Permanent alcohol-based dyes transform non-porous surfaces into luminous, layered artworks. Tim Holtz Alcohol Inks flow freely across glass, metal, glossy paper, and synthetic materials like Yupo or shrink plastic, creating organic patterns and color transitions impossible with traditional paints. Fast-drying transparency allows rapid layering without muddying, each application adds depth while previous colors show through. The permanent formula resists smudging once dry, letting you build complex surfaces through successive applications.

These acid-free inks excel at spontaneous, fluid techniques. Drop colors onto surfaces and watch them spread and interact, or manipulate them with blending solution for controlled marbling and gradient effects. The concentrated pigments deliver intense color straight from the bottle but dilute beautifully for softer tones. Metallic Mixatives add shimmering highlights when combined with standard colors, creating dimensional effects that shift in changing light. Snow Cap Mixative opens different possibilities entirely: this opaque white creates pastels when mixed with colors, marbleized patterns when layered, and convincing faux patina effects on metal surfaces.

The half-ounce bottles work in airbrushes for fine-mist applications or apply directly for bold color. Mixed media artists use them on everything from jewelry components to resin pours, while paper crafters transform ordinary card stock into jewel-toned backgrounds.
