemetery markers, whetstones, artworks, and artifacts. One noteworthy use of hornfels is to construct lithophones or stone bells. In South Africa, the rock may be called “ring stones.”.
Gneiss is a medium to coarse-grained, irregularly banded rock with only poorly developed cleavage. The light and dark bands (gneissic banding) are alternations of felsic vs. mafic layers. Slate is a product of low grade metamorphism (not terribly great burial temperatures and pressures are required).
Soapstones: Soapstones are rocks that contain an abundance of talc, which gives the rock a greasy feel, similar to that of soap. Talc is an Mg-rich mineral, and thus soapstones from ultrabasic igneous protoliths, like peridotites, dunites, and pyroxenites, usually by hydrothermal alteration.

Soapstone, also known as steatite, is a natural quarried stone that is often used as a building material. The natural stone is comprised of mostly talc, while also containing other minerals such as chlorite and carbonates. Because of the high concentration of talc present in the stone, soapstone has a smooth surface.
