r/crystalgrowing

This is my first post here. I grew this sugar crystal at home and wanted to share it with the community. Hope you like it!

It took almost a year to finally get these crystals.

One year ago, I made my very first attempt at growing Mohr's salt crystals. It was a successful "0 to 1" milestone for me. I will probably try it again in the future to see if I can achieve perfectly transparent and crystal-clear ones next time!

​

Started with several ~1mm seed crystals put into the filtered saturated table salt (non-iodized) solution in distilled water. For several days nothing happened, only that seeds got slightly smaller, and afterwards growth started, mainly on crystal corners. In two weeks such salt snowflakes had grown.

By the way, the seeds were put in a water for a second before placed into solution for growth, to smooth surface imperfections and remove attached microcrystals.

The growth chamber is empty container, I to which two smaller containers are placed, one with top open, containing growth medium, and other with lid and small hole in it, containing copper sulphate monohydrate acting as humidity sink.

Although these are pretty, such result is not what was intended, and further attempts will be made to grow monocrystals, preferably clear ones.

If anyone knows, is this result of too fast growth, or something else at play? How to improve growth to prevent it being only on corners, thus preventing dendrites?

Grew these crystals from a kit a few years ago and threw away the packaging, so I can't remember the name. (biggest ones are about 5 cm long, but they were all once in a big chunk before falling apart).
When googling I found the closest match in MAP crystals, but after checking out this subreddit and seeing all the other similar looking crystals I'm no longer sure.
BUT! My actual burning question is:
Can one type of crystal be grown over the top of another?
Can these crystals (depending on what they are ofc) be used as "crystal seeds" for copper sulfate?
What would happen If you put MAP/cirtic acid/borax in copper sulfate solution?
Would it mess with the crystaliztion process? Would it create some interesting reaction? Could it ever grow new crystals faster then it dissolves? (since obviously what's grown in water is water soluable).
All of these questions popped into my head when I thought about how cool it would look if blue copper sulfate crystals were grown on top of clear/white crystals. But I know almost NOTHING about chemistry or crystal growing (aside from this 1 succesfull attempt after many failed ones).

So I decided this mught be a good place to ask this.

These large sugar crystals were grown using the hanging string method. Some of them took over six months to grow. They are quite big, but not perfect — they're opaque and have some irregularities in shape. Still trying to grow a perfectly transparent sugar crystal using the hanging string method.

I made it by reacting cream of tartar and baking soda that I bought from Shopee. I'm not sure if it's piezoelectric, as I haven't done any testing.

MSG crystals I grew and preserved in epoxy resin

It's the most common salt to crystallize but it's my biggest one so far, unfortunately I got some green sediments settling on the cluster one and noticed too late after a layer already was created over it. Stopped it because I ran out of time to change the solution too ofter and it almost started getting out of solution. Smaller one is 148g and the bigger one is 199g

A bit dehydrated but still cool
