[TheForge] coal or charcoal

[David Childress]

Peter,

When I work in the food oil processing plant they just chilled the oil
and strained it.  Of course what they wanted is mostly what
solidified.  But if you chill the oil to a lower temp than it will see
in use every thing that might gel will have and can be removed.  Sound
like it should do what you need.
