Things You’ll Need
Plain ceramic drinkware (white or off-white works well)
Warm water (if you’ve got especially hard water in your area, use filtered or distilled water)
A container large enough to completely submerse your mugs in (Should not be used for food afterward)
Skewer or toothpick
Bottles of nail polish in complementary colors (the newer the polish, the better)
Step 1: Pour Polish
Fill your container with warm water. With the bottle close to the water’s surface, pour in a little bit of polish (in random squiggles). The polish should spread upon the surface.
Step 2: Swirl
Working quickly, use your skewer or toothpick to swirl the polish, breaking up any concentrated clumps as you go.
Step 3: Dip Slowly
Once the polish has spread thinly across the surface, slowly dip your mug into the water, avoiding the rim of the mug so your lips won’t be touching nail polish while drinking from it.
Lift your mug. The thin layer of polish should have transferred from the surface of the water to your mug to create a marbled effect. Pretty, eh? Set your mug on a piece of paper to dry.
Step 4: Skim Off Excess Polish
If you plan to make more, use your skewer or toothpick to remove any excess polish that remains on the surface of the water so that it doesn’t cling to your next mug.
Once you’ve gotten the hang of working with a single color, start swirling together two or three colors together. Since you’re working against the clock, I’d recommend not using more than three colors in a single dip.
Pour one color in first quickly followed by a second color (and then a third, if using). Swirl them all together with your skewer.
