The hardness of bone is due to the calcium salts deposited in it.
The exceptional hardness of bone, which allows it to resist compression, is attributed to the presence of inorganic hydroxyapatites. Hydroxyapatites such as calcium phosphates are particularly important for bone hardness. Organic substances such as collagen fibers contribute to tensile strength, but not to hardness.

Calcium phosphate and calcium carbonate salts.
The deposits of minerals in bone is what makes bones hard. Those minerals which give bones their hardness are calcium phosphate and calcium carbonate.
This depends upon the density of said bones, which has partly to do with calcium intake, among other things
the calcium salts deposited in the matrix give bone its hardness
calcium-phosphate salt crystals
The inorganic portion of bone give hardness & durability but the organic portion of bone give flexibility
Bone Marrow. It is red and is very important to your body!
Bone salts (calcium, mainly) lend hardness; the protein-rich organic matrix permits some flexibility
Due to mineral loss and lower activity, bone density decreases.

Bone is not connective tissue. Instead, connective tissue -- ligaments and tendons -- connect to the bone.
The inorganic portion of bone give hardness & durability but the organic portion of bone give flexibility
it can help make an artificial bone.
Permanent hardness in water is hardness due to the presence of the chlorides, nitrates and sulphates of calcium and magnesium, which will not be precipitated by boiling.

Slate, being a metamorphic rock, would not have a hardness listing on the Mohs scale of mineral hardness.
