what's this inside the collection chamber?

• CLS
• ~3.5lbs of material in spool/column.
• ~12lbs of n-butane top washed through
• Dump valve left open from start to finish
• Room temperature n-butane was used to extract
• No dewax jacket/sleeve

1. Usually multiple objects like this can be seen. Sometimes they're very small and combine with each other.
   
2. Floats on top of liquid butane solution
   
3. Creates a depression when it sits on the top layer of the solution, which causes nearby like objects to be absorbed into it if they get too close.
   
4. Phobic/repelled by small bubbles
   
5. Prone to disappear in an instant if they get surrounded by lots of bubbles. (would love a high speed camera for this)
   
6. Usually translucent yellow in color, but I've seen them clear without a color.
   
7. I believe they're first formed through drips coming from the material column.

Looks like ice from the water and super chilling created by evaporating under vacuum.

Thanks guys. Note, the chamber is never reaches vacuum during this phenomena.

So basically this is something that wouldn't happen if the spool and solvent was subzero?

I checked the tank a few days ago for water and found none.
