So i tried it again, heating it up and shaking it for a hour.

I pulled it out and leaved it in the freezer for like 2 days.

But the result was again only some gooey layer. Do i need to wait longer ?

of course, in the mixing vessel are some crystals in the very small naphtha layer which i didnt sucked up..

Maybe i should wait longer

Or do the crystals need another surface for building ?

Thanks
