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?
it depends on how big you want it. if u only do the process once then only a couple of hours
Do salt crystals grow faster than alum crystals?
No, the alum grows faster.
How does alum affect paper?
Paper sheet having small undissolved alum crystals
How does hydrated potassium alum visually compare to the anhydrous form?
Alum crystals turn into a solid mass of anhydrous alum
Do alum crystals grow better in dark or light?
The dark

How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
What cations can be used to make alum crystals?
either Aluminum or Boron are used in the synthesis of alum crystals
How do you make crystals without alum?

Do salt crystals grow faster than alum crystals?
No, the alum grows faster.
What chemicals make crystals grow the largest?
i like alum, and copper sulphate.
How big are alum crystals after growing for 2 weeks?
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.
How would you test for potassium and sulfate ions in the alum?
by adding acids in alum crystals
