Silicate minerals

Rocks are aggregates of minerals. Many are silicate minerals. This granite, an igneous rock, has Quartz, an amphibole called Hornblende, a pink potassium feldspar, and a white Plagioclase feldspar. Rock-forming Minerals.

Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. Sillimanite is named after the American chemist Benjamin Silliman (1779–1864). It was first described in 1824 for an occurrence in Chester, Middlesex County, Connecticut, US

Talc has many uses for the artist. As a pigment powder it can be useful when making paints. It is good for increasing the opacity of very weak colors while minimizing the chalky look of using straight Precipitated Chalk. In Pastels its greasy feel can modify some pigments that tend to set to too hard a pastel. It can exhibit a pearly luster in some circumstances too.

Aquamarine and Albite Aquamarine is a blue to blue-green variety of the mineral beryl, composed of beryllium aluminum cyclosilicate. It is prized for its beautiful color and clarity and is often used in jewelry. Albite, on the other hand, is a sodium aluminum silicate mineral that typically forms as white to transparent crystals or masses. When aquamarine and albite are found together, they often create visually stunning specimens. Aquamarine crystals can occur embedded within albite…

Silicate: Google’s Definition: “A salt in which the anion contains both silicon and oxygen, especially one of the anion SiO42−.” Text Example: “The Silicates are the largest, the most interesting, and the most complicated class of minerals by far.” Example: My sentence: “Looking over the silicate-ting minerals his eyes glistened.”

Rosasite on Hemimorphite from New Mexico, USA Rosasite is a rare secondary mineral that forms in the oxidized zones of copper deposits. It is known for its vibrant blue to greenish-blue color and often occurs as botryoidal or crusty aggregates. Hemimorphite is a zinc silicate mineral that commonly occurs in white to colorless crystals or botryoidal masses. Specimens from New Mexico, USA, featuring rosasite on hemimorphite, are highly valued by collectors for their aesthetic appeal and the…

Talc Clay Mineral Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula Mg₃Si₄O₁₂. Talc in powdered form, often in combination with corn starch, is a widely used substance known as baby powder.

Science & Origin of TremoliteTremolite is composed of silicate minerals, the main being asbestos, and member of the amphibole group that crystallizes in the form of masses, fibrous aggregates, and prismatic crystals. It was named by Johann Georg Albrecht Höpfner in 1789 after the Tremola Valley in Central St Gotthard Massif, Tessin, Switzerland. After much debate in modern times, it is believed that the type locality material was discovered 14km south in present-day Campolungo Pass, Switzerl

Silica sand, additionally called silica or quartz sand, is a form of difficult, put on-resistant and chemical solid silicate mineral. Its major mineral composition is SiO2. According to distinct mining and processing methods, silica sand may be divided into synthetic silica sand, water washed sand, scrubbed sand, selected (flotation) sand, etc.

Carbon “pulls things out”. Shungite is primarily amorphous graphite (carbon), silicate particles and other minerals. Shungite works at a molecular level to cleanse and align the entire physical body, to the Light body and the Earth. Carbon filters remove contaminants through adsorption. Carbon filters also act as a catalyst to change the chemical composition of some contaminants. Shungite is also a favourite for gem water/tonics due to its filtering abilities. However do not put any mineral…
