Liquitex Professional Acrylic Ink — Transparent Raw Umber (30ml)

The workhorse of weathering. A transparent earth brown that grimes, dusts and ages anything it touches without hiding the detail underneath — the nearest thing in the range to an all-purpose filter.

Artist-grade Liquitex Professional Acrylic Ink: far more pigment than a hobby wash, thin enough to airbrush straight from the bottle, and lightfast once dry.

• 30ml bottle with dropper insert
• Transparent — builds up in layers
• Airbrush-ready — or thin further for filters and glazes
