Dry ice freeze precipitation sludge ?

[Elliot]

I have my 3rd 4th and 5th pulls sitting on blocks of dry ice.

Rather then freeze precipitating it seems as if the naptha has turned into a sludge?
there is crystals on the bottom but there its a yellowish sludge floating around with it.

is the naptha too cold?

Naphthas also freeze in the dry ice, at least those who contain octanes and above.
