If half of the jar of CBD crude has crystallized, then you’re looking for something that
A) crystallizes
B) makes up at least half of what’s it the jar.
Not a whole lot of options with decarbed CBD crude as the contents of the jar.
You wanna look at the other options you listed?
They all fail B.
Which one also fails A?
Everything else…
There will be quite a bit of CBD, most of the other cannabinoids that were in the starting crude, the majority of the fats/waxes/lipids/pigments/terpenes/blah blah blah…
