Soapstone and Antler Origins


Soapstone

Soapstone is a metamorphic rock having a talc base ("metamorphic" means changing from one type of stone to another through time and pressure). It occurs as a secondary mineral formed as a result of the alteration of olivine, pyroxene,and amphibole. The purest talc is used commercially to make talcum powder. Soapstone can be distinguished by its' ease of carving, soapy feel, and vibrant colour, which is obtained by the associated minerals leaching into the talc.

Steatite is a massive and compact rock containing more than 90 % talc. The remainder consists of silicates (chlorite) and/or magnesium carbonates.

Soapstone is a massive, soft, impure talc rock that contains variable proportions of magnesian carbonates (dolomite and/or magnesite), serpentine, chlorite, tremolite and magnetite.

Pyrophyllite is a hydrated aluminum silicate. In contrast to talc, pyrophyllite is the product of hydrothermal alteration of felsic igneous rocks (rhyolite, dacite) and schists derived from metamorphosed volcanic ash. Nonetheless, its physical properties are identical to those of talc, and it therefore provides an ideal substitute for talc in a number of industrial applications.

Breunerite is ferroan (iron-rich) magnesite.

Mohs Scale
In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.


Antler
Antlers are unique to cervids and found mostly on males: only caribou and reindeer have antlers on the females, and these are normally smaller than those of the males.

Each antler grows from an attachment point on the skull called a pedicle. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone.

In most arctic and temperate-zone species, antler growth and shedding is seasonal and controlled by the length of daylight. In tropical species, antlers may be shed at any time of year.

Antlers function as weapons in combats between males, which sometimes cause serious wounds, and as dominance and sexual displays.

In moose, antlers appear to act as large hearing aids. Moose with antlers have far more sensitive hearing than moose without, and a study of trophy antlers with an artificial ear confirmed that the antler behaves like a parabolic reflector.

Gathering shed antlers or "sheds" attracts dedicated practitioners who refer to it colloquially as shed hunting, bone picking or sometimes clinting.  In Canada shed hunting usually occurs after the snow melts. Sheds often accumulate in one area, and these areas are often kept secret by those who hunt there.

Shed antlers have been used by craftspeople since ancient times to make tools, weapons, ornaments, and toys.


A horn is a pointed projection of the skin on the head of various animals, consisting of a covering of horn (keratin and other proteins) surrounding a core of living bone.
Horns usually have a curved or spiral shape, often with ridges or fluting. In many species only males have horns. Horns start to grow soon after birth, and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core).
Animals have a variety of uses for horns and antlers, including defending themselves from predators and fighting members of their own species for territory, dominance or mating priority.
