Rainbow, glow in the dark and regular

[labdude]

I lay a very thin base color of opal sparkles. Just enough liquid to wet the model, then a very light sprinkle of opal. You can do this or not. Makes for nice sparkle to the ret.
Just lay each color in order, starting at the gingival, and work down into palate, on color at a time. Once the last color is on it will have high and low spots between the colors. Blend this in using the opal sparkles and clear liquid, just lay a coat of this thick enough to fill in low spots. It will finish out nicely.
I use 5 colors for this method and have used up to 9 colors. I use 5 colors as the default. Coral red, Orange, Yellow, Green and Blue. All colors are in powder.
Using liquid colors, they blend into oblivion almost. I find better contrast between the colors using powder for the colors. Use what ever colors you like, as many or few as you like.
First pic should be second. It shows the acrylic as it is when it goes into the pot to cure. Second pic shows the lay up of acrylic just before the leveling layer of acrylic.
