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.
the magma chamber and then they erupted onto the surface, where the small crystals were formed.
Since basalt is extrusive it cools quickly and forms small crystals.
Marble plants are in not the real ship
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.
When a magma cools/solidifies, crystals are formed. The quicker the magma cools, the tinier the crystals. A granite for example, which is formed through slow cooling in the Earth's crust, consists out of big crystals. Contrary, magma erupting at the surface (which is then called lava) cools rapidly and consists out of tiny crystals. In extreme cases, the lava cools so rapidly that the resulting rock appears glassy. Hope this helps!
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.
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.
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.
granite!

big crystals form by molten rocks
Yes,the crystals are so big to earn money
