Siltstones do not have a Mohs hardness. Relatively speaking, however, siltstones are relatively easily broken.
Hardness of ductile materials can be determined by following methods..... 1) Brinell Hardness Test 2)Vickers Hardness Test 3)Rockwell Hardness Test 4) Scratch hardness test

There are some differences between hardness and hardenability. Hardness is the surface property of material to give resistance to the penetration or plastic deformation and it is measured by one of the tests......Rockwell hardness test,Brinell hardness test and Vicker hardness test. On the other hand,hardenability is defined as the ability how the material would be hardened and it is measured by Jominy hardenability test.
No, because hardness is not a fundamental quality
No, sodalite is a metamorphic mineral, not a rock. It is a blue mineral commonly found in igneous rocks like syenite or nepheline syenite.

Sodalite is generally insoluble and does not react with acids. It is a stable mineral that is resistant to acid attack, making it suitable for use in various applications.
Sodalite typically forms over hundreds to thousands of years in environments with abundant sodium and aluminum-rich minerals. The exact time it takes for sodalite to form depends on the specific geological conditions, such as temperature, pressure, and availability of the necessary elements.
Sodalite is not magnetic. It is a sodium aluminum silicate mineral that typically exhibits a blue color due to the presence of iron and other trace elements. While some minerals can exhibit magnetic properties due to their iron content, sodalite does not possess the necessary characteristics to be considered magnetic.
Sodalite can exhibit a glow under ultraviolet (UV) light due to the presence of certain minerals and impurities within its structure. When exposed to UV light, some of these impurities can fluoresce, emitting visible light in response. This phenomenon is often seen in specific varieties of sodalite, enhancing its visual appeal and making it popular in decorative applications. However, the glow is not inherent to all sodalite stones and depends on their specific mineral composition.

Sodalite is primarily found in Canada, particularly in the provinces of British Columbia and Quebec. It can also be located in other countries, including Brazil, Namibia, and the United States, particularly in areas like New Hampshire and Arkansas. This mineral is often found in igneous rocks, especially in syenite and nepheline syenite formations. Additionally, sodalite is sometimes discovered in metamorphic environments.
