5219 Clear/Lime pigment separation

[Percolation]

I have yellow wax, red wax and lime wax lamps.  The wax remains homogeneous except the lime one.  Deep blue-green pigment particles separate from wax and settle out at the bottom. 

Is this the way its supposed to be with lime green wax?  It's also the worst flowing of all the lamps I have.  It will break down into a bunch of tiny droplets.
