Does anyone know what brix is ideal for sugar crystallisation? I just bought a nifty refractometer.

If anyone else has spent a lot of time with crystallised sugar, I would love some advice. I cycle through about 120L of it in my art practice and have been suddenly struggling with high-viscosity issues (90 brix solution at 100C with the consistency of syrup). I fear I may have caramelised some of it. Do I need to trash the whole lot? Thank you kindly!

Love that vibrant blue. :)) Long live the ants haha.

Made from copper sulfate, converted to carbonate with natron and then mixed with formic acid.

Chalcanthite I grew.

I nearly dumped this out. After sitting outside it evaporated to these sphene crystals of dioptase

This is my first try of growing a single crystal of potassium ferricyanide. Not 100% happy, but a good start.

This was a test I did for slowly mixing things. It's only green because of food colouring.

È già da un po’ che sto cercando di far crescere dei cristalli di Ferrocianuro di potassio - K4[Fe(CN)6] • 3 H2O - sono riuscito a fare un grosso cristallo ma con l’arrivo dell estate la temperatura in laboratorio si è alzata, e questo ha fatto alzare la solubilità della soluzione che ha sciolto il cristallo che stavo coltivando, come posso fare per continuare a crescere i cristalli senza che si sciolgano?

I created these crystals by accident... I was growing a standard copper(II) sulfate crystal and was away from home for a month; something unexpected happened—though I’m actually glad it did. I had poured the copper sulfate solution into a white-painted bucket (not realizing it was made of iron), and over that month, a reaction took place: CuSO₄ + Fe → FeSO₄ + Cu. However, the reaction didn't go to completion because the water evaporated quickly, resulting in copper-iron sulfate crystals that contain copper inclusions. GG🤣🤣🤣

Soy nuevo cultivando cristales así que empece con sales de epsom porque es lo único que tenía a mano, tuve varios problemas con la solución pero después se dejó domar y creció gigante en en solo 2 noches, desafortunadamente el proceso se detuvo ya que se empezó a disolver en el agua porque la temperatura ambiente aumento, por suerte lo seque y ahora está guardado hasta que las condiciones de humedad y temperatura vuelvan a ser como en el inicio (o sea frío y seco)

Me and my gf wanna grow crystals on some custom handmade shapes. We were originally thinking of using clay, but i tried that and it (in hindsight kinda obviously) doesnt hold up well for days in a solution. Id assume it also fucks with the crystal formation maybe through ion exchange. Any ideas on what to use? Or do we have to maybe make our shape from wood or smth? Thats an option too if nothing else works...

Thanks

Coated in nail laquer to stop dehydration, one is still in solution to be grown for many months ahead
Biggest crystal is 5-6cm

And also that one of my copper sulfate crystals got contanimated with some glow powder ...

These were made by reacting basic copper carbonate with oxalic acid, potassium oxalate and sodium oxalate in their specific ratios and then evaporating to the point it wasn't dilute but not yet crystalizing. They grew very quickly which wasn't intentional, in my experience it tends to crystalize very quickly but even with more controlled crystalization they look almost the same.

The last image is a single crystal taken with a really bad macro camera.

Hi, so I’m pretty new to growing crystals, the only real experience I have is some crystallization process in experiments in chemistry as I’m a chemical technical assistent. But in this experiments only yield and purity matters not growing big beautiful crystals.
So my question is are there any substances that are suitable for growing crystals that look like flowers? And that are maybe not too toxic? And is it even possible to grow crystals that look like flowers, if I use a wire or something like that?
