The process of growing crystals can take several weeks, depending on the saturation of the solution that is used in the initial phases of the process. To follow these methods, you need water, a solute like salt or sugar, rocks, a coffee filter and a stove.Know More
Select a solute that can be used to create a saturated solution. Common choices for a solute for a crystal-growing project include salt or sugar, because they are safe and easy to obtain. A more saturated solution results in better chances of crystal growth. Add your solute to your water after boiling the water on the stove, and mix the solution thoroughly.
Dump the contents of your saturated solution out over the rocks that you have prepared. This results in a clumping of different crystals, known as a crystal garden. Cover the rocks and the solution with a coffee filter.
Wait for the solution you have poured out to dry. The crystals form on their own. This process can take several days or even weeks. The crystals form more quickly if the solution that was created in Step 1 was more heavily saturated with the solute.
Shale is made of silt and very fine minerals that settle to the bottom of a body of water to form a laminated rock. The materials that form silt are the same that form mud. While shale is a mudstone, the laminates create fissures that differentiate it from other mudstones.Full Answer >
Breccia is located wherever fragments of broken rocks or minerals accumulate, such as stream deposits and outcrop bases. The fragments are joined together by small rock particles or cement, which creates the breccia rock.Full Answer >
Granite is an igneous rock that forms when a pocket of magma rises into the upper levels of the Earth's crust and slowly cools. Cooling slowly gives granite, which is composed mainly of feldspar and quartz, enough time to develop large crystals that make the stone very hard and strong. Some granite, known as gneiss, can form from sedimentary rock that has gone through a long metamorphosis.Full Answer >
Stromatolites are large formations of rocks that have been formed by the growth of multiple layers of bacteria over a very long period of time. These usually take the shape of mounds, columns and sheets. Cyanobacteria, single-celled microbes that can perform photosynthesis, develop into these stromatolites. There are many different layers to the various types of formations that stromatolites can take.Full Answer >
