Marble ink is a thin, flowing nail art ink that spreads into soft veins and stone-like patterns. A'DOR sells classic marble inks, metallic marble inks that leave a gold, silver or bronze line, and foil marble inks with real foil particles for a reflective vein. Each bottle has a fine brush, so you can draw lines straight onto the nail.
The A'DOR listings direct you to work over a cured matte top coat, which helps the ink bloom into soft veins. Draw or drop the ink, let it spread, then cure or let it set as the bottle directs, and seal the design with a glossy top coat. Over a milky base the veins look softer; over a nude or white base they look sharper.
Metallic marble ink leaves a smooth metal-look line in gold, silver or bronze. Foil marble ink contains real foil particles, so the line catches light more like foil leaf. Both are used for veining and accent lines, both are sealed under a top coat, and both come in 15 ml bottles on this page, with some metallic shades also in 10 ml.
Let the ink finish spreading, cure or set it as the label directs, then apply a top coat over the whole nail and cap the free edge. A second thin top coat smooths raised lines. Thin layers hold better than thick ones, and a clean, cured surface underneath helps the design stay put through the wear of the set.
Keep the bottles tightly capped and away from the lamp and from sunny windows, because stray UV light can thicken gel-based inks in the neck. Wipe the brush and the neck before closing so the cap does not stick. Shake or roll metallic and foil inks before use so the particles are evenly spread.
