An interesting cabinet
hermetic cabinet, the seams are smeared with sealant, extractor hood, dehumidifier. allows you to maintain a constant temperature and humidity for the isothermal crystallization method

I read his article about this particular cabinet. it's a pity that he stopped publishing his articles, the most interesting ones and did not come out.

here is my result with this method. The method is quite simple and fast. but NaCl or CaCl is not needed here at all. all you need is water and 4-mmc. bring water to a boil and dissolve 4-mmc (1g per 1ml) in it. continue to boil until the surface of the solution is covered with a film. then pour the solution into a glass container with a layer of ~ 5 cm and leave it completely at rest for 10 hours. I did this at a room temperature of + 8C. after 10 hours the crystals are ready
Hi, I have a few questions about your method:
1) What kind of water did you use in this method (distilled, flowing, minimal, bottled),
2) At what temperature the solution was boiled
3) At what point the powder is added, all at once or in certain portions
4) During boiling, stir the solution or leave it alone
5) After boiling, the solution was poured into a crystallization container?

Well-cleaned powder, low dissolving temp and this is what it looks like after standing motionless at room temperature for 18h

Adding vitamin C does not make the slightest sense. The product later appears greasy

I am not saying that I have to be completely right.

I saw a post here on the forum by another user who mentioned an ascorbic acid supplement.

I put down some 4MMC powder from a batch and added the said vitamin C to its crystallisation.

The final crystal with vitamin C, at least in my case, made the crystal very brittle, plus it just got greasy after a few days outdoors.

Who knows, maybe I made a mistake. No less from my side this is how it looked. Regards
