Tai yra puikus vertimas.

kaip manote, kodėl šaldiklis davė keistus rezultatus kristalizacijos metu?

kaip manote, kaip gerai šis metodas mastelizuojamas?

Dėl vandens, kai jis užšąla, iš kur turėtų atsirasti kristalai?
Įprastas šaldytuvas gal ir veikia, bet viduje turiu savo maisto produktų ir nenoriu jo kaskart valyti.
Tikrai išbandžiau labai daug būdų, kaip pasiekti galutinį produktą, taip pat iššvaisčiau daug tirpiklių ir 2b3c taip pat, bet mano aprašytas būdas man veikė geriau nei kiti bandymai.
Beveik susipainiojau nuo visų skirtingų metodų, visur aplinkui stovėjo įvairūs maži dubenėliai su skirtingais mišiniais, visada žiūrėjau, kuris iš jų gerai vystosi, o kuris ne.
Pavyzdžiui, kai į kristalizuojamą vandenį / miltelius įdedi ledinio ipa, iškart gaunasi šiek tiek baltų kristalų, bet jie nėra skaidrūs ir tik truputį, sp turi kristalizuoti iš naujo, o likusią dalį turi išgarinti, pažiūrėk paskutinę nuotrauką.
Kitose 3 nuotraukose parodyta, kas vyksta su rm mano šaldiklyje, jis tampa kieta mase, kuri tirpsta kambario temperatūroje, bet kristalų nėra.

it depends on how much material you want to dissolve and the water to alcohol ratio.

Is it possible to make 3mmc in powder ? Everyone is talking about acidification with water or acetone and then straight to dish and evaporate. But maybe it is possible to make it like 4mmc. Just putting HcL straight to washed rm and powder forming. Is it possible with 3cmc ? And how to do it with dcm ?

I tried this also. 1st time my HCL was 80% (it perfectly fits for H2O acidification in proper amount) but when only HCL, everything BURNT :)), and second time with 26-38% so drop was sticky flufy mass(then you need MUCH work to get crystals from this shit, and yeld was about 35%.
By the way, in market there is 28% HCL, it comes from latvia.. that shity HCL makes problem with acidification, purple or emerald color goes on, and really hard to achieve optimal ph. All latvian chem in shops ar shit, so dont be fooled.
