GOLDEN fluid acrylic pigment density

A handy chart of GOLDEN acrylic pigment densities.

Pigment density matters if you're creating a dirty pour fluid acrylic painting.  I write the specific gravity of the pigment right on the paint bottle to make it easier to choose the order in which I layer paint.  Following is an alphabetical list of GOLDEN fluid acrylic paints and their specific gravity.  

Anthraqunone Blue (1.51)
Bismuth Vanadate Yelloe (6.11)
Bone Black (2.52)
Burnt Sienna (3.10)
Burnt Umber (2.50)
Burnt Umber Light (3.35)
Cadmium Orange (5.32)
Cadmium Red Dark (5.03)
Cadmium Red Light (5.40)
Cadmium Red Medium (5.17)
Cadmium Yellow Dark (4.60)
Cadmium Tello Light (4.60)
Cadmium Yellow Medium (4.60)
Cadmium Yellow Primrose (4.60)
Carbon Black (1.80)
Cerulean Blue Chromium (4.20)
Cerulean Blue Deep (4.70)
Chrome Oxide Green (5.10)
Chromium Oxide Green Dark (5.10)
Cobalt Blue (4.30)
Cobalt Green (5.10)
Cobalt Turquoise (4.80)
Diarylide Yellow (1.27)

Raw Sienna (3.51)
Raw Umber (4.42)
Red Oxide (5.00)
Titan Buff (4.10)
Titanate Yellow (4.50)
Titanium White (3.90)
Transparent Pyrrole Orange (1.55)
Transparent Red Iron Oxide (3.90)
Transparent Yellow Iron Oxide (3.70)
Ultramarine Blue (2.35)
Ultramarine Violet (2.35)
Vat Orange (1.50)
Violet Oxide (5.00)
Yellow Ochre (3.50)
Yellow Oxide (4.10)
Zinc White (5.60)

This list is specific to the GOLDEN brand of fluid acrylic paint.  Specific gravity is the ratio of the density of the pigment to the density of water, so for example, Raw Sienna is 3.51 times heavier than water. Knowing this comes in handy when layering paint and determining how the colors will interact with each other.  Since heavier colors want to move to the bottom and lighter colors to the top, if they are layered inversely, with a heavier color on top of a lighter color the colors will move through each other to reach stability, and, in the process create some amazing patterns.  In fluid dynamics this is known as the theory of Rayleigh-Taylor instability.

Does anyone else use pigment density when planning a fluid art pour painting or do you use a more intuitive method?  I'd love to hear your suggestions!
