How to make alcohol ink art

Alcohol ink art is made by letting fast-drying, dye-based inks flow across a surface that doesn't absorb them. You guide the ink with alcohol, air and tilting rather than a brush, and it dries into glowing colour with crisp, dark edges.

What you need

• Alcohol inks: highly pigmented dyes in an alcohol base. Two or three colours that sit well together are plenty to start.
• A non-porous surface: Yupo (a synthetic paper), glazed ceramic tile, glass, or a coaster. Ordinary paper soaks the ink in, so it can't flow.
• Isopropyl alcohol (91–99%) in a dropper or spray bottle, to move, lighten and bloom the ink.
• Something to move air: a straw, a blower, or a hair dryer on low.
• Optional: metallic mixatives (gold, silver, copper, pearl), gloves, and good ventilation, as the fumes are strong.

Step by step

1. Start with alcohol. Wet the area with a little alcohol first. Ink dropped onto a wet surface spreads further and softer.
2. Drop in colour. Add a few drops of your first ink and let it spread. Add a second colour beside it, close enough that the edges meet while both are wet.
3. Move the ink. Blow across it, tilt the surface, or add more alcohol to push the colour around. Work while it's wet: once it dries, it stays where it is.
4. Make blooms. Drop alcohol into the middle of a wet or dry patch of ink. It pushes the colour outwards into a soft, pale circle with a darker ring (a "bloom" or "cell").
5. Add metallics. A drop of gold or silver near the edges just before the ink dries gathers in the veins and rims.
6. Let it dry and seal it. The ink dries in minutes. On real pieces, seal with a UV-resistant spray and then resin if you want gloss and protection.

Why the edges go dark

As a puddle of alcohol ink dries, the liquid evaporates fastest at its thin edges. Liquid flows outwards to replace it and carries pigment with it, so colour piles up in a crisp, darker line around each shape: the "coffee ring" effect. That's why alcohol ink art has its characteristic rims, veins and cells, and why the middle of a pour is often lighter, with just a soft stain of colour.

Common mistakes

• Too much ink. A few drops go a long way; a flood dries muddy. Build up layers instead.
• Overworking it. Let some areas dry untouched so the edges can form.
• Mixing every colour. Opposite colours that blend in the wet (like orange and blue, or red and green) turn muddy brown. Leave white space between some of them.
• Porous paper. Watercolour or printer paper absorbs the ink, so it stops flowing. Use Yupo, tile or glass.

Questions

How long does alcohol ink take to dry?

Usually a few minutes, faster on warm days and on thin layers. A blower or hair dryer speeds it up.

Can you paint over dried alcohol ink?

Yes, but fresh ink or alcohol re-wets the layer below and moves it again. Seal a layer first if you want to keep it exactly as it is.
