Hello everyone In this video, I will show you how to grow a beautiful purple, single crystal. For this, we will need the following substances: POTASSIUM CHROMIUM & POTASSIUM ALUMINIUM SULFATE To begin let’s make a mixture of “alum” (Aluminium) To do this, take a glass (cup, container or beaker) and weigh 100 Grams (100g) of Aluminium Potassium Sulfate and 12 Grams (12g) of Chromium Potassium Sulfate in it. Adding *Chrome Alum* will make the crystals voilet Then pour 400ml of very hot water into the glass and stir until all the “Alum” is dissolved after it’s all dissolved, leave this glass, for a few days to let the crystals form at the bottom And then later, pour the “Alum” solution into another container As you can see a lot of beautiful, little, fused together crystals have formed at the bottom of the glass Now we can open the *mass* of the crystals, and put them in a bowl Choose from this *mass* the most beautiful and large crystal This crystal will serve as a seed, from which a large crystal will be grown in the future The solution which previously was submerged, can be now filtered, but that is optional. Now tie a seed on a thin fishing line and hang it, in the solution of “Alum” on a pencil or a stick Now we can only wait for the crystals to grow over time…water will evaporate from the solution and excess “Alum” will form the crystals that is hanging onto the fishing line after some time, the crystal will begin to take a regular dimetric shape that is defined by the crystal lattice of a substance for “Alum” its “octasional” (octagonal) [8 sides] or Octahedron also during the crystal growth excess crystals will grow as well on the bottom and the line of the glass And this shall be removed. it is better to save these crystals as it is possible to prepare a solution and raise other crystals, off of them in the future also, to keep the crystal growing it is important to avoid extreme temperatures and pollution of the solution after two months my crystal has become large enough and i decide that i can stop its growth I pulled all the crystal from the solution and dessicated it’s surface with a napkin next i covered the crystal with colourless nail polish one or two layers *coats* is usually enough It’s important to protect the crystal from further destruction after the nail polish has been dried it’s ok to touch the crystals with bare hands Crystal growth is very exciting activity that develops patience and mind I raised two purple crystals one is dark and the other one is more transparent and bright Now Ladies and Gentleman as we have done a long journey growing these crystals Let’s just enjoy their beautifulness without any further comment. *SUBTITLE*=Citation may be needed, video wording may not be correct/understandable.
