What Does Slate Feel Like?

What is the texture of slate?

Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock.

How can you tell the difference between shale and slate?

Shale has quite a dull look whereas slate shines and looks silky in the sun. Moving on, when treated with water, shale will give you an odour like clay but slate will usually not have any noticeable odour. In some cases however, it may smell like clay but have a very weak odour.

How strong is Slate?

Slate is considered to be in between 2.5 to 4 on this scale in terms of hardness, which means that it is, on average, almost as hard as marble and limestone, but not as hard as granite or natural quartz.

What are properties of slate?

Slate is a fine-grained, foliated metamorphic rock that exhibits slaty cleavage. It forms from the low grade metamorphism of sedimentary shale deposits, and takes its color properties from the minerals contained within its parent rock, shale.
