While any oil can be a dispersement medium, a lot of artists are experimenting with Silicone Oil by dropping it onto freshly poured, tinted resin to create some really great cell effects.

Silicone oil repels the resin, pushing it away, and this movement is what creates the cell structures.

TIP - Just be aware that the oil also prevents the resin from adhering to your substrate which will result in bare spots in your cured resin!

If you want to cover these bare spots, you'll need remove all of the oily residue by wiping your piece down with a mineral water ( like Perrier ). 
You'll then need to sand your piece down, and once you've wiped away all of the debris, you can apply a fresh coat of ArtResin.

If you used a lot of silicone oil, you may need to seal your sanded work down with a good quality sealant, thereby creating a barrier which will prevent any remaining residue from creating further bare spots in your fresh ArtResin pour.

Also be aware, especially on pieces with a lot of white areas, that silicone oil is highly prone to yellowing and will cause your work to discolour over time.
