Ako dlho trvalo, kým sa takéto kryštály objavili v termoske? A aký bol pomer voda:mmc?
Aký bol tiež výťažok vášho prášku oproti vykryštalizovanému mmc - koľko ste stratili v procese kryštalizácie?

Aký podiel vody/4-mmc? Aká je teplota roztoku a pri akej teplote sa má roztok ponechať? ako dlho trvá kryštalizácia?

Aký bol váš postup pri získavaní takýchto kryštálov?

Nie že by som sa tým chcel chváliť, ale kedysi dávno...

Nie. moje skúsenosti s používaním alkoholov (IPA, etanol, metanol) ako kryštalizačného roztoku ukázali, že dostanete malé? kryštáliky podobné piesku. Síce pomerne čisté, ale nikdy nenarástli do veľkých rozmerov.

Dobrý deň.
Toto sa uskutočnilo rozpustením v zmesi voda&acetón. Roztok musí byť číry, nie zakalený alebo hmlistý. A potom sa to nechalo v tmavej kuchynskej skrinke asi týždeň.
Dúfam, že by to mohlo byť užitočné pre vás alebo pre kohokoľvek iného.
