How many mutually immiscible liquids can be stored in a glass bottle at S.T.P.?

According to

PATTLE, R. E. (1950). Systems of Mutually Immiscible Liquid Layers. Nature, 165(4188), 203–204.

a system of 6 immiscible phases can be formed (including mercury), but the ammonia layer disappears after a month. They suggest gallium could add another layer, giving:

  1. ammonia solution
  2. isobutyl alcohol
  3. liquid paraffin
  4. potassium carbonate solution
  5. methylene iodide
  6. gallium
  7. mercury

Could silicone oil and fluorocarbons create additional stable layers, and have there been any other systems suggested since 1950? I saw a 2006 reference with allegedly 8 phases.

    $\begingroup$ I guess they could. Temporarily there cold be much more layers even from miscible stuff. $\endgroup$ – Mithoron Sep 24 '19 at 0:29

Better than gallium, could the alloy Galistan be used? It’s a mixture of Gallium, indium and tin. Other liquids like Bromine, Cesium and NaK might have some potential but may just react explosively.
