THE MINERAL APOPHYLLITE Apophyllite, whose name roughly means to leaf apart in Greek, is a mineral classic. It was given its name because crystals tend to peel or flake apart when they are heated due to the loss of water molecules. Although not that well-known by the general public, apophyllite is quite popular among mineral collectors.

Ammolite Ammolite is an opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains of North America. It is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineral contained in nacre, with a microstructure inherited from the shell. It is one of few biogenic gemstones; others include amber and pearl.

- Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO 4. It is a salt consisting of K+ and MnO− 4 ions. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent.It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. In 2000, worldwide production was estimated at 30,000 tonnes.ormerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent.

Get to know your potting mix: Vermiculite and perlite But it’s a harmless mineral and, like vermiculite, sterile and inert. Each material has its uses. For seed-starting, I go with a vermiculite mix for my germination but a perlite mix for growing in pots. A mix containing both can also be valuable. It is easy to mix your own, but make sure you buy horticultural-grade vermiculite and perlite. Both are available from places that sell gardening supplies, bricks-and-mortar and online.

- The volcanic glass, or perlite, is formed when lava (molten rock) spews out of a volcano, and cools in a rapid manner. Because of rapid cooling, water is trapped within the rock, and the lava forms into a glass-like structure.

Dolomite Dolomite, also known as dolostone and dolomite rock, is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.olomite is thought to form when the calcite (CaCO 3) in carbonate mud or limestone is modified by magnesium-rich groundwater. The available magnesium facilitates the conversion of calcite into dolomite (CaMg(CO 3) 2). This chemical change is known as dolomitization.

The Differences Between Vermiculite Vs. Perlite and When to Use Each Vermiculite can soak up 3 to 4 times its volume in water. It also attracts plant nutrients such as potassium, magnesium, calcium and phosphorus. Perlite is an amorphous volcanic rock that is rich in silicon. When mined for use as a potting medium, perlite is crushed and also heated to expand the particles.

What is Vermiculite? Vermiculite is a hydrated magnesium aluminum silicate mineral which resembles mica in appearance. It is found in various parts of the world including Australia, Brazil, Bulgaria, Kenya, Russia, South Africa, Uganda, USA and Zimbabwe. Vermiculite is mined using open cast mining techniques where the ore is separated from other minerals and then screened or classified into several basic particle sizes. Every care is taken in mining operations to minimize the impact on the environment and to restore land to its natural condition when mining ends.
