A. Boil the tap water. Add the powdered Alum to the boiling water and keep adding until the solution is supersaturated. Cool the solution. The crystals will form.

Why does alum crystals won't crystallize?
Q. I've been working on growing crystals and so far I can't make a seed crystal from alum crystals. Whenever I set them aside on a saturated solution within 24 hours or more, tiny crystals form on the bottom of the jar instead of a single seed crystal. I had researched too that alum crystals tend to form one big clump of crystal rather than small, tiny crystals. What it causing this? And what are some procedures to make a single seed crystal rather than a carpet of tiny crystals? Thank you.

A. You need to keep the saturated solution warmer to discourage fast crystal formation. Over time you may try letting the crystal form and if you have 1 larger than the others very carefully warm th solution to dissolve completely the smaller ones while the large one only partially melts. Each time you do this more of the alum will move to the large crystal and make it grow even if smaller ones start up again. THis will be slow and need quite a bit of repetition. Try suspending the seed crystal on a piece of (ideally) platinum or gold wire. Or string. Make sure the bottle you are using is completely clean and preferably very smooth. THis will discourage the precipitation around on the bottom of crystal seeds. You may be working with an over… [cont.]

What are the Crystal Structures of these crystals? (Please help)?
Q. I need the crystal structures of Borax crystals and Alum crystals.. And Bluing Solution crystals. Any of the above would be much appreciated
Asked by eddy munstrub. - Mon Mar 12 18:55:41 2007 - Chemistry - 2 Answers - Comments
A. Borax is Hydrated sodium borate. The crystals are monoclinic (2/m). Alum is Aluminium potassium sulfate hydrate. The crystals are Isometric - Diploidal. Blueing solution is Ferric Hexacyanoferrate. These are encased in Sodium chloride (which has cubic structure).

Q. how do u grow a big alum crystal from smaller, or powdery alum?
Asked by bingy33 - Sun Apr 22 12:57:12 2007 - Chemistry - 1 Answers - Comments
A. Crystals grow from a saturated solution. You can make a saturated solution by dissolving as much of the Alum as you can in hot water, pouring off the clear liquid then letting it cool to room temperature. Many small crystals will form. One of these can be used as a seed crystal to grow one large one or you can let the solution evaporate and a large mass of crystals will grow on the bottom. Getting a large perfect crystal is tricky but can be done by tying a fine thread around a single seed crystal and hanging it in the saturated solution and letting it grow slowly by evaporation. Before hanging it in the solution briefly dip the seed crystal in pure water to dissolve the many small seeds on the surface of the larger seed crystal. The link… [cont.]

A. You could make sugar, salt or even other crystals (Cu SO4 crystals are pretty). Some might not work that well, but it depends on a few things like how fast you let the solution cool. Same method as the alum crystals I guess. Heat up some water (or ethanol or an organic liquid, in a steam bath, if what you want doesn't dissolve in water). Add a bunch of the substance in powder form, keep stirring and adding in powder until it won't dissolve any more (the solution is now saturated). Put the saturated solution into a container to cool (you want it to cool as slow as possible, so you may need to heat the container if it's glass).

A. Generally, alum crystals are colorless. They would only be blue if they had been dyed, and it is somewhat difficult to create dyed crystals (the crystals tend to exclude impurities like dyes from their structure). You could try to grow them yourself from alum (available at a grocery or drug store) and blue food coloring. You could also buy one of those crystal growing kits sold to children - often, alum is one of the chemicals used to make the crystals, and it will have been premixed with the correct amount of dye. Purple alum crystals are much easier, because you can use chromium alum, which is purple. It also forms a solid solution with ordinary (aluminum-containing) alum, meaning that you can make different shades of purple by mixing… [cont.]

why do alum crystals grow?
Q. what set of conditions causes alum crystals to grow? why does the water have to be saturated fully with alum in order for the crystal to grow? Does the growth of the crystal have anything to do with concentration of the alum crystal molecules? If so, why?
Asked by Michaela - Thu Feb 3 19:48:44 2011 - Chemistry - 1 Answers - Comments
A. As for your questions, the water has to be saturated so that as it evaporates, the alum molecules get closer together until they start to form crystals. The slower they grow, the more perfect they can be. Speed is not good. Once a crystal starts, the concentrated alum in solution will automatically lay down its atoms in the right places to make the crystal grow bigger. Since they have no water to float in, they have to settle out. The link below has instructions for how to grow a single large alum crystal. Sometimes you think you got everything right but the crystals don't grow right., Just re-dissolve them and try again. Use clean glassware, etc, and clean gloves when handling the crystals. Skin moisture and oil can make the crystal grow… [cont.]

In crystal growing is is celebrated as one of the easiest chemicals to use for growing large, clear crystals. It naturally seems to prefer to to grow a few large crystals over many small ones.

A. Ideally the solution that cooled more slowly should have the bigger crystals. There may have been dirt in your solution that prevented the crystals from growing bigger. Also if you have several crystals growing in the same solution they will all be smaller vs having one crystal growing in a solution.

Q. Where can I find Potassium Aluminum ( Potash Alum ) ?
Asked by Gummie Bear - Fri Nov 13 22:57:45 2009 - Other - Science - 2 Answers - Comments
A. Look for aluminum sulfate at a chemistry supplier. It is commonly used in taxidermy, so oddly, a website specializing in leather and taxidermy might have it. However, since the chemical is toxic to humans in surprisingly small doses, the EPA regulates it, so if you can get it, it will probably be a very small quantity. This will also sound silly, but it is an important ingredient in many Chinese traditional medicines, so that kind of store might also sell it. Finally, there are science websites for home-experimentation of exactly what you're trying to do. Apologies for not being able to provide you with something more specific.
