Raising crystals and changing crystal colors


I am trying to raise the crystal, but I don't know how to keep them in the same way but only change their colors

You need to be a whole lot more specific.
What do you mean by "raise"?

What chemical are you crystallising?




If you are interested, take a look at the latest offering from sum_lab:

I think she wants to grow crystals of the same shape, but different colours.

I'd advise using ammonium dihydrogen phosphate (NH4H2PO4, ADP) and a variety of food colourings for separate batches.

Alums have octahedral shape and different colours - aluminum alums are colourless, vanadium alums are green, ferric alums are pale violet, chrome alums are dark violet.

1. A username, made of a real-sounding 1st and last name, with Nospace in between.
2. A female sounding first name.
3. A very short and simple question (not that i have a good answer), almost spoonfeeding.
4.strange grammar. It fits a pattern.

how long is a piece of string really? is it longer than a hole is deep?



~25 drops = 1mL @dH2O viscocity - STP
Truth is ever growing - but without context theres barely any such.

No, How Long is a well-known chemist from Shanghai.
