It could be minutes or hundreds of thousands of years depending on the size of the crystal and the method of formation.
A crystal can be formed very quickly. It's the processes that lead to that formation that can conceivably take millions or hundreds of millions of years.
it takes the average crystal 1000 years to form
Anywhere from a fraction of a second to millions of years.
5000 billion years to an hour
how long they stayed in the volcano; how much time the crystals had to form
When magma coos slowly, it allows large crystals to form. The process of evaporation helps to form crystals.
The cooling rate of magma plays a significant role in determining the size of crystals.
Well it depends. But im currently growing salt, suagr and borax crystals and my borax crystals formed first. So i guess my answer is No, borax crystals grow faster but dont take my answer as a fact i could be wrong.
it depends on how long is ban under the ground
millons of years
It takes 2 to 5days
This depends on many factors.
It takes about two to four weeks
salt has stronger and more quality than suger crystals
amphiboles
Most are because they take millons of years to form
Yes. Salts can form crystals (salt crystals).
it could take days to weeks
It can take a couple of days.
how long they stayed in the volcano; how much time the crystals had to form
Because they can take long to form resulting in a large crystal well-formed. And also remeber fast forming Crystal =small, slow forming Crystal =large
