Adding alum to hot tap water until it no longer dissolves, will create a solution that will allow crystals to form as it evaporates. The size the crystals will be for 2 weeks will depend on growing conditions and if any solution is left.

Why do some igneous rocks have big crystals or grains and some igneous rocks have small crystals or grains?

Igneous rocks with big crystals or grains form from slow cooling beneath the Earth's surface, allowing time for larger crystals to grow. In contrast, igneous rocks with small crystals or grains form from fast cooling at or near the Earth's surface, limiting the time available for crystal growth.


How do you make crystals?

ALUM CRYSTALS you can find alum in a grocery store under 'spices' it is used for pickleingPour 1/2 cup of hot tap water into a clean jar.Slowly stir in alum, a little at a time, until it stops dissolving. Don't add the whole amount - just enough to saturate the water.Loosely cover the jar with a coffee filter or paper towel (to keep dust out) and allow the jar to sit undisturbed overnight.The next day, pour the alum solution from the first jar into the clean jar. You will see small alum crystals at the bottom of the jar. These are 'seed' crystals that you will use to grow a big crystal.Tie nylon fishing line around the largest, best-shaped crystal. Tie the other end to a flat object (e.g., popsicle stick, ruler, pencil, butter knife). You will hang the seed crystal by this flat object into the jar far enough so that it will be covered in liquid, but won't touch the bottom or sides of the jar. It may take a few tries to get the length just right.When you have the right string length, hang the seed crystal in the jar with the alum solution. Cover it with the coffee filter and grow a crystal!Grow your crystal until you are satisfied with it. If you see crystals starting to grow on the sides or bottom of your jar, carefully remove your crystal, pour the liquid into the clean jar, and put the crystal in the new jar. Other crystals in the jar will compete with your crystal for alum, so it won't be able to get as big if you let these crystals grow.Tips:You can use sewing thread or other string instead of nylon fishing line, but crystals will grow on the entire length of the submerged string. Crystals don't adhere to nylon, so if you use it, you can get bigger, better crystals.Alum is an ingredient used to make pickles. It makes them crispy.What You Need:1/2 c hot tap water2-1/2 T alumnylon fishing linepencil, ruler, or knife2 clean jarsspooncoffee filter/paper towelFOR SUGAR CRYSTALS:What You Need:1 cup water3 cups table sugar (sucrose)clean glass jarpencil or butter knifestringGather your materials.You may wish to grow a seed crystal, a small crystal to weight your string and provide a surface for larger crystals to grow onto. A seed crystal is not necessary as long as you are using a rough string or yarn.Tie the string to a pencil or butter knife. If you have made a seed crystal, tie it to the bottom of the string. Set the pencil or knife across the top of the glass jar and make sure that the string will hang into the jar without touching its sides or bottom. However, you want the string to hang nearly to the bottom. Adjust the length of the string, if necessary.Boil the water. If you boil your water in the microwave, be very careful removing it to avoid getting splashed!Stir in the sugar, a teaspoonful at a time. Keep adding sugar until it starts to accumulate at the bottom of the container and won't dissolve even with more stirring. This means your sugar solution is saturated. If you don't use a saturated solution, then your crystals won't grow quickly. On the other hand, if you add too much sugar, new crystals will grow on the undissolved sugar and not on your string.If you want colored crystals, stir in a few drops of food coloring.Pour your solution into the clear glass jar. If you have undissolved sugar at the bottom of your container, avoid getting it in the jar.Place the pencil over the jar and allow the string to dangle into the liquid.Set the jar somewhere where it can remain undisturbed. If you like, you can set a coffee filter or paper towel over the jar to prevent dust from falling into the jar.Check on your crystals after a day. You should be able to see the beginnings of crystal growth on the string or seed crystal.Let the crystals grow until they have reached the desired size or have stopped growing. At this point, you can pull out the string and allow the crystal to dry. You can eat them or keep them. Have fun!If you are having trouble growing sugar crystals, you may want to try some special techniques. A video tutorial showing how to make rock candy is available, too.Tips:Crystals will form on a cotton or wool string or yarn, but not on a nylon line. If you use a nylon line, tie a seed crystal to it to stimulate crystal growth.If you are making the crystals to eat, please don't use a fishing weight to hold your string down. The lead from the weight will end up in the water -- it's toxic. Paper clips are a better choice, but still not great.

Why does alum make big crystals?

It's not that only alum makes big crystals.. There are so many compounds that can make big crystals. Even Sodium Hydroxide makes very good and big crystals. For crystals you need a uniform arrangement of atoms in space. For big crystals all you need is patience. The slower is the crystallization process the bigger crystals are formed. What industries do is called seeding. They make a good concentrated solution of the compound whose crystals are needed and then they put a crystal of the same compound in the solution. The new crystals form and attach to the crystal making quick and big crystals.


How long to make alum crystals?

To make alum crystals, it usually takes 2-3 days for the crystals to fully form. The process involves creating a supersaturated solution of alum, which allows the crystals to slowly grow over time. Patience is key in this process to allow the crystals to reach their desired size.


How do alum crystals grow?

Heat a saturated solution of copper sulfate and water (saturated means it is can not disolve any more) when this is heated pour into a beaker and let it cool at air temp. slowly. DO NOT COOL IT OR HEAT IT! it will take about a week.

How do igneous rocks produce big or small crystals?

The small crystals are formed outside the volcano by the cold air... the cold air cools down the igneous rock and the crystals dont have time to join together so the are small. And the big crystals are formed inside the volcano very slowly and that way they have time to join together then there are big crystals that have been formed.


Where are big crystals are made in volcano?

the magma chamber and then they erupted onto the surface, where the small crystals were formed.
